I am trying to set up an ipv6 tunnel through Hurricane Electric. So far, I have no connectivity;

ifconfig:

he-ipv6   Link encap:IPv6-in-IPv4  
          inet6 addr: fe80::c0a8:164/128 Scope:Link
          inet6 addr: 2001:470:XXXX:YYYY::2/64 Scope:Global
          UP POINTOPOINT RUNNING 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)

ping:

martijn@desktop1:~$ ping6 ipv6.he.net -c6

Firewall on my local machine is open.

What could be the issue? Where am I going wrong?

You need to things in your firewall. 1) You need your IPv4 firewall to answer to PING. 2) You need to allow protocoll 41 to pass your firewall (that is not TCP/41 or UDP/41). – Anders Sep 2 '12 at 21:46
So you need to answer how this machine connects to IPv4 Internet. You also need to check that these changes are done on your router/NAT/firewall that connects your machine to Internet. – Anders Sep 2 '12 at 21:53
Output of iptables looks like this / 2 0 0.00 B ACCEPT 41 -- * * 0.0.0.0/0 0.0.0.0/0 - / – Anders Sep 2 '12 at 21:59
