Ubuntu 10.10 desktop, tunnel not working

[mnickerson]

Settings:

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
        endpoint 72.52.104.74
        address 2001:470:1f04:173a::2

        local 10.50.0.84
        gateway 2001:470:1f04:173a::1
        ttl 255

** I've also changed local to my global IP address 67.xxx.xxx.xxx, but that didn't change the result.

I've also used this:
ifconfig sit0 up
ifconfig sit0 inet6 tunnel ::72.52.104.74
ifconfig sit1 up
ifconfig sit1 inet6 add 2001:470:1f04:173a::2/64
route -A inet6 add ::/0 dev sit1

This config did not bring up the tunnel successfully either. I've tried a couple other configs and the results are the same, each time I got to the ipv6 verification link it just says i am connecting with my ipv4 address.

you did use your nat'd address to try and create the tunnel?  does your router/firewall pass protocol 41?

[mnickerson]

Looks like the problem was the firewall. Setting up on an external IP brought up the tunnel.

I am having the same exact issue and would LOVE to know how you fixed it....   what do you mean by "Setting up on an external IP brought up the tunnel."?

Did you have to mess with the iptables or bind?  I've been at this for a week now and can't get it to work.  If i install gogoc the "tun" interface that it creates works fine for me but i cannot get the TB tunnel to work at all.

Any help is appreciated.

I think he means that instead of it being firewall ==> tunnel server, he made it tunnel server ==> firewall
