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. In the example above, the Network 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) would identify the specific host.
Default Gateway IP 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 value gives the number of nodes that a data packet passes
through before reaching its destination. A node is any device
on the network, such as switches, PCs, etc.
Interface This interface tells you whether your network is on the internal
LAN or the WAN, or the external Internet. If you are connecting to a sub-
network, select LAN. If you’re connecting to another network through the
Internet, select WAN.

If your Router is connected to more than one network, it may be necessary to
set up a static route between them. A static route is a pre-determined pathway
that network information must travel to reach a specific host or network. Click
the Show Routing Table button to view the current static routing configura-
tion.
To create a static route entry:
1. Select Static Route Entry from the drop down list. The Cable/DSL Router
supports up to 20 static route entries.
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 zero (0). For example, the Router’s standard IP
address is 192.168.1.1. Based on this address, the address of the network to
which the Router is connected is 192.168.1, with the last digit (1, in this
case) determining the Router’s place on the network. Therefore you would
enter the IP address 192.168.1.0 if you want to route to the Router’s entire
network, rather than just to the Router.
