Title: COMODO Personal Firewall: "Fake or Malformed UDP Packet" Post by: ThomasR on September 07, 2007, 02:11:34 PM 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: Quote 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".

http://forums.comodo.com/help/netgear_network_storage_is_blocked-t9329.0.html Looks like they recommended that you turn the function off. EDIT: Also it would be an engine problem and out of our scope.
