i cant seem to find my firewall/router at all so i cant change the ports so players can come into my server. How can i find my firewall/router?

It should be a couple feet away from your computer. It's a box with blinking lights and it's usually labeled "router."

To adjust your router settings, type in "192.168.0.1" and get the password from your router manual.

http://192.168.0.1
http://192.168.2.1
