Was.

Try it from various source addresses on the router. Disabling the firewall for ipv6 is sometimes helpful also, for debugging. You might also want a reqprefix of 56 in the wan stanza. We did not have much chance to test against any other prefix sizes than 64, 60, and 48. > root@centaur:/etc/network# ping6 ipv6.google.com > PING ipv6.google.com(lhr25s02-in-x200e.1e100.net) 56 data bytes > From lhr25s02-in-x200e.1e100.net icmp_seq=1 Destination unreachable: No > route > From lhr25s02-in-x200e.1e100.net icmp_seq=2 Destination unreachable: No > route > From lhr25s02-in-x200e.1e100.net icmp_seq=3 Destination unreachable: No > route > From lhr25s02-in-x200e.1e100.net icmp_seq=4 Destination unreachable: No > route > ^C > --- ipv6.google.com ping statistics --- > 4 packets transmitted, 0 received, +4 errors, 100% packet loss, time > 3024ms > > For your information, ipv6 routes on centaur are: > root@centaur:/etc/network# ip -6 route > 20xx:xxxx:xx55:ae10::f48 dev eth0 proto kernel metric 256 expires > 84847sec pref medium > 20xx:xxxx:xx55:ae10::/64 dev eth0 proto ra metric 100 pref medium > 20xx:xxxx:xx55:ae00::/56 via fe80::2cb0:5dff:fea6:94ad dev eth0 proto ra > metric 100 pref medium > fe80::/64 dev eth0 proto kernel metric 256 pref medium > default via fe80::2cb0:5dff:fea6:94ad dev eth0 proto static metric 100 > pref medium > > and on the router are: > root@cerowrt:~# ip -6 route > default from :: via fe80::f60f:1bff:fe17:8d00 dev pppoe-ge00 proto static > metric 1024 > default from 20:xx:xxxx:xx00:55ae::/64 via fe80::f60f:1bff:fe17:8d00 dev > pppoe-ge00 proto static metric 1024 you should also have had a default from 20xx:xxxx:xx55:ae00::/56 I think. ip -6 route add default from > 20xx:xxxx:xx55:ae00::/64 dev gw00 proto kernel metric 256 > 20xx:xxxx:xx55:ae01::/64 dev gw10 proto kernel metric 256 > 20xx:xxxx:xx55:ae02::/64 dev sw00 proto kernel metric 256 > 20xx:xxxx:xx55:ae03::/64 dev sw10 proto kernel metric 256 > 20xx:xxxx:xx55:ae10::/60 dev se00 proto kernel metric 256 This appears wrong to me in that ae10 should have been a /64 > unreachable 20xx:xxxx:xx55:ae00::/56 dev lo proto static metric > 2147483647 error -128 > fe80::/64 dev se00 proto kernel metric 256 > fe80::/64 dev ifb0 proto kernel metric 256 > fe80::/64 dev sw10 proto kernel metric 256 > fe80::/64 dev sw00 proto kernel metric 256 > fe80::/64 dev gw10 proto kernel metric 256 > fe80::/64 dev gw00 proto kernel metric 256 > fe80::/64 dev ge00 proto kernel metric 256 > fe80::/10 dev pppoe-ge00 metric 1 > fe80::/10 dev pppoe-ge00 proto kernel metric 256 > > I'm stumped.
