Howdy! My friend is currently trying to host a Forge-47.3.0 minecraft version 1.20.1 server from his home computer. He is using an IPv6 connection, he's tried a plethera of things to try and get it to work, but a "Network is unreachable: No further information" error always pops up when using the IPv6 address. He can connect to his own server most of the time, but it seems that no one can connect to it outside of his LAN. Help with this issue will be much appreciated!

- What does the server.properties look like?
- Do the people connecting have an public IPv6 address too?
- Does the person hosting it have a public IPv6 address and it allowed through the devices firewall?

The people connecting have IPv4 for the most part, and I believe he does have a public IPv6 address
Let me get the server properties
Polish
People can not connect to a server hosted on IPv6, without too having an IPv6 address

server.properties
Download@Polish People can not connect to a server hosted on IPv6, without too having an IPv6 address
Silky antOP
these are the server properties
there's this too
Polish
yeah, that should be fine and allow connections on IPv6, as long as you have also allowed it through your (ISP and Windows or Linux) firewall
But as noted, the people connecting also need IPv6 to connect
Silky antOP
When he allowed it through the firewall, nothing changed. Also, when he changed from IPv6 to IPv4, it still didn't work
He couldn't connect to his server either when he did that
he's joinin the server now

There's 2 firewalls it would need to be allowed through
And possibly port forwarding depending on how the ISP implements IPv6
(a routed setup should only rely on the devices firewall, but many ISPs still do NAT for IPv6)

Hey, I appreciate the support. I am the one setting up the server on a laptop. My router (Through Verizon) does port fowarding only to IPv4. I even attempted setting my laptop to DMZ host, which should entirely remove firewall, but again, only devices connected to my network could connect

what would be some ways to switch from ipv6 to ipv4 with that in mind?
Silky antOP
He has already tried to change it by disabling ipv6 but it still didn't work

For IPv6, you don't have to do anything based on what he said about not having a port forwarding setting
For ipv4, you'd have to port forward and allow it through the firewall on the router and the end devices firewall
You'd have to change the DNS record if using a domain to only have one or the other (A record to the IPv4 or aaaa to the IPv6 address)
And for IPv4, you'd need to not be behind CGNAT
Shiny Cowbird
good call actually
thanks
Sorry @Shiny Cowbird had to delete it because of the ip
