The router suppor ts objects for determining the state of backup, as well as providing traps for the backup and
recover y events. No objects suppor t configuration of backup or recover y.
Backup Default Gateway
Introduced in version 5.1.2, the firmware offers backup functionality to an alternate gateway typically connected
to a LAN por t.
A typical application would be to have a LAN connection from your 4000-Series router to another router that
has, for example, an ISDN or analog modem connection to the Internet, and designating the second router as
the backup gateway. Should the primar y WAN connection fail, traffic would be automatically redirected through
your alternate gateway device to maintain Internet connectivity.
Two menus control the backup gateway feature:
■ the Backup Configuration screen in the WAN Configuration menu
Here, you enable the backup feature and set some parameters.
■ the IP Setup screen in the System Configuration menu
Here, you set the IP address of the alternate gateway device.
