My provider at the moment is Telstra, so I typed in the gateway IP and went into the Port Forward section. I typed in the Minecraft port which by default should be 25565, then for my Internal IP I put my IPv4, and for External I left it as, 'Any'. I am using also TCP - UDP. With all this said, my friends still cannot join my server, using the address from ipchicken.com. My Windows Firewall is turned OFF. Does it matter if there are already services using my IPv4? I don't really know but I would greatly appreciate if somebody could help me with this, I have been trying for a few days but cannot seem to get it working.
