All, I've got a question about the IPv6 loopback address inside a jail. I've got a bunch of jails configured with both IPv4 and IPv6 addresses all of which are tied to a physical interface (em0). When I'm inside the jail I can ping 127.0.0.1 without any problems: root@imap:~#ping 127.0.0.1 PING 127.0.0.1 (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.031 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.049 ms ^C A ping6 to ::1 however returns: root@imap:~#ping6 ::1 PING6(56=40+8+8 bytes) 2001:1af8:fe30::26 --> ::1 ping6: sendmsg: Can't assign requested address ping6: wrote ::1 16 chars, ret=-1 ^C When I configure the IPv6 address used by the jail on the loopback interface (lo0) things magically start working: root@test:~#ping6 ::1 PING6(56=40+8+8 bytes) 2001:1af8:fe30::36 --> ::1 16 bytes from 2001:1af8:fe30::36, icmp_seq=0 hlim=64 time=0.092 ms ^C My question; is this supposed to work like this because it feels a bit inconsistent, I could migrate the IPv6 addresses to the loopback interface but prefer to have them directly connected on the LAN. Thanks for any insight! Rob Evers P.S. I can supply any further information needed. -- If we don't believe in free expression for people we despise, we don't believe in it at all.
