Not working... Don't know why. Here some pastes: --<ifconfig gif0>-- bbs# ifconfig gif0 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 tunnel inet 62.183.165.84 --> 212.224.0.188 inet6 fe80::206:29ff:feb5:5768%gif0 prefixlen 64 scopeid 0x5 inet6 2001:6f8:900:139::2 --> 2001:6f8:900:139::1 prefixlen 128 bbs# --<ifconfig gif0>-- --<ping6 own ip>-- --- 2001:6f8:900:139::2 ping6 statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 0.169/0.203/0.280/0.045 ms --<ping6 own ip>-- --<ping6 sixxs ip>-- --- 2001:6f8:900:139::1 ping6 statistics --- 6 packets transmitted, 0 packets received, 100.0% packet loss --<ping6 other end ip>-- --<ping other end ip4>-- --- 212.224.0.188 ping statistics --- 7 packets transmitted, 7 packets received, 0% packet loss round-trip min/avg/max/stddev = 66.717/106.352/126.935/20.132 ms --<ping other end ip4>-- Can someone give any help with these?

could you post your rc.conf here?

Check your routing, interface and firewalling tables and do a lots of tcpdumps. Also you might want to consider moving to a heartbeat tunnel seeing that your IP changes quite frequently and you are in the negative credits ;)

routing is OK as far as I can see. Firewall is one option. I'm not very familiar with freebsd firewall. :/ My ip is static. I've been trying tunnel with three different NICs (two puters) so that's why different IPs. And I've done everything I can do to get it work. :( My knowledge of networking on *nix is not very professional yet. I hope some could give some help with other setting I might need?

"man ipfw", "ipfw show" and "man tcpdump", eg "tcpdump -i fxp0 proto 41 or host demuc01.sixxs.net" and have fun debugging ;)

and here is paste of whole ifconfig if it helps something: -bash-2.05b$ ifconfig fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::206:29ff:feb5:5768%fxp0 prefixlen 64 scopeid 0x1 inet 62.183.165.84 netmask 0xfffff800 broadcast 62.183.167.255 ether 00:06:29:b5:57:68 media: Ethernet autoselect (10baseT/UTP) status: active rl0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> ether 00:10:a7:0a:1d:55 media: Ethernet autoselect (10baseT/UTP) status: no carrier plip0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 tunnel inet 62.183.165.84 --> 212.224.0.188 inet6 fe80::206:29ff:feb5:5768%gif0 prefixlen 64 scopeid 0x5 inet6 2001:6f8:900:139::2 --> 2001:6f8:900:139::1 prefixlen 128 -bash-2.05b$

These two are the important ones:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::206:29ff:feb5:5768%fxp0 prefixlen 64 scopeid 0x1
inet 62.183.165.84 netmask 0xfffff800 broadcast 62.183.167.255
ether 00:06:29:b5:57:68
media: Ethernet autoselect (10baseT/UTP)
status: active
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 62.183.165.84 --> 212.224.0.188
inet6 fe80::206:29ff:feb5:5768%gif0 prefixlen 64 scopeid 0x5
inet6 2001:6f8:900:139::2 --> 2001:6f8:900:139::1 prefixlen 128
And both seem to be correct... tcpdump is your next best friend...

tcpdump echo on ping6 to pop ipv6: 16:07:54.735518 21-84.adsl.lpoy.dnainternet.fi > tr0.enmuc.de.easynet.net: cl-314.muc-01.de.sixxs.net > gw-314.muc-01.de.sixxs.net: icmp6: echo request lots of that. and then this: 2731 packets received by filter 0 packets dropped by kernel hmm. ipfw show (and ip6fw show) says: ipfw: getsockopt(IP_FW_GET): Protocol not available ip6fw: getsockopt(IPV6_FW_GET): Invalid argument Sorry, but I'm little new to this *nix networking so far. Done everything with NT and OS/2 machines earlier. Trying to move myself into nix world now. :) I'm trying to read manual pages and use google too, but my language is another problem. English is my third language and these texts are sometimes hard to understand.

But do you get anything back? Probably not. It could quite well be that your upstream is filtering proto-41 traffic. Someone on 6to4 is trying to ping you for quite some time now, probably without success...

yes. friend tried from another shell ping. no luck. nothing shown on tcpdump. and traceroute stopped here: 17 tr0.enmuc.de.easynet.net (2001:6f8:800:1003::2) 87.309 ms 91.63 ms 86.413 ms

[fi] Shadow Hawkins on Tuesday, 24 February 2004 17:35:30
hmm. so could it be my isp filtering that? they filter none IPv4 traffic at all. Or my ADSL modem or something...

[fi] Shadow Hawkins on Tuesday, 24 February 2004 17:40:44
and isn't this tunnel all IPv4 traffic between me and pop so I think isp shouldn't filter it anyway.

[fi] Shadow Hawkins on Tuesday, 24 February 2004 17:52:29
So it might be ISP filtering IP Protocol 41 traffic. I have contact them.

[fi] Shadow Hawkins on Tuesday, 24 February 2004 18:02:10
I disabled my tunnel for now until I contact someone at my isp and know for sure if they're are filtering or not. Thank's for all help!
