IPv6 Problems, possibly an issue with loopback device

[DeanB]

Hi all,

I'm having a bit of trouble with my ipv6 setup. I've successfully used it on several distributions, including gentoo. But last night, for some reason, it broke. I've had several suggestions about lo having no link-layer address but it was never configured with one to begin with.

Here's my results from ping6:

PING www.kame.net(2001:200:0:4819:203:47ff:fea5:3085) 56 data bytes
From ::1 icmp_seq=2 Destination unreachable: Address unreachable
From ::1 icmp_seq=3 Destination unreachable: Address unreachable
From ::1 icmp_seq=4 Destination unreachable: Address unreachable
From ::1 icmp_seq=5 Destination unreachable: Address unreachable
From ::1 icmp_seq=6 Destination unreachable: Address unreachable

--- www.kame.net ping statistics ---
6 packets transmitted, 0 received, +5 errors, 100% packet loss, time 5033ms

And here's the captured packets on lo and my external ethernet card:

eth0:

lo:
23:32:18.020586 ::1 > bitch.bang-me.net: [|icmp6]
23:32:19.028042 ::1 > bitch.bang-me.net: [|icmp6]

23:32:22.043030 ::1 > bitch.bang-me.net: [|icmp6]

I also have a routing entry from 2000::/3 to my tunnel device. Any ideas?

Thanks in advance.
