What Port Does Unturned Use?

Unturned is a popular sandbox survival game developed by Nelson Sexton. It offers a unique blend of crafting, exploration, and survival in a post-apocalyptic world. As with any online multiplayer game, it is crucial to understand the technical aspects, including the port it uses for communication.

Unturned primarily uses the Universal Plug and Play (UPnP) protocol to establish connections between players. UPnP allows devices on a network to discover each other and establish communication without any manual configuration. This protocol enables seamless gameplay and removes the need for players to manually forward ports on their routers.

The default port used by Unturned for client-server communication is UDP 27015. UDP, or User Datagram Protocol, is a connectionless protocol that provides fast and efficient data transmission. It is commonly used in online gaming to ensure minimal latency and smooth gameplay.


1. Can I change the default port in Unturned?
Yes, you can change the default port by modifying the server configuration file. Open the “Commands.dat” file and locate the line that says “Port 27015”. Change the value to your desired port and save the file.

2. Do I need to open the UDP 27015 port on my router for Unturned?
If you have UPnP enabled on your router, it will automatically handle the port forwarding for you. However, if UPnP is disabled, you need to manually forward the UDP 27015 port to your computer’s local IP address.

3. Why is my server not accessible to other players?
Ensure that your firewall settings allow Unturned to communicate through UDP 27015. Additionally, make sure UPnP is enabled on your router or manually forward the port if necessary.

4. Can I play Unturned without port forwarding?
Yes, you can play Unturned without port forwarding if UPnP is enabled on your router. It automatically handles the port forwarding process for you.

5. Can I use a different port for LAN multiplayer?
Yes, you can change the port for LAN multiplayer by modifying the server configuration file on the host computer. All players connecting to the LAN game must use the same port.

6. Does Unturned use TCP for communication?
No, Unturned primarily uses UDP for client-server communication. TCP is a connection-oriented protocol, whereas UDP provides faster, connectionless data transmission, which is essential for online gaming.

7. Can I host a dedicated server on a different port?
Yes, you can host a dedicated Unturned server on a different port. Modify the server configuration file to change the port value, and ensure the necessary port forwarding or UPnP settings are adjusted accordingly.
