Once you get into your router configuration you’ll want to forward ports to the computer where the server is running. You’ll need the internal IP address of that computer. You can get the IP address by right clicking Start and clicking Command Prompt. When the Command Prompt window opens type in ipconfig and hit enter. Look for the IPv4 Address. Usually it’ll look like 192.168.1.2 or something similar.
You need to open port 28000 TCP and UDP and port 28001 also TCP and UDP.
