How to host a IP game with a router?

I can connect to a game using a router.... but cannot create one and have a successful connection.

Anyone know which ports I need to open and how?

I have a D-Link DI-714P+ if anyone is using the same or similar router.

Thanks!

At the end of the readme file you will find a list of ports to open for your router.

UDP Port#: 3658 is the only one you need to open to be able to host games on EASO and direct IP.
