– Routing
The static routing function determines the path that data follows over your network before and after
it passes through the GWR Router. You can use static routing to allow different IP domain users to access
the Internet through the GWR Router. Static routing is a powerful feature that should be used by advanced
users only. In many cases, it is better to use dynamic routing because it enables the GWR Router to
automatically adjust to physical changes in the network’s layout.
The GWR Router is a fully functional router with static routing capability.

Description
Routing Table
Dest Network
This parameter specifies the IP network address of the final destination.
Routing is always based on network number. 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.
Netmask
This parameter specifies the IP netmask address of the final destination.
Gateway
This is the IP address of the gateway. The gateway is a router or switch (next
hope) on the same network segment as the device’s LAN or WAN port. The
gateway helps forward packets to their final destinations.
For every routing rule enter the IP address of the gateway. Please notice that
ppp0
interface has only one default gateway (provided by Mobile operator) and
because of that there is no option for gateway when you choose
ppp0
interface.
Metric
Metric represents 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.
