Hello all, Before a reboot of my router luna, everything worked allright with the tunnel. After a reboot, i thought i setted up the tunnel the same as before the reboot, but i keep get messages: From ::1 icmp_seq=1 Destination unreachable: Address unreachable I can't reach the IPv6 POP :\ root@luna:~# modprobe ipv6 ; ifconfig sit0 down ; ifconfig sit1 down ; ifconfig sit0 up ; ifconfig sit0 tunnel ::213.197.27.252 ; ifconfig sit1 up ; ifconfig sit1 add 2001:838:300:116::2/64 ; route -A inet6 add 2000::/3 gw 2001:838:300:116::1 dev sit1 POP IPv4 213.197.27.252 IPv6 Prefix 2001:838:300:116::1/64 POP IPv6 2001:838:300:116::1 Your IPv6 2001:838:300:116::2 What am I doing wrong? Running on Slackware 8.1 ; and i'm sure ipv6 modules are good. It worked before a reboot :\ Edit: ifconfig output: sit0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet6 addr: ::<external ipv4>/96 Scope:Compat inet6 addr: ::127.0.0.1/96 Scope:Unknown inet6 addr: ::192.168.0.1/96 Scope:Compat UP RUNNING NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) sit1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet6 addr: fe80::5038:b6fb/10 Scope:Link inet6 addr: 2001:838:300:116::2/64 Scope:Global inet6 addr: fe80::c0a8:1/10 Scope:Link UP POINTOPOINT RUNNING NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:1100 (1.0 Kb)
