Thanks for the quick response.
The IP that I am putting in should look something like this 192.168.x.x ? The problem is, this address changes every time I restart internet. It doesn't change the whole address, just the last number.
If you mean my public IP address, that also changes every time I restart internet because it's a dynamic IP address.
Sorry if this all sounds stupid, I just want to play the game with my friend and in order to achieve that I want to do this right, so I know if it actually works or not.
Again, thanks for you patience!
