Are your ip's reverse mapped in your DNS? Some sites won't display unless
they can reverse map your ip. Your router should be reverse mapped by your
ISP, so it would work. The best way to try and see if you are properly
reverse mapped, is to run nslookup and set the server to your isp's DNS.
Type in one of you ip's and see if it will resolve.
Hope this helps
