IPv6 in Supertuxkart not working
I want to host a Supertuxkart server but Supertuxkart detects no IPv6, so it only sends my IPv4 address which behind CG-NAT and not my IPv6 address. So because of this my server is only listed with my CG-NAT IPv4 in the server list. I forced Dual Stack in the config, which works because i can connect directly via IPv6 but it still sends only the CG-NAT IPv4 address. Does someone now how to fix this. I know that the STUN servers that are used to test IPv6 are actually IPv4 only but i can't change them because Supertuxkart overwrites them.
