Unfamiliar firewall restrictions on a Minecraft server
Unfamiliar firewall restrictions on a Minecraft server
You're facing access issues with your Minecraft server setup. Besides Windows Defender, common firewalls to consider disabling include Windows Firewall, third-party antivirus solutions, and network-level security tools. Ensure you check both local and global settings for restrictions.
I'm checking if your ISP is restricting certain ports. Could you clarify the router settings, such as port forwarding rules or any access restrictions you've set up?
I can access port 11169 exclusively, while others receive "No route to host" messages.
They are providing their 192.168.0.x network address or their real public IP.
Port 25565 is being redirected to port 11169 for external access. Users should use port 25565 instead of 11169. Public IP addresses should be used for connectivity, not private internal ones like 192.168.x.x. It’s unnecessary to block these internal IPs because they’re not reachable from outside and ISPs typically don’t send traffic to them.
I adjusted the server's port to 11169 myself. I also modified the forward port to 25565 in both directions, yet the connection using {publicIP}:11169 fails. They are now encountering a timeout error.
The screenshots indicate forwarding port 25565 to port 11169. This means users need to access port 25565, not 11169. The server should be set to listen on port 11169. [public-ip]:25565 —> [internal-ip]:11169
Server port is back at 25565. Forwarding remains at 25565 in both directions. Connection issues persist. No apparent firewall blocking it, though I’ve disabled Windows Defender and haven’t altered any settings shown. Previously trying dynamic IP caused router failure and required a reset.
