Webserver not working with new router

I've just updated my router to the Netgear DGN3500. My websites on my server no longer work although the internet does work on the server. On the router I've setup the port forwarding so the incoming services are pointing to the server's LAN IP address. I've tried to reset the router and disabled the server's firewall and Windows firewall and able to ping the website's domain name. When switching to my old router the websites work again. I have 1 static IP address and using Windows Server 2008.

Any help is appreciated
