FreeBSD 7.1 IPv6 problem
« on: February 17, 2009, 01:22:39 PM »

Hey,

so i made it as it was in scripts, interface seems to be ok same with routing table. I've checked few PoPs but it still doesnt work at all, so any advices?

conf:
Code: [Select]
ifconfig gif1 create
ifconfig gif1 tunnel 89.76.108.102 216.66.80.30
ifconfig gif1 inet6 2001:470:1f0a:1390::2 2001:470:1f0a:1390::1 prefixlen 128
route -n add -inet6 default 2001:470:1f0a:1390::1

interface:

Code: [Select]
gif1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
        tunnel inet 89.76.108.102 --> 216.66.80.30
        inet6 2001:470:1f0a:1390::2 --> 2001:470:1f0a:1390::1 prefixlen 128
        inet6 fe80::21f:c6ff:fe32:3f46%gif1 prefixlen 64 scopeid 0x7

routing table:

Code: [Select]
Internet6:
Destination                       Gateway                       Flags      Netif Expire
::/96                              ::1                                UGRS      lo0 =>
default                           2001:470:1f0a:1390::1      UGS      gif1
::1                                ::1                                 UHL       lo0
::ffff:0.0.0.0/96               ::1                                UGRS     lo0
2001:470:1f0a:1390::1     link#7                            UHL        gif1
2001:470:1f0a:1390::2     link#7                            UHL        lo0

ping6:

Code: [Select]
>> ping6 he.net
PING6(56=40+8+8 bytes) 2001:470:1f0a:1390::2 --> 2001:470:0:76::2
ping6: sendmsg: Network is unreachable
ping6: wrote he.net 16 chars, ret=-1
^C
--- he.net ping6 statistics ---
1 packets transmitted, 0 packets received, 100.0% packet loss

Thx.

Make sure you are using the correct IPv6 information. What you have in this forums post isn't what your tunnel is currently configured for. 2001:470:1f0a:139e::/64 should be your point-to-point prefix.

Yes Sir,
i just checked with other ISP and forgot to use simple ipv4 change, but all the time i used script provided on site still nothing...

Code: [Select]
gif1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
        tunnel inet 89.76.108.102 --> 216.66.80.30
        inet6 2001:470:1f0a:139e::2 --> 2001:470:1f0a:139e::1 prefixlen 128
        inet6 fe80::21f:c6ff:fe32:3f46%gif1 prefixlen 64 scopeid 0x7
