reginfo and secinfo location in sap

This ACL is applied on the ABAP layer and is maintained in transaction SNC0. The wildcard * should not be used at all. In addition to proper network separation, access to all message server ports can be controlled on network level by the ACL file specified by profile parameter ms/acl_file or more specific to the internal port by the ACL file specified by profile parameter ms/acl_file_int. Every line corresponds one rule. Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? Environment. The syntax used in the reginfo, secinfo and prxyinfo changed over time. The tax system is running on the server taxserver. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. There are three places where we can find an RFC Gateway: The RFC Gateway is by default reachable via the services sapgw and sapgws which can be mapped to the ports 33 and 48. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. It is important to mention that the Simulation Mode applies to the registration action only. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Danach wird die Queue neu berechnet. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. In case the files are maintained, the value of this parameter is irrelevant; gw/sim_mode: activates/deactivates the simulation mode (see the previous section of this WIKI page). We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for programs listed with System Type = Registered Server and Gateway Host set to any IP address or hostname not belonging to any application server of the same system. Trademark. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. How can I quickly migrate SAP custom code to S/4HANA? The related program alias also known as TP Name is used to register a program at the RFC Gateway. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. With this rule applied any RFC enabled program on any of the servers covered by the keyword internal is able to register itself at the RFC Gateway independent from which user started the corresponding executable on OS level (again refer to 10KBLAZE). Please pay special attention to this phase! Part 2: reginfo ACL in detail. However, you still receive the "Access to registered program denied" / "return code 748" error. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_SEC_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: I think you have a typo. Maybe some security concerns regarding the one or the other scenario raised already in you head. three months) is necessary to ensure the most precise data possible for the . From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. 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. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. All programs started by hosts within the SAP system can be started on all hosts in the system. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). 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. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Another example would be IGS. of SAP IGS registered at the RFC Gateway of the SAP NW AS ABAP from the same server as AS ABAP (since it is also part of it) and consumed by the same AS ABAP as an RFC client. Falls es in der Queue fehlt, kann diese nicht definiert werden. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Program cpict4 is not permitted to be started. Thus, if an explicit Deny rule exists and it matches the request being analyzed by the RFC Gateway, the RFC Gateway will deny the request. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. This means that the sequence of the rules is very important, especially when using general definitions. While typically remote servers start the to-be-registered program on the OS level by themselves, there may be cases where starting a program is used to register a Registered Server Program at the RFC Gateway. 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. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). Limiting access to this port would be one mitigation. To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. All other programs starting with cpict4 are allowed to be started (on every host and by every user). For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. The first letter of the rule can begin with either P (permit) or D (deny). The name of the registered program will be TAXSYS. To assign the new settings to the registered programs too (if they have been changed at all), the servers must first be deregistered and then registered again. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. If this addition is missing, any number of servers with the same ID are allowed to log on. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Please assist ASAP. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Every attribute should be maintained as specific as possible. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. The RFC Gateway is capable to start programs on the OS level. 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. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. 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). Part 5: ACLs and the RFC Gateway security Hufig ist man verpflichtet eine Migration durchzufhren. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Here are some examples: At the application server #1, with hostname appsrv1: At the application server #2, with hostname appsrv2: The SAP KBA2145145has a video illustrating how the secinfo rules work. The secinfo file from the CI would look like the below: In case you dont want to use the keywords local and internal, youll have to manually specify the hostnames. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Such third party system is to be started on demand by the SAP system.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.You have an RFC destination named TAX_SYSTEM. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. Part 3: secinfo ACL in detail. No error is returned, but the number of cancelled programs is zero. It is common to define this rule also in a custom reginfo file as the last rule. 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). P TP=* USER=* USER-HOST=internal HOST=internal. The keyword internal will be substituted at evaluation time by a list of hostnames of application servers in status ACTIVE which is periodically sent to all connected RFC Gateways. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. Access to this ports is typically restricted on network level. 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 SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. The following syntax is valid for the secinfo file. Then the file can be immediately activated by reloading the security files. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. 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. Thank you! 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. gw/acl_mode: this parameter controls the value of the default internal rules that the RFC Gateway will use, in case the reginfo/secinfo file is not maintained. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. If the TP name itself contains spaces, you have to use commas instead. 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. As separators you can use commas or spaces. Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. Make sure that they are set as per the Notes: Note 1425765 - Generating sec_info reg_info Note 1947412 - MDM Memory increase and RFC connection error For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. To edit the security files,you have to use an editor at operating system level. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. HOST = servername, 10. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. Part 2: reginfo ACL in detail. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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! In this case the Gateway Options must point to exactly this RFC Gateway host. The first line of the reginfo/secinfo files must be # VERSION = 2. The reginfo file has the following syntax. Its functions are then used by the ABAP system on the same host. In case the files are maintained, the value of this parameter is irrelevant; and with parmgw/reg_no_conn_info, all other sec-checks can be disabled =>SAP note1444282, obviously this parm default is set to 1 ( if not set in profile file ) in kernel-773, I wasted a whole day unsuccessfully trying to configure the (GW-Sec) in a new system, sorry for my bad mood. 1. other servers had communication problem with that DI. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. Terms of use | The Gateway uses the rules in the same order in which they are displayed in the file. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. Part 1: General questions about the RFC Gateway and RFC Gateway security. Please follow me to get a notification once i publish the next part of the series. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. 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. This order is not mandatory. Part 4: prxyinfo ACL in detail. Part 7: Secure communication 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. An example could be the integration of a TAX software. 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. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Now 1 RFC has started failing for program not registered. Use host names instead of the IP address. Part 2: reginfo ACL in detail. All subsequent rules are not checked at all. 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. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. 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. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. The wildcard * should be strongly avoided. Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. Once you have completed the change, you can reload the files without having to restart the gateway. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. You have a non-SAP tax system that needs to be integrated with SAP. Its location is defined by parameter 'gw/reg_info'. There are two different syntax versions that you can use (not together). Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Alerting is not available for unauthorized users. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. The secinfo security file is used to prevent unauthorized launching of external programs. Program cpict4 is allowed to be registered by any host. For AS ABAP the ACLs should be maintained using the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files). Somit knnen keine externe Programme genutzt werden. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. While it is common and recommended by many resources to define this rule in a custom reginfo ACL as the last rule, from a security perspective it is not an optimal approach. In case you dont want to use the keyword, each instance would need a specific rule. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. Only clients from the local application server are allowed to communicate with this registered program. Check the above mentioned SAP documentation about the particular of each version; 4)It is possible to enable the RFC Gateway logging in order to reproduce the issue. In summary, if the Simulation Mode is deactivated (parameter gw/sim_mode = 0; default value), the last implicit rule from the RFC Gateway will be Deny all as mentioned above, at the RFC Gateway ACLs (reginfo and secinfo) section. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Part 4: prxyinfo ACL in detail Someone played in between on reginfo file. Ergebnis Sie haben eine Queue definiert. Somit knnen keine externe Programme genutzt werden. Copyright | The gateway replaces this internally with the list of all application servers in the SAP system. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. 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"}. 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. It is common and recommended by many resources to define the following rule in a custom prxyinfo ACL: With this, all requests from the local system, as well as all application servers of the same system, will be proxied by the RFC Gateway to any destination or end point. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. We made a change in the location of Reginfo and Secinfo file location we moved it to SYS directory and updated the profile parameter accordingly (instance profile). D prevents this program from being started. This is defined in, how many Registered Server Programs with the same name can be registered. The simulation mode is a feature which could help to initially create the ACLs. A custom allow rule has to be maintained on the proxying RFC Gateway only. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* There are other SAP notes that help to understand the syntax (refer to the Related notes section below). Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Privacy | Hello Venkateshwar, thank you for your comment. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. About item #1, I will forward your suggestion to Development Support. 2. The first letter of the rule can be either P (for Permit) or D (for Deny). Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. Since this keyword is relaying on a kernel feature as well as an ABAP report it is not available in the internal RFC Gateway of SAP NW AS Java. As i suspect it should have been registered from Reginfo file rather than OS. Please assist me how this change fixed it ? Read more. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. 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. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. We can look for programs listed with Type = REGISTER_TP and field ADDR set to any IP address or hostname not belonging to any application server of the same system. In these cases the program alias is generated with a random string. They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. 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. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. 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. The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which Registered Server Programs (based on their program alias (also known as TP name)). In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_REG_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. The default configuration of an ASCS has no Gateway. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. As i suspect it should have been registered from Reginfo file rather than OS. If no access list is specified, the program can be used from any client. If the Gateway protections fall short, hacking it becomes childs play. Part 5: Security considerations related to these ACLs. To control access from the client side too, you can define an access list for each entry. To prevent the list of application servers from tampering we have to take care which servers are allowed to register themselves at the Message Server as an application server. 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. It might be needed to add additional servers from other systems (for an SLD program SLD_UC, SLD_NUC, for example).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).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): You have a Solution Manager system (dual-stack) that you will use as the SLD system. 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 When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. This means the call of a program is always waiting for an answer before it times out. Part 7: Secure communication Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal.
