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 portion 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 network is 192.168.1.x, with the last digit “x” 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 determines 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 net- work 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. The maximum metric, or measure, of hops is 15.

Interface: Select LAN or WAN, depending on the location of the static route’s final destination.

DMZ Host

Figure 6-17

From the DMZ Host screen, shown in Figure 6-17, you can expose one local user to the Internet for a special-purpose service such as Internet gaming and videoconferencing.

Port Range Forwarding forwards a maximum of 10 ranges of ports, and DMZ Hosting forwards all the ports for one PC at the same time. DMZ Hosting is less secure.

•To expose one PC, enter the computer’s IP address. For more information about finding a computer’s IP address, refer to “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter.”

•Deactivate DMZ by entering 0 in the field. (This is the default setting.)
