Me and my friend want to play together on a Minecraft server. However, he would like to host server on his own PC. As you know, since the port in the firewall, as well as. Open in the Fritzbox. He did that too. Nevertheless, I can't join the server. In server.properties, the Severport has remained on the default value and the ServerIP has not been set, ie empty. I join his external IP. With me are also all ports, etc. Open
I would be very happy about an answer. By the way: My friend can join my server, which I host on my PC.
Ever thank you in advance
As you describe it, it seems right. The only point that occurred to me: It could also be due to its Internet provider. If it uses only DS-Lite, IPv4 access from the outside to its router is not possible because multiple customers share an IPv4 address. This is done, for example, by Kabel Deutschland (as well as others) because they do not have enough IPv4 addresses for all customers. You could ever try an IPv6 port release (if an appropriate IP is assigned).
What do you mean, IPv6 port sharing. I do not know anything about this area at all. I'm programming everything for Minecraft, but I do not know enough about that
IPv6 addresses are most often represented as up to 8 with: separate blocks of up to 4 hexadecimal numbers each (e.g., fe80 :: 35e4: 9f48: 6861: 951). But they are not to be confused with the MAC addresses. IPv4 addresses, on the other hand, are usually represented by 4 numbers separated by periods from 0 to 255 and are what is often understood by IP.
If you get assigned an IPv6 address from the Internet provider and distribute IPv6 addresses in the network, you can set up port forwarding here, just like with IPv4 (if the router supports it).
