during our migration to 9.12 (from 8.2 SP2 via 9.5.SP1) we are currently testing our connectivity from our external partner via Enterprise Gateway in DMZ to our internal application where the process ist residing.
We have done all prerequisites like firewall clearing, port forwarding from external to internal network.
First tests show that partner is able to reach the Enterprise Gateway on network layer but somehow we are not able to detect the incoming messages in RosettaNet/TradingNetworks nor do we see the process instances starting, which should listen to the RN-Messages.
Our Partner just reports “Access denied” errors which are not in our logs.
Service being used for accepting the messages from Partner is pub.estd.rosettaNet:receive which is configured in the TPA for this Partner.
Version is RN 7.1 SP2 Fix16 hosted on IS/TN 9.12 with Fixes ISCore Fix22 and TN Fix11.
eStandards Commons are on 7.1 with Fix15.
Any ideas what we are missing where and how to solve that?
I have already increased the log levels to WmPartnerMgr/TradingNetworks factories to check if there is something in the logs, but unfortunately I was not able to detect any relevant messages related to this issue.
