Host a Valheim server without port forwarding

How it works

The Tunnel connects your server to a relay region near you. Players connect to the relay, and the relay passes the game traffic to your server. Your router needs no open ports, and your home address stays private.

Turn it on

1. When you create the server, choose Tunnel on the Connection step. For an existing server, turn the Tunnel on from its Details tab.
2. Start the server.
3. Send friends the Server Address from the Details tab.

When you need it

• Your internet provider uses CGNAT, so port forwarding can't work.
• You play on Starlink, mobile data or a shared network you don't control.
• You don't want to change router settings or show your home address.

Relay regions and the other games it supports are on the Tunnel page.
