To get Tribes 2 able to play IP to IP, unpack this archive to your root game
directory, and run ip2ip.bat, it will clean a few things and modify a script
file. Now run "Tribes 2 Solo & LAN.bat" and go to the LAN tab, a new button
should have appeared : 'FILTER'. Click on filter, and in the field for filter
name, just put IP of the server you want to play with, save and refresh 
servers list : now you can connect and play over internet :)

Please note that you can play only if you're running the SAME version !
Playing between iso version and rip version is not possible !

Greetings to our friend for this GREAT cheat :) Keep up the good work !
