Tunnel:T71605
Subnet: R45434
My tunnel is up and works fine. I can ping from the router all IPv6 hosts.

PING ipv6.google.com(fra07s07-in-x67.1e100.net) 56 data bytes

On the router is installed and configured radvd program, is also activated forrward, still on the computers on your local network ipv6 does not work.
I can ping the gateway (router) and PoP IPv6 from local network.

Ping is great, but what is the source address, what is the route, where are the other details that are requested by that big yellow/orange box?

Again
My tunnel is up and works fine. I can ping from the router all IPv6 hosts.
On the router is installed and configured radvd program, is also activated forrward, still on the computers on your local network ipv6 does not work.
I can ping the gateway (router) and PoP IPv6 from local network.
Network does not work behind the POP form subnet addres.
