Forwarding

Figure 7-37

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.
