Trend Micro – Worry Free Business Security – Firewall Port Ranges Failing/Not Working

Posted on July 18, 2011

We recently applied an upgrade from Worry Free Business Security 6.0 SP3 to 7.0. After the upgrade we noticed whitelisted Ephemeral and other port ranges in the firewall policies were not allowing traffic in. After numerous hours verifying everything was correctly setup we got in touch with Trend Micro and they sent back a patch to resolve the issue. We haven't seen this online yet, so I figure this may help a few of you.

Good Day.

Please apply the attached Hotfix to the WFBS Server. Unzip password: novirus
Let the agents update afterwards then observe if the issue persists.

We are looking forward to your reply.

After applying this patch and allowing the update to propagate down to the clients, the port ranges started allowing traffic through.
