I've looked everywhere and havent found a solution, please dont lock this. when i play live on halo, i can usually join games and stuff, but when it comes to parties and game invites it will say "your nat is set to strict" or something like that when in fact its open. I've looked for solutions and all i really found was to put universal plug n play on in my router but it was already on. I've seen portforwarding and changing ip adresses manually, but i can not confirm that which is why im asking here. Does anyone have an idea on what to do and can walk me through?
