Environment
Novell GroupWise 8 Support Pack 2 Hot Patch 2
Situation
Post office is configured to use the standard internal port of 1677 and an external non standard port 21677. A firewall uses PAT to translate 21677 to 1677 for external user connections. The external UDP requests are addressed to 1677 instead of 21677.
Resolution
Workaround Fix: Allow incoming UDP requests to 1677.
