Running Comodo Firewall 5.12.256249.2599. It has served me well, but ran into a bit of problem with Plex Media Server. (plexapp.com)
Installed Plex Media Server, which works great... inside my LAN. My PC runs PMS fine, and I was able to access it with multiple clients on different PCs (mainly through a Netopia 3000 DSL wifi router), and even the Android client works fine... WITHIN the WiFi LAN. However, I can't "publish the server" to the MyPlex service, which would have allowed me to access the PMS via 3G/4G on my phone.
I figured out that I need to do my port forwarding, so I got THAT done. And yes, it's done correctly. Yes, both TCP and UDP.
But when I use a port tester, no packets are getting through. Connection timed out.
So I turned OFF the Comodo firewall (set firewall status to disabled), and the port tester works. And the server was "published" correctly.
Turn on the firewall... port tester gets "connection timed out" as if the port's stealthed.
Comodo firewall confirms the "Plex Media Server" is listening on port 32400, which is as it should. But somehow with Comodo firewall on (even in training mode), no packets are getting to it. I've already added "Plex Media Server" to trusted app list, and verified that it has "allow all incoming and outgoing requests" set.
There are NO firewall events in the log. Nada. Zilch. Nothing.
I am stumped.
