Hi Omer,

I have been able to do it using:
apt-get install tspc

verify tun works:
ifconfig tun

and ping:
ipv6.google.com
PING ipv6.google.com(2001:4860:0:1001::68) 56 data bytes
64 bytes from 2001:4860:0:1001::68: icmp_seq=1 ttl=52 time=305 ms

64 bytes from 2001:4860:0:1001::68: icmp_seq=4 ttl=52 time=505 ms
^C

rtt min/avg/max/mdev = 305.720/435.197/505.567/91.669 ms


I also found 
http://www.cyberciti.biz/faq/tspc-debian-ubuntu-linux-configure-ipv6-tunnel/ 
as reference

But since it worked without a hitch didn't have to use it.

So I see two options:
1) Your firewall is blocking
2) Your NAT hinders it

Try to play with tunnel_mode=v6anyv4
and if_tunnel_v6v4=sit1, if_tunnel_v6udpv4=tun

They appear to (in several mailing list) allow you to circumvent the firewall 
issue.

You can use ethereal (wireshark) to see the data being sent on port 3653 - as 
well as the channel being built.
