However for ipv4 you specify a netmask while setting up the interface, whereas you do not while setting up the ipv6. I also notice that you list fc02:e::200 for "other end" but in the commands you have fc:02:e::200 which I guess is just typo. Does ifconfig gre6 inet6 fc01:e::100 fc:02:e::200 prefixlen 128 tunnelfib 6 work? Or the whole thing ifconfig gre6 inet6 fc01:e::100 fc02:e::200 tunnel fc01:e::100 fc02:e::200 prefixlen 128 tunnelfib 6 Best regards Andreas _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
