I'm a friend of MagicSlayer, and I heard that someone needed help port forwarding a minecraft server. There are a few things you need to know to port forward.

1. Your Computer IP Address. This can be found via command prompt by typing the command "ipconfig"

2. Make sure that in your minecraft server.properties options, the important things that should be set is the server port and server ip. Server port should be 25565 and the ip should be left blank.

Next: Open your router address page (usually located at 10.0.0.1, routerlogin.net, 169.168.0.1, just google it). Find the port forward option, sometimes located under advanced configuration. You'll need the options to be configured something similar as followed, but replace server IPv4 and IPv6 with your IPv4 and IPv6. If you do not see an IPv6 field, do not worry as this is optional on some routers.
