SAP gateway connection failed

Hi All,

Due to restructure in DMZ in our network, IP addr of our R3 server is changed from 172.20.x.x to 192.168.x.x. and the original IP is NATted for connections. We can able to access SAPGUI, but RFCs from this server to other systems is not working. We are not able to remote logon from RFC to this R3 system from other servers, because of same issue.

RFC Error:

Error Details LOCATION: SAP-Gateway on host <sapr3> / sapgw01

Error Details DETAIL: no connect of TP sapdp00 from host <sapbw> after 20 sec

As per the note, Note 148832 - IP address conversion with a firewall, we have added the BW system entry in gw/alternative_hostnames, still its not working.

Because of this issue we are not able to access this R3 server from BW

as source system check failing with error

The following errors occurred in source system RSAR 374

    • ERROR => GwRqDpSendTo: no comm_adm entry found

    This may be a program error, check [Note 1358616 - Core dump in gwrd|https://service.sap.com/sap/support/notes/1358616] and see if it applies to your kernel version.

    • LOCATION SAP-Gateway on host sapretail / sapgw01

      Where are you getting the above information from, off which host ?

      From what you posted I see data from 3 hosts which is confusing: sapr3, sapbw and sapretail.

      For troubleshooting purposes stick to sapr3 and sapbw. Do you not perhaps have the old ip address of sapr3 in the host file for sapbw system ? You might need to go one level lower and analyse the network data between the two systems using a packet sniffer of some sort, that may be a better idea.
