I currently have port 8080 open (UDP) on my firewall. I can get to the lobby, but online missions won't start (regular or campaign, can't connect to server).
Are there any other known ports I need to open up for DIF (and are they UDP or TCP)?
I notice some traffic on 2234 and 2308 whenever I try. I tried to find some documentation on what ports DIF needs opened but struck out. I apologize if this is documented somewhere and I missed it...
