Here's the situation:
Windows 7 Ultimate ---> Router ---> Internet
The router has been configured as the end point for the tunnel and it seems to work as it should, i.e. I can ping6 any IPv6 enabled site, such as ipv6.he.net or ipv6.google.com. However, when I attempt to do the same from my PC, it fails with 'request timed out'.
What I've done so far is to use the router to allocate an address for the PC, I've also tried setting a static address on the PC NIC (I may well be choosing an incorrect address) I also use the set-up instructions for the tunnel from the HE site, however, I changed the endpoint to the IPv4 address of my PC.
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.1.143 216.66.80.30
netsh interface ipv6 add address IP6Tunnel 2001:470:1f0a:823::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f0a:823::1
In the interface of the router, there are options for setting different IPv6 addresses (see attached) I used the Client IPv6 address, supplied by HE, for the WAN side of my tunnel, but wasn't sure what to use for the LAN address. I did try 2001:470:1f0a:823::3, I also used this as well as ::4 when I set a static address on the NIC. I have also tried setting different gateway addresses ::1, ::2 and ::3.

The DNS addresses were obtained from my firewall logs...
Obviously, I'm doing something wrong but I don't know what. any help would be appreciated.
Incidentally, when IPv6 is enabled on the NIC any site that is both IPv6 and IPv4 enabled, such as HE, takes a long time to load and sometimes simply times-out altogether. Disable IPv6 on the NIC so only IPv4 is used and there's no problem. Is that a DNS issue or simply the tunnel not working?
One final point, I have rules in my firewall to allow protocol 41, IPv6 DNS as well as ICMPv6. I also tried without the firewall installed.
