Check if your Unturned server is online
Unturned answers Steam queries on a port calculated from its game port, which trips up anyone who forwards only the number from the config.
The ports Unturned uses
It uses a short block of consecutive UDP ports beginning at the configured game port, and the query comes back from one of the higher ports, not the base one. Forward a single port and you have a server that can be joined directly and seen nowhere else.
Every port a default Unturned install uses
With the game port left at 27015. If you changed it with Port in Config.json, the other ports move with it.
| Port | What it is for |
|---|---|
| 27015 UDP | Game trafficRequired Port. |
| 27016 UDP | QueryRequired Unturned takes the two ports above the one you set. All three must be open. |
| 27017 UDP | SteamRequired The third of the block. |
Still offline? Try this
Forward the full range, not a lone port. Still failing? See whether the server was launched in LAN mode rather than internet mode; in LAN mode it never replies to outside queries, no matter what the router is doing.
What a Unturned server needs to run well
- Memory, 12 players
- 4 GB
- CPU cores
- 2+
- Disk
- 10 GB+
Unity, and light for its genre. Curated workshop maps raise both memory and load time.
