Server is OES2 Linux SP1, GroupWise is 8.0.1.

At around noon today, users at one of our schools could no longer attach to their post office. No connections are being accepted to any of the POA ports (1677, 7181, etc.) remotely. However, from the server, you can make connections to all the ports fine. Linux firewall is disabled. Users can ping server and access NSS volumes fine.

Settings in ConsoleOne look fine and have rebuilt wphosts.db file. Have also uninstalled RPMs/reinstalled/reconfigured.

Not sure where else to look. It's acting as if firewall IS on, but have verified that it's off.
