How to set the query port in Rust

Arguments

portRequired

UDP port for server browser queries.

What it does

The server browser contacts this port to read your name, player count and other details. If it is blocked, the server can still be joined by address but may not appear in the browser. Set it on the launch line and open it for UDP in your firewall.

The game's own description: UDP port used for Steam server browser queries; uses the game port if set to 0

Good to know

• Launch-line setting.

Run it on your server

Type it in the server console or send it over RCON; admins can also use the F1 console in game. To keep a setting, run server.writecfg after changing it, or put it on the launch line as +name value.
