So far, i do not know how to use Fedora's scripts to setup ipv6, but i did it manually, basicly i made a script which does the following: ip tunnel add sixxs mode sit local [SERVER_IPV4] remote [POP_IPV4] ip link set sixxs up ip link set mtu 1280 dev sixxs ip tunnel change sixxs ttl 64 ip -6 addr add [SERVER_IPV6]/[PREFIX_LENGTH] dev sixxs ip -6 ro add default via [POP_IPV6] dev sixxs ifconfig sixxs add [ADDITIONAL ADDRESSES] Hopefully this helps someone :)
