Hello, I have succesfully set up a tunnel to my linux router. From the router everything is working fine, i can ping6 ipv6 hosts. I followed the FAQ to give connectivity to my other hosts, so i requested a subnet and followed the instructions from the FAQ. The configuration on the linux router is as following: ifconfig: eth1 Link encap:Ethernet HWaddr 00:01:02:F2:FD:36 inet addr:192.168.1.51 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: 2001:610:65f:1::1/64 Scope:Global inet6 addr: fe80::201:2ff:fef2:fd36/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4452489 errors:12 dropped:0 overruns:1 frame:12 TX packets:5518567 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3017185228 (2.8 GiB) TX bytes:3798092130 (3.5 GiB) Interrupt:217 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:29700 errors:0 dropped:0 overruns:0 frame:0 TX packets:29700 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:19580738 (18.6 MiB) TX bytes:19580738 (18.6 MiB) sixxs Link encap:IPv6-in-IPv4 inet6 addr: 2001:610:600:425::2/64 Scope:Global inet6 addr: fe80::c0a8:133/64 Scope:Link UP POINTOPOINT RUNNING NOARP MTU:1280 Metric:1 RX packets:368 errors:0 dropped:0 overruns:0 frame:0 TX packets:498 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:56867 (55.5 KiB) TX bytes:49361 (48.2 KiB) [ arnold@:/etc/init.d ] cat /etc/radvd.conf interface eth1 { AdvSendAdvert on; MinRtrAdvInterval 3; MaxRtrAdvInterval 10; AdvDefaultPreference high; AdvHomeAgentFlag off; prefix 2001:610:65f:1::/64 { AdvOnLink on; AdvAutonomous on; AdvRouterAddr on; }; }; The other hosts on my LAN are receiving an ipv6 adress, and are able to ping to the linux router @ 2001:610:600:425::2 PING 2001:610:600:425::2(2001:610:600:425::2) 56 data bytes 64 bytes from 2001:610:600:425::2: icmp_seq=1 ttl=64 time=4.21 ms 64 bytes from 2001:610:600:425::2: icmp_seq=2 ttl=64 time=0.314 ms But they can't ping to the ipv6 internet! When i try to ping6 www.sixxs.net or my POP (=2001:610:600:425::1) i won't get any response. I assume there must be a routing issue somewhere on my linux router, or there is something going wrong at the POP. I hope sixxs can help me resolve this issue. Kind regards, Arnold
