Problem in setting up the tunnel
« on: January 24, 2010, 11:14:31 PM »

Hi, I have setup my tunnel but I seem to have problems with it, I cant pass any traffic over it.

ip -6 route
fe80::/64 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 4294967295
default dev he-ipv6  metric 1  mtu 1480 advmss 1420 hoplimit 4294967295

tunnel
he-ipv6   Link encap:IPv6-in-IPv4
          inet6 addr: 2001:470:mpla:mpla::2/64 Scope:Global
          inet6 addr: fe80::4f6b:4005/128 Scope:Link
          UP POINTOPOINT RUNNING NOARP  MTU:1480  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:577 dropped:0 overruns:0 carrier:577
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

I cant even ping the other end of the tunnel
ping6 2001:470:mpla:mpla::1
PING 2001:470:mpla:mpla::1(2001:470:mpla:mpla::1) 56 data bytes
From 2001:470:mpla:mpla::2 icmp_seq=1 Destination unreachable: Address unreachable

any help would be appreciated

This isn't really enough information.  ifconfig -a and netstat -rn would help.  as would ip -6 addr and ip addr and ip tun.

The most common problem is people using their public IP on an IPv6 router behind a NAT.  If you're behind a NAT router, use the actual address of your router instead and let your NAT device NAT it.

where did you get that fdf1 address?

Your stf0 interface has a teredo address

Are you trying to use an HE tunnel?  I would disable teredo and fix your fdf1 address on lo0

Looks like you're still running 6to4.  You need to set up the HE tunnel on your GIF interfaces.  Should work like *BSD since it's MacOS.

Oops, I meant 6to4, not teredo.

Thanks for the catch jimb
