UDP 28015
Synopsis
- Rust (Facepunch Studios) dedicated servers use UDP port 28015 by default for gameplay traffic and the Steam A2S server query; this is the standard setting in Rust server configs and hosting guides.
- Real-world examples include community and official Rust servers hosted by providers such as Nitrado and GameServers.com, which require UDP 28015 to be open for connectivity and server-browser visibility.
- This port is often targeted in DDoS and reflection/amplification attacks abusing the Steam query (A2S) UDP traffic directed at Rust servers.
