I've had this problem since the first Gears of War PC patch got out. It keeps telling me that i got a firewall on and therefore are unable to host, even when none is on. It's kinda pissing me off, because 75% of the hosts gives people a horrible ping (Atleast on List Play which is what im playing). Even servers from forexample, the UK, (which is pretty close to my country (Denmark)) sometimes delivers a ping above 500. Pretty annoying, so im trying to find a way to be able to host servers again, because no one was whining about having a high ping, and those i asked never had a ping above 150 (US players too), when i used to be able to host, so its kind of a good deal for everyone. Most me though.
I dont know if i have to open a port in my router, but if i do, how the hell does that work with vista? Doesn't work when i try writing in my IP in the IE/FF address bar.
So.. Yeah.. Any solutions?
