Configuring Battle.net for Warcraft

Please help - have recently installed Comodo, and my teen is now having trouble getting into Battle.net to play Warcraft online.
I can’t seem to figure out how to get the firewall to allow access - we are not getting any alerts, just when we choose the online game we want to join, the system freezes up , and we did not have this issue before installing Comodo.
I am hopeful someone out there can assist me in ‘configuring’ this out!!

Thanks to all!

I’m assuming you’re talking about WarCraft III… don’t know if anyone even play II anymore. Anyway, you will need to open the following ports.

Allow port 6112 TCP out and allow established sessions in
Allow port 6112 TCP in (hosting custom games)
Allow port 6113-6119 TCP out and in (hosting custom games if you’ve changed the default port in the Options/Gameplay screen)
