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.
W/O actually connecting, simply adding your IP (73.203.151.125) to my minecraftclient, I can see your server is up and available (two users connected). Testing the connection my ciient connects (and kicks me out due to whitelisting, good ).
As far as I can see your server is up and running, and available.
Just a heads up, in some cases, routers may have a function or feature enabled called Filter WAN NAT Redirection or something along those lines which will basically not allow you to use your Public IP from within your LAN; it can typically be located or found under Security and/or Firewall (or something else along those lines) and would likely be the reason why you are unable to do anything having to do with your Public IP from within your LAN.
