Route is used when joining two or more different networks together via the 450U-E. Refer to Section 1.1 for more details.
When routing from one subnet to another devices on one subnet need to know where to pass the message to get it to
the other subnet. This is done one of two ways;
Setting up a route within the device which is a lookup table showing a list of subnets and which IP address to use
as the Gateway.
Setting up a default Gateway address on the modem. This is a link to an IP address that knows how to get to the
required where if it does not know where to send the message it will
sent it to the default Gateway.
If there are multiple networks each with a different IP range, routing rules must be used as the Default Gateway only
allows one address to be configured.
In the example below a routing rule needs to be entered into which will allow access from Network A to
Network B.
To enter a Routing rule:
Open a DOS command window and enter the following command at the prompt.
Route ADD 192.168.2.0 MASK 255.255.255.0 192.168.0.191
This routing rule states that if you wish to access any IP address on network B (192.168.2.0) with the Netmask of
255.255.255.0 the message needs to be sent to 192.168.0.191.
Devices on Network B should also have their Default Gateway Address set to the Routers Wireless address
(192.168.2.191). This will ensure that any traffic destined for the 192.168.0.0 network can be returned successfully.
There are a number of Route commands that can be used to edit, manipulate, and delete routing rules. They are briefly
explained below.
Route PRINT: will show all active routes on PC,
Route ADD: will add a routing table to network, format: Route<IP Address> Mask<Subnet Mask> <Route IP Address>
Route DELETE: will delete the unwanted routing table, format: Delete <Destination IP >
Route CHANGE modifies an existing route, format: Change<IP Address> Mask<Subnet Mask> <Route IP Address>
