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, 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 wanted 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 por- tion 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.

EtherFast® Cable/DSL Firewall Router with 4-Port Switch/VPN Endpoint

DMZ Host

Figure 7-42

From the DMZ Host tab, shown in Figure 7-42, you can set Port 4/DMZ to DMZ or LAN connection. Any user on the Internet can access incoming or out- going data from the DMZ host without the use of firewall protection. This fea- ture is used for special-purpose services such as Internet gaming and video- conferencing. Port 4 is the only port used for DMZ, and only one computer can be in DMZ mode.

DMZ Port

To enable or disable the DMZ port, click the Enable radio button or Disable radio button.

DMZ Host Address

Assigned by the DMZ Port: The DMZ host is the first PC connected to Port 4/DMZ of the Router, either directly or through a hub or switch. The Router will only allow one PC to be the DMZ host.
