Strange traceroute results
![]()
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

Strange traceroute results
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.
