My comments are turning into an answer, so here's some thoughts: DLink is a terrible idea, I can't say enough bad things about their equipment.

This is a block of 4 IPs, 1 of which is usable by the customer (The first IP is the network IP, the last IP is the broadcast, and one of the 2 in the middle would be the router, ...

This feature is distinct from the idea of forwarding incoming requests from a listening port on the router's public IP to a device "behind" the NAT / firewall (which is handled in the ...
