Example:
In this scenario shown in figure 10.1, two ISP:s (ISP A and ISP B) are used
to connect to the Internet. ISP A is connected to the WAN1 interface of
the firewall and ISP B is connected to interface WAN2. In order to
configure the D-Link firewall to use ISP A as primary ISP, and ISP B as
backup ISP, monitored routes will have to be configured.
We will need two routes, one default route (0.0.0.0/0) with metric 1, that
use the default gateway of ISP A and one default route with metric 2 that
use the default gateway of ISP B.
