Hi Paul.

At that PI you should open and/or forward ports. Which OS are you running there?

At the main router it is needed only to open protocol 41 from he.net to your PI so that the tunnel works. Anything else on the IPV4 side is irrelevant.

In my Ubuntu:

tommi@pin:~$ sudo ufw status|grep ipv6
Anywhere                   ALLOW       216.66.84.46/ipv6

But all this seems to be working at your setup...
