Hi there!
I just tried to host a 1on1 against a friend, but although I opened port 27960, I soon noticed that the COMODO Personal Firewall didn't allow him in - the securty log showed several "High Severity" events with the following details:
Description: Blocked by Protocol Analysis (Fake or Malformed UDP Packet)
Direction: UDP Outgoing
Source: XXX.XXX.XXX.XXX:27960
Destination: XXX.XXX.XXX.XXX:55215
Reason: UDP packet length and the size on the wire (1316 bytes) do not match
Do you have any idea what is causing this? When I disable the protocol analysis module of the firewall, the connection works just fine, so it looks like it must be OA having an issue. It might be just a setting - but it also might be a bug, that's why I posted it here, in "Development".
