I am trying to Setup a Regular IPv6 Tunnel on the website http://tunnelbroker.net/ipv6_normal.php but i am receiving the error:

Error: Your IPv4 endpoint is unreachable or unstable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall.
Error: Your IPv4 endpoint is unreachable or unstable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 216.66.84.46 through your firewall.

I am using Windows 7 x64 with a Netgear WNDR 3700 router.

In the router i have enabled ping response.
Set NAT to open.
Enabled a DMZ to my (static)computers ip address.
And have added static routers for the  66.220.2.74  and  216.66.84.46 ip addresses.

On my pc i disabled the firewall and virus protection.

My ip address is pingable, so ICMP is working.

Can anyone help me resolve the problem that i am not able to setup the tunnel?
