Forwarding
The Port Range Forwarding screen allows you to set up
public services on your network, such as web servers,
FTP servers, email servers, or other specialized Internet
applications. (Specialized Internet applications are any
applications that use Internet access to perform functions
such as videoconferencing or online gaming. Some Internet
applications may not require any forwarding.)
When users send these types of requests to your network
via the Internet, the Router will forward those requests to
the appropriate computers (also called servers). Before using
forwarding, you should assign static IP addresses to the
designated computers (use the DHCP Reservation option on
the Basic Setup screen; refer to DHCP Reservation, page 16).
If you need to forward all ports to one computer, click the
DMZ tab.

mapping rules.
