Setting Up a Port Forward for Atlas Server

You might need to forward some ports in your router when you use Atlas Server. A port forward allows incoming connection requests from the internet to go straight to Atlas Server.
Routers do not generally allow incoming connection requests from the internet. A port forward can overcome this limitation.

- The IP address of your router.
- The IP address of your computer.
- A list of TCP and UDP ports that need to be forwarded.
