Yo,

Guess I'll get to the problem straight away; I can't seem to join any online game or host any online game whenever other players are involved. I am able to host my own game, play with PC enemies and simply play the game. But once I try to join a game made by some friends of me or when I try to host a game and others try to join it, they can't.

When joining another players game:

- The connect windows comes up with all the players connecting / already in the room and all names appear yellow.

- The message comes up stating "Impulse attempting NAT negotation..." (or something close to this, I hope you know which one I mean)

- Eventually it states "Impulse failed to set up NAT connection" (or something close to that) and everything simply stops, sometimes some of the other names turn green and the host turns red, my own name remaining yellow.

When trying to host my own game for other players:

- I myself enter the room where I can setup the map etc. but the other players can't seem to connect and can't get passed the "Impulse Attempting NAT ..." message.

What I've tried/What problems I had before:

- In the beginning I constantly got the message when I tried to join another players game "Failed to join game" -> Solved this by opening ports on my router (6070 - 6080) -> After that I could get passed that but ran into the problems stated above.

- I've added both Impulse and the Demigod Application to the windows firewall exception list (but even turning the firewall off doesn't seem to solve the NAT problem)

I'm currently using Windows Vista Ultimate 64-bit OS, with an Nvidia GTX 260 card, the complete PC is little over 4 months old now.

I've looked arround a bit and couldn't find much on this though, but maybe I have looked at the wrong places, I'm kinda new to this (game) etc, so any information or help on this problem is highly appreciated ^^
