Sorry if this has been discussed in the main thread but there are a lot of posts to plough through!! 
I set up a custom gp with a mate on Saturday and all worked fine but when we came to have another go last night we couldnt connect!?!?
We can connect to some listed games (and not others!) but it simply will not let one connnect to the other in a private game!
My mate reset his router in the meantime but he's gone back on and re-added the Steam ports etc so we cant figure out what has changed - or is this a common, random problem????
Thanks for any advice coz this is driving me insane!!!!
