WER-401 Wireless SOHO Firewall Gateway
FIELD DESCRIPTION
Address network number.
Subnet Mask
Enter the subnet mask for this destination. If you need to specify a route to a single
host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the
network number to be identical to the host ID.
Default Gateway Enter the IP address of the gateway to the destination network. The gateway is the
next router that your router contacts in order to forward packets to the destination.
On the LAN, the gateway must be a router on the same segment as the router. Over
the WAN, the gateway will be the IP address of the router at your ISP.
Hop Count (Metric,
max 15) This is the “cost” of transmission for routing purposes. IP routing uses hop count as
the measurement of cost with a minimum of
1 for directly connected networks. Enter
a number that approximates the cost for this link. The number need not be precise,
but it must be between
1 and 15 . In practice, 2 or 3 is usually a good number.

6.3.1 Static Route Example
As an example of when a static route is needed, consider the following case:
•
Your primary Internet access is through a cable modem to an ISP.
•
You have a router on your home network for connecting to the company where you are employed.
This router’s address on your LAN is 192.168.1.100.
•
Your company’s network is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route was created
with your ISP as the gateway, and a second static route was created to your local network for all 192.168.x.x
addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router
will forward your request to the ISP. The ISP forwards your request to the company where you are employed,
and the request will likely be denied by the company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through
your home router at 192.168.1.100. In this example:
