Im trying to host a server so my friends and family can all play together and i have a BIG problem ....
No one outside of my lan can connect to my server, i have spent 3 days going through all the posts, making changes to the firewalls ect and they still cant get into the server, game freezes up on them when they press connect.......
I have gone through the fix for win vista/dual core ect and nothing changes, they can connect to other servers but not mine so im sure its something i have not done.

PLEASE help

Thank you kindly in anticipation of all your help
