Cable/DSL Firewall Router with 4-Port Switch/VPN Endpoint
65
From the Forwarding tab, shown in Figure 7-37, 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
Forwarding, the Router’s DHCP function must be disabled under the DHCP tab
and the computer must be assigned a new static LAN IP address because the IP
address may change when using the DHCP server.
