abled (unchecked), the backup routes system operates in the back-
ward compatibility mode based on the default priorities of the network

nection. When WAN communication via multiple interfaces is
received, the same interface is used in reply, therefor; the traf-

hind the router. The highest priority interface is used for these
transmissions.
