Port Range Forwarding

Figure 6-20
From the Forwarding tab, shown in Figure 6-20, you can set up public services
on your network, such as web servers, ftp servers, e-mail servers, or other spe-
cialized Internet applications. (Specialized Internet applications are any appli-
cations that use Internet access to perform functions such as videoconferencing
or online gaming. Some Internet applications may not require any forwarding.)
When users send this type of request to your network via the Internet, the
Router will forward those requests to the appropriate PC. Before using Port
Range Forwarding, the Router's DHCP function must be disabled under the
DHCP tab and the Router must be assigned a new static LAN IP address
because the IP address may change when using the DHCP server.
If you need to forward all ports to one PC, see the "DMZ" section.
To add a server using Port Range Forwarding:
1. Enter the name of the application in the appropriate Customized
Applications field.
