use hamachi version 1.0.1.5.
the latest version caused a lot of problems for me and my friends. The network Binding not really stable.

Step 1 - u download hamachi version 1.0.1.5 from filehippo.
Step 2 - Install hamachi and set everything to default. (disable vulnerable .......... make sure u check that)
Step 3 - Make username and password once it tells u to.
Step 4 - Login to hamachi server.
Step 5 - Make network and name it and password it.
Step 6 - Get all your friends to join in to that network. Give em the password for it.
Step 7 - Turn off firewall or whatever antivirus that has firewall.
Step 8 - Open your game and setup on LAN..... he/she should be able to see your game.

Works for warcraft and NFS Most wanted. Havent tried FIFA yet coz no kaki to play with.

If neither of you see the game hosted, there are several reasons. You may then proceed to troubleshoot from the router to the net connection or the game version. You may feel free to pm me if u require any other information.
