I cannot determine why my ipv6 tunnel is not working, Everything seems to register fine. I have few people help as well to debug it, but to no avail. I am using a linksys e2000 router and have tried enabling dmz. Anytime I try to ping6 out it just hangs with no response or failure. Any help explaining what I am doing wrong is appropriated

You're behind a NAT....you'd need to replace your public IP address with the private IP address...

I just noticed that after I posted, I am not sure if the linux route commands are working so I decided to try inserting it into my /etc/network/interfaces configuration. It doesn't seem to work though still cannot ping6 out.
