This guide shows how to open a TCP port on your router so friends can join over the internet.
!!! tip "You may not need this at all"
Port forwarding is only for [direct connections](direct-connection.md) over the
internet.
- [Steam Relay](steam-relay.md) needs no port and no router setup at all.
- On the same network nothing has to be forwarded either.
- When hosting starts, the mod already asks your router to open the port itself. Only
follow this guide if the hosting status asks you to forward it manually.
The default port is TCP `25001`. The host, every joining player, the firewall rule and
the router rule all have to use the same port.
