How to config IP Forwading:(

Alright so first go into your pc’s firewall, then open the port needed.
Then after that if you want others to be able to join, enter cmd, type “ipconfig” and copy default gateway.
Then visit that ip in your browser most likely, and port forward to your computer, oh and also, you get your ip in that one, I believe, unless windows 8 removed that
