From the Forwarding tab, shown in Figure 6-31, you can set up public services
on your network, such as web servers, ftp servers, or e-mail servers. 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 Forwarding, you
must disable the Router's DHCP function from the DHCP tab and assign the
Router a new static LAN IP address, as the IP address may change when using
the DHCP server.
If you need to forward all ports for one PC, see the section on DMZ hosting.
To add a server using Forwarding:
1. Enter the port number or range of ports used by the server. On the same
line, select the protocol UDP, TCP, or Both, and enter the LAN IP address
of the server that you want the Internet user to access.
2. Configure as many entries as needed—the Router supports up to ten ranges
of ports. Click the Apply button and Continue button when finished.
