I'm not a networking guy, by any stretch, but I will occasionally remote into the office Cisco ASA 5505 firewall and do some simple configuration.  With the Cisco, if you want to open a port and then configuring port forwarding, it's a two-step process.  

1. Open the port in the firewall.
2. Configure port forwarding for the port.

I was configuring a D-Link yesterday and it appeared that the port filtering and port forwarding was combined into one interface  Does that seem right?

Do I configure port filtering and port forwarding with the same interface on simpler home-office routers?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
