I have searched and searched, all the info I have found does not work. Has anyone found a way to get the Battle.net app and WOW to function and/or log in using Sophos UTM 9.2?
Took me all night but I got it to work. Create service definitions for ports 1119, 1120, 3724, 4000, 6112, 6113, 6114, 6881:6999, 8086, 8087, 9081, 9090, 9097, & 9100, all TCP/UDP then make a service definition group for all listed ports. I named mine wow ports. Make a new firewall rule as followed.
For your own home, you will face a lot of work trying to manually open up all outgoing ports to various online services. You might consider a broader rule allowance ifyou dont need to be completely locked down. (Incoming DNAT rules of course are needed for forwarding ports internal) but you might have more global luck (and save many hours) via a simple Internal (Network) --> Any Service-->Any destination = allow.
I just tried wow and it seems to work fine in all regards. Are you using the web proxy/filtering at all? Do you get entries for blocked actions when trying to play wow?
What about application control? is that one and by chance blocking the Warcraft pattern?
So to be sure, you are running otherwise under a full "internal (network)" (not internal interface or something else right? -> any service --> any destination = allow rule?
And you have setup Internal (NetworK) -> External or Internet (interface) masquerading?
