Your router is probably blocking protocol 41.  Capture some traffic and see what you can see

Is your router behind nat?
What commands did you specifically run to bring up the tunnel on your linux box?

There is your issue:

Code: [Select]
ip tunnel add he-ipv6 mode sit remote 192.168.0.XX local 46.194.146.152 ttl 255
remote needs to be the tunnel-server's IP, and local needs to be that 192.168 ip. Also obfuscating your internal IP and not your external, is like, the most backwards way of trying to protect your IPv4 address, which doesn't need obfuscation when you ask for troubleshooting help anyways ;)

now it did

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.66.80.90 local 192.168.0.63 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:27:2ec::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr


it is also

Then it is one of three things:

1) your IPv4 endpoint is not up to date in the broker. If it looks like it is, try changing it to something else that pings, and then change it back.
2) your tunnel isn't built correctly on HE's side. email ipv6@he.net and have them verify it is, after you've tried #1.
3) your NAT appliance doesn't pass Protocol 41 IPv6 tunnels to your machines behind it. Most likely need to replace that NAT appliance if this is the case.
