Hi all. I got my tunnel approved so immediately tried to set up the stuff but I am running into troubles. My Debian machine is behind a WRT54G router, to try things out I just put the Debian box in the DMZ since I was fairly certain that would work. I edited the aiccu.conf and when starting aiccu I got the sixxs tunnel. When trying to ping the pop I get: natoma:~# ping6 2001:960:2:42f::1 PING 2001:960:2:42f::1(2001:960:2:42f::1) 56 data bytes From ::1 icmp_seq=1 Destination unreachable: Address unreachable From ::1 icmp_seq=2 Destination unreachable: Address unreachable When I ping my own address I do get replies: natoma:~# ping6 2001:960:2:42f::2 PING 2001:960:2:42f::2(2001:960:2:42f::2) 56 data bytes 64 bytes from 2001:960:2:42f::2: icmp_seq=1 ttl=64 time=0.088 ms 64 bytes from 2001:960:2:42f::2: icmp_seq=2 ttl=64 time=0.056 ms I also set up iptables to log (and also accept) the proto 41 packets and I can see packets coming in so there is some traffic by the looks of it. I am a bit lost whether there maybe is a routing issue so just for clearness some more info, if anybody can give me some info that will be greatly appreciated. I have requested a tunnel with the endpoint being my ADSL wan ip, this is natted to the Debian machine, do I have to change this to the internal (192.168.X.X) ip? natoma:~# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:50:8B:5A:E5:E5 inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::250:8bff:fe5a:e5e5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:8175 errors:0 dropped:0 overruns:0 frame:0 TX packets:5169 errors:0 dropped:0 overruns:0 carrier:0 collisions:5 txqueuelen:1000 RX bytes:2733094 (2.6 MiB) TX bytes:891349 (870.4 KiB) Interrupt:11 Base address:0x8000 eth1 Link encap:Ethernet HWaddr 00:A0:C9:2F:6C:CA BROADCAST MULTICAST MTU:1500 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:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:9 Base address:0x8000 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:899 errors:0 dropped:0 overruns:0 frame:0 TX packets:899 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:153438 (149.8 KiB) TX bytes:153438 (149.8 KiB) sit0 Link encap:IPv6-in-IPv4 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) sixxs Link encap:IPv6-in-IPv4 inet6 addr: 2001:960:2:42f::2/64 Scope:Global inet6 addr: fe80::52a1:abbc/128 Scope:Link UP POINTOPOINT RUNNING NOARP MTU:1280 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:2 dropped:0 overruns:0 carrier:2 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) natoma:~# ip -6 route 2001:960:2:42f::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 metric10 64 fe80::/64 dev eth0 metric 256 mtu 1500 advmss 1220 metric10 64 fe80::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 metric10 64 ff00::/8 dev eth0 metric 256 mtu 1500 advmss 1220 metric10 1 ff00::/8 dev sixxs metric 256 mtu 1280 advmss 1220 metric10 1 default via 2001:960:2:42f::1 dev sixxs metric 1024 mtu 1280 advmss 1220 metric10 64 natoma:~# uname -a Linux natoma 2.6.9-1-686 #1 Thu Nov 25 03:48:29 EST 2004 i686 GNU/Linux
