reginfo and secinfo location in sap

It seems to me that the parameter is gw/acl_file instead of ms/acl_file. There are two different versions of the syntax for both files: Syntax version 1 does not enable programs to be explicitly forbidden from being started or registered. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. So lets shine a light on security. The RFC Gateway does not perform any additional security checks. About the second comment and the error messages, those are messages related to DNS lookup.I believe that these are raised as errors because they have occurred during the parsing of the reginfo file. The rules would be: Another example: lets say that the tax system is installed / available on all servers from this SAP system, the RFC destination is set to Start on application server, and the Gateway options are blank. Of course the local application server is allowed access. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Please follow me to get a notification once i publish the next part of the series. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. (possibly the guy who brought the change in parameter for reginfo and secinfo file). This allows default values to be determined for the security control files of the SAP Gateway (Reginfo; Secinfo; Proxyinfo) based on statistical data in the Gateway log. The name of the registered program will be TAXSYS. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_PRXY_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. To control access from the client side too, you can define an access list for each entry. To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . You have already reloaded the reginfo file. You dont need to define a deny all rule at the end, as this is already implicit (if there is no matching Permit rule, and the RFC Gateway already checked all the rules, the result will be Deny except when the Simulation Mode is active, see below). The reginfo file has the following syntax. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. About item #1, I will forward your suggestion to Development Support. If the TP name itself contains spaces, you have to use commas instead. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Its location is defined by parameter gw/sec_info. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. Please note: The wildcard * is per se supported at the end of a string only. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Ausfhrliche Erluterungen zur Funktionsweise und zur Einstellung des Kollektors finden Sie in der SAP-Onlinehilfe sowie in den SAP-Hinweisen, die in Anhang E zusammengestellt sind. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Again when a remote server of a Registered Server Program is going to be shutdown due to maintenance it may de-register its program from the RFC Gateway to avoid errors. Sie knnen die Queue-Auswahl reduzieren. Check the secinfo and reginfo files. You have a non-SAP tax system that needs to be integrated with SAP. Notice that the keyword "internal" is available at a Standalone RFC Gateway (like the RFC Gateway process that runs at an SCS or ASCS instance) only after a certain SAP kernel version. In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule. Part 5: Security considerations related to these ACLs. Its functions are then used by the ABAP system on the same host. In case of TP Name this may not be applicable in some scenarios. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. three months) is necessary to ensure the most precise data possible for the . Save ACL files and restart the system to activate the parameters. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system. The format of the first line is #VERSION=2, all further lines are structured as follows: Here the line starting with P or D, followed by a space or a TAB, has the following meaning: P means that the program is permitted to be started (the same as a line with the old syntax). 2. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for lines with System Type = Registered Server and Gateway Host = 127.0.0.1 (in some cases this may be any other IP address or hostname of any application server of the same system). When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Part 8: OS command execution using sapxpg. Alerting is not available for unauthorized users, Right click and copy the link to share this comment, Part 1: General questions about the RFC Gateway and RFC Gateway security, Part 8: OS command execution using sapxpg, Secure Server Communication in SAP Netweaver AS ABAP. This would cause "odd behaviors" with regards to the particular RFC destination. There are various tools with different functions provided to administrators for working with security files. Someone played in between on reginfo file. Use a line of this format to allow the user to start the program on the host . Programs within the system are allowed to register. Part 4: prxyinfo ACL in detail. In some cases any application server of the same system may also need to de-register a Registered Server Program, for example if the reginfo ACL was adjusted for the same Registered Server Program or if the remote server crashed. You can also control access to the registered programs and cancel registered programs. Somit knnen keine externe Programme genutzt werden. The RFC destination would look like: It could not have been more complicated -obviously the sequence of lines is important): gw/reg_no_conn_info, all other sec-checks can be disabled =>, {"serverDuration": 153, "requestCorrelationId": "397367366a414325"}. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. Most common use-case is the SAP-to-SAP communication, in other words communication via RFC connections between SAP NetWeaver AS systems, but also communication from RFC clients using the SAP Java Connector (JCo) or the SAP .NET Connector (NCo) to SAP NetWeaver systems. Check the availability and use SM59 to ping all TP IDs.In the case of an SCS/ASCS instance, it cannot be reloaded via SMGW. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Every attribute should be maintained as specific as possible. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. The location of this ACL can be defined by parameter gw/acl_info. Always document the changes in the ACL files. Maybe some security concerns regarding the one or the other scenario raised already in you head. The local gateway where the program is registered can always cancel the program. We solved it by defining the RFC on MS. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. A LINE with a HOST entry having multiple host names (e.g. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Part 2: reginfo ACL in detail. In the gateway monitor (SMGW) choose Goto Logged On Clients , use the cursor to select the registered program, and choose Goto Logged On Clients Delete Client . Program foo is only allowed to be used by hosts from domain *.sap.com. Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. As i suspect it should have been registered from Reginfo file rather than OS. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo The RFC library provides functions for closing registered programs. The order of the remaining entries is of no importance. Trademark. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. This is a list of host names that must comply with the rules above. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. Each instance can have its own security files with its own rules. If this addition is missing, any number of servers with the same ID are allowed to log on. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. If you have a program registered twice, and you restart only one of the registrations, one of the registrations will continue to run with the old rule (the one that was not restarted after the changes), and another will be running with the current rule (the recently restarted registration). (any helpful wiki is very welcome, many thanks toIsaias Freitas). Its location is defined by parameter gw/prxy_info. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. If the called program is not an RFC enabled program (compiled with the SAP RFC library) the call will time out, but the program is still left running on the OS level! A Stand-alone Gateway could utilise this keyword only after it was attached to the Message Server of AS ABAP and the profile parameter gw/activate_keyword_internal was set. The reginfo ACL contains rules related to Registered external RFC Servers. secinfo: P TP=* USER=* USER-HOST=* HOST=*. The secinfo file has rules related to the start of programs by the local SAP instance. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. The very first line of the reginfo/secinfo file must be "#VERSION=2"; Each line must be a complete rule (you cannot break the rule into two or more lines); The RFC Gateway will apply the rules in the same order as they appear in the file, and only the first matching rule will be used (similar to the behavior of a network firewall). To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Part 7: Secure communication There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. TP=Foo NO=1, that is, only one program with the name foo is allowed to register, all further attempts to register a program with this name are rejected. Based on the original Gateway log files in the system, default values can be determined and generated for the ACL files directly after the evaluation of the data found. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). This is for clarity purposes. As separators you can use commas or spaces. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). It also enables communication between work or server processes of SAP NetWeaver AS and external programs. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. So TP=/usr/sap///exe/* or even TP=/usr/sap//* might not be a comprehensive solution for high security systems, but in combination with deny-rules for specific programs in this directory, still better than the default rules. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. The secinfosecurity file is used to prevent unauthorized launching of external programs. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Part 6: RFC Gateway Logging. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. RFC had issue in getting registered on DI. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. There are two different syntax versions that you can use (not together). A rule defines. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Only the secinfo from the CI is applicable, as it is the RFC Gateway from the CI that will be used to start the program (check the Gateway Options at the screenshot above). The other parts are not finished, yet. Once you have completed the change, you can reload the files without having to restart the gateway. About this page This is a preview of a SAP Knowledge Base Article. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). ABAP SAP Basis Release as from 7.40 . Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. (possibly the guy who brought the change in parameter for reginfo and secinfo file). See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. Part 4: prxyinfo ACL in detail. To edit the security files,you have to use an editor at operating system level. At time of writing this can not be influenced by any profile parameter. To permit registered servers to be used by local application servers only, the file must contain the following entry. 1. other servers had communication problem with that DI. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Hufig ist man verpflichtet eine Migration durchzufhren. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . If the option is missing, this is equivalent to HOST=*. Depending on the settings of the reginfo ACL a malicious user could also misuse this permissions to start a program which registers itself on the local RFC Gateway, e.g.,: Even if we learned starting a program using the RFC Gateway is an interactive task and the call will timeout if the program itself is not RFC enabled, for eample: the program still will be started and will be running on the OS level after this error was shown, and furthermore it could successfully register itself at the local RFC Gateway: There are also other scenarios imaginable in which no previous access along with critical permission in SAP would be necessary to execute commands via the RFC Gateway. All subsequent rules are not checked at all. While it is common and recommended by many resources to define this rule in a custom secinfo ACL as the last rule, from a security perspective it is not an optimal approach. This section contains information about the RFC Gateway ACLs, and examples of landscapes and rules.The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. Legal Disclosure | Help with the understanding of the RFC Gateway ACLs (Access Control Lists) and the Simulation Mode, in order to help prepare production systems to have these security features enabled without disruptions. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Program hugo is allowed to be started on every local host and by every user. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. The prxyinfo file is holding rules controlling which source systems (based on their hostname/ip-address) are allowed to talk to which destination systems (based on their hostname/ip-address) over the current RFC Gateway. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. The first letter of the rule can be either P (for Permit) or D (for Deny). Please assist me how this change fixed it ? About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. This way, each instance will use the locally available tax system. Refer to the SAP Notes 2379350 and2575406 for the details. The Gateway uses the rules in the same order in which they are displayed in the file. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. This makes sure application servers must have a trust relation in order to take part of the internal server communication. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. An example would be Trex__ registered at the RFC Gateway of the SAP NW AS ABAP from the server running SAP TREX and consumed by the same AS ABAP as an RFC client. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. P means that the program is permitted to be registered (the same as a line with the old syntax). The RFC Gateway is capable to start programs on the OS level. How to guard your SAP Gateway against unauthorized calls, Study shows SAP systems especially prone to insider attacks, Visit our Pathlock Germany website https://pathlock.com/de/, Visit our Pathlock Blog: https://pathlock.com/de/blog/, SAST SOLUTIONS: Now member of Pathlock Group. The following syntax is valid for the secinfo file. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! The RFC Gateway can be seen as a communication middleware. if the server is available again, this as error declared message is obsolete. This parameter will allow you to reproduce the RFC Gateway access and see the TP and HOST that the access is using hence create the rules in the reginfo or secinfo file; 5)The rules defined in the reginfo or secinfo file can be reviewed in colored syntactic correctness. All of our custom rules should bee allow-rules. Part 6: RFC Gateway Logging. Falls Sie danach noch immer keine Anwendungen / Registerkarten sehen, liegt es daran, dass der Gruppe / dem Benutzer das allgemeine Anzeigenrecht auf der obersten Ebene der jeweiligen Registerkarte fehlt. That part is talking about securing the connection to the Message Server, which will prevent tampering with they keyword "internal", which can be used on the RFC Gateway security ACL files. The first line of the reginfo/secinfo files must be # VERSION = 2. Only the first matching rule is used (similarly to how a network firewall behaves). Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. HOST = servername, 10. D prevents this program from being registered on the gateway. If we do not have any scenarios which relay on this use-case we are should disable this functionality to prevent from misuse by setting profile parameter gw/rem_start = DISABLED otherwise we should consider to enforce the usage of SSH by setting gw/rem_start = SSH_SHELL. The wildcard * should be strongly avoided. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. Thus, part of your reginfo might not be active.The gateway is logging an error while performing name resolution.The operating system / DNS took 5 seconds to reply - 5006ms per the error message you posted; and the response was "host unknown".If the "HOST" argument on the reginfo rule from line 9 has only one host, then the whole rule is ignored as the Gateway could not determine the IP address of the server.Kind regards. This is defined in, how many Registered Server Programs with the same name can be registered. To set up the recommended secure SAP Gateway configuration, proceed as follows:. The related program alias also known as TP Name is used to register a program at the RFC Gateway. The wild card character * stands for any number of characters; the entry * therefore means no limitation, fo* stands for all names beginning with fo; foo stands precisely for the name foo. three months) is necessary to ensure the most precise data possible for the connections used. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. This is an allow all rule. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. This is because the rules used are from the Gateway process of the local instance. The SAP note1689663has the information about this topic. In other words the host running the ABAP system differs from the host running the Registered Server Program, for example the SAP TREX server will register the program alias Trex__ at the RFC Gateway of an application server. Very good post. With this rule applied for example any user with permissions to create or edit TCP/IP connections in transaction SM59 would be able to call any executable or script at OS level on the RFC Gateway server in the context of the user running the RFC gateway process. File reginfo controls the registration of external programs in the gateway. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. CANCEL is usually a list with all SAP servers from this system (or the keyword "internal"), and also the same servers as in HOSTS (as you must allow the program to de-register itself). In the slides of the talk SAP Gateway to Heaven for example a scenario is outlined in which a SAProuter installed on the same server as the RFC Gateway could be utilized to proxy a connection to local.
