Not that I am aware of.

But, in the game you can set up an IP game. When you do this it would require a little communication with your friends.

Roger Wilco, Team Speak or via a messenger program.

Start the game, go to multiplayer and select Host. Give your game a name and a password if you like. Then gife the IP you are using to them. They in turn start their game, hit multiplayer, type in YOUR IP number and hit search. They should all be able to hook up to your game that way.

If you are running a router and or a firewall, that is going to take a lot more specialized setting up of whatever you are using. Here I am lost as I just usually turn my firewall off when I fly online.

Good luck and have fun.
