I have recently created a minecraft server and wanted to allow other people to join. I am able to join just fine through my LAN, but I cannot connect using the external ip. I felt for sure that I had forwarded it correctly, however it is not working. I’m attempting this using the Cisco DPC3941T Xfinity Router just in case that matters. I’ve also checked to make sure the port was open using http://www.ipfingerprints.com/portscan.php, and I’ve checked to see if the firewall was blocking it. I’m not too positive if it is or isn’t, so hopefully someone can help me.
