If the ports are forwarded and the external clients are using the right external IP and ports…then something is still blocking the traffic :unamused:. Check these:

  1. Double-NAT Issue: If you’re using both a modem and a router, your router might be in a private network itself. In this case, you’ll need to set the modem to bridge mode.

  2. ISP Blocking Ports: Some ISPs block certain inbound traffic. Reach out to your ISP and confirm they’re not messing with your ports (especially the game ones like 2456-2457).

Check these out, and we’ll dig deeper if needed—it’s like peeling a really annoying onion! :onion:
