Wurm Unlimited LAN but Not Internet: Server Browser Troubleshooting

Wurm Unlimited Guide • Updated Aug 22, 2026

Wurm Unlimited Visible on LAN but Not Internet

LAN visibility proves that the server process and local client can communicate. It does not prove that Steam query traffic or the public client port can reach the host.

Check the public path

  1. Confirm the server’s external IP is public and correct.
  2. Check externalport and queryport.
  3. Allow the client port and Steam query range through the firewall.
  4. Forward ports to the machine running the selected game database.
  5. Refresh the Internet tab and try direct connection.

Do not expose RMI while diagnosing browser visibility. The player path and the administration path are separate.

For exact port roles, see Wurm server ports and managed Wurm hosting.
