Hi. Last week i had to update my aiccu running on my linksys wrt router because the old version i was using was rejected by the server. since then i noticed strange traceroute behavior like this traceroute6 to www.sixxs.net: fadenb@hayami:~$ traceroute6 www.sixxs.net traceroute to noc.sixxs.net (2001:838:1:1:210:dcff:fe20:7c7c) from 2001:6f8:139d:0:217:31ff:fe94:d706, 30 hops max, 16 byte packets 1 2001:6f8:139d:: (2001:6f8:139d::) 0.493 ms 0.49 ms 0.434 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 so-0-0-0.dus11.ip6.tiscali.net (2001:668:0:2::1:1) 45.534 ms 43.689 ms 46.938 ms 10 so-0-0-0.ams22.ip6.tiscali.net (2001:668:0:2::1:122) 151.272 ms 79.576 ms 65.711 ms 11 so-6-0-0.ams11.ip6.tiscali.net (2001:668:0:2::1:271) 54.73 ms 54.274 ms 53.682 ms 12 ge6-2-0.br0.ams3.nl.gbxs.net (2001:7f8:1::a500:9009:1) 56.155 ms 56.114 ms 57.148 ms 13 ams-ix.ipv6.concepts.nl (2001:7f8:1::a501:2871:1) 54.456 ms 98.425 ms 54.204 ms 14 se1.breda.ipv6.concepts-ict.net (2001:838:0:10::2) 71.468 ms 56.905 ms 81.692 ms 15 noc.sixxs.net (2001:838:1:1:210:dcff:fe20:7c7c) 96.84 ms 73.871 ms 96.903 ms fadenb@hayami:~$ traceroute6 to 2001:6f8:900:4f2::1 my pop ipv6: traceroute to 2001:6f8:900:4f2::1 (2001:6f8:900:4f2::1) from 2001:6f8:139d:0:217:31ff:fe94:d706, 30 hops max, 16 byte packets 1 2001:6f8:139d:: (2001:6f8:139d::) 0.477 ms 0.539 ms 0.437 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 gw-1267.ham-01.de.sixxs.net (2001:6f8:900:4f2::1) 37.133 ms 28.117 ms 27.761 ms fadenb@hayami:~$ output of ip -6 route on my router: ~ # ip -6 route 2001:6f8:900:4f2::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 2001:6f8:139d::/64 dev br0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev eth0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev eth1 metric 256 mtu 1500 advmss 1220 fe80::/64 dev vlan0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev br0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev vlan1 metric 256 mtu 1500 advmss 1220 fe80::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 ff00::/8 dev eth0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev eth1 metric 256 mtu 1500 advmss 1220 ff00::/8 dev vlan0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev br0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev vlan1 metric 256 mtu 1500 advmss 1220 ff00::/8 dev sixxs metric 256 mtu 1280 advmss 1220 default via 2001:6f8:900:4f2::1 dev sixxs metric 1024 mtu 1280 advmss 1220 ~ # please advise me what is going wrong.

Check the TTL of the tunnel interface ("ip tun sho"). The TTL should be '64' and not 'inherit'. Also you might want to add a "ip ro add 2001:6f8:139d::/48 dev lo" somewhere. Of course, next to that read "Reporting Problems" part on the Contact page.
