Belkin F5D8233 router and using Remote Desktop

I previously used ZoneAlarm for my firewall but recently purchased a Belkin F5D8233 router. I used Remote Desktop to access my pc from my job. Now that I have the router I am unable to use RDP.

Belkin has tried giving suggestions. I’ve setup port forwarding. I’ve setup the dynamicDNS service but doesn’t appear to work properly.

Does anyone have this router and uses RDP to access their machine from outside the network and if so what did you do to resolve it?
