Sven Co-op Ports & Protocols
| Port | Protocol | Purpose |
|---|---|---|
| 27015 | UDP | Game traffic, custom content transfers and RCON all share this single UDP port |
| 26900 | UDP | Valve anti-cheat (VAC) service traffic. 26900 is only the start value: if it is taken the server auto-increments to the next available port |
| 27005 | UDP | The Steam client communication port. The official port table does not list it; only LinuxGSM passes it explicitly, so this site marks it optional |
