The DMZ Hosting feature, shown in Figure 9-22, allows one local user to be
exposed to the Internet for use of a special-purpose service such as Internet
gaming and videoconferencing.
Whereas Port Range Forwarding can only forward a maximum of 10 ranges of
ports, DMZ hosting forwards all the ports for one PC at the same time.
• To expose one PC, enter the computer’s IP address. To get the IP address of a
computer, refer to “Appendix F: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
• Deactivate DMZ by entering a 0 in the field.
When finished, click the Apply button to save the settings. Otherwise, click the
Cancel button to undo changes made on this screen.

2. Enter the following data to create a new static route.
Destination LAN IP: The Destination LAN IP is the address of the
remote network or host to which you want to assign a static route. Enter the
IP address of the host for which you wish to create a static route here. If
you are building a route to an entire network, be sure that the network por-
tion of the IP address is set to 0. For example, the Router’s standard IP
address is 192.168.1.1. Based on this address, the address of the routed net-
work is 192.168.1, with the last digit determining the Router’s place on the
network. Therefore you would enter the IP address 192.168.1.0 if you want-
ed to route to the Router’s entire network, rather than just to the Router.
Subnet Mask: The Subnet Mask (also known as the Network Mask) deter-
mines which portion of an IP address is the network portion, and which
portion is the host portion. Take, for example, a network in which the
Subnet Mask is 255.255.255.0. This determines (by using the values 255)
that the first three numbers of a network IP address identify this particular
network, while the last digit (from 1 to 254) identifies the specific host.
Default Gateway: This IP address should be the IP address of the gateway
device that allows for contact between the Router and the remote network
or host.
Hop Count: This determines the maximum number of steps between net-
work nodes that data packets will travel. A node is any device on the net-
work, such as PCs, print servers, routers, etc.
interface: Select LAN or WAN , depending on the location of the static
route’s final destination.
