Table 6-8 Traffic Redirect
LABEL DESCRIPTION
Active Select this check box to have the ZyWALL use traffic redirect if the normal WAN
connection goes down.
Backup
Gateway IP
Address Type the IP address of your backup gateway in dotted decimal notation. The ZyWALL
automatically forwards traffic to this IP address if the ZyWALL's Internet connection
terminates.
Metric This field sets this route's priority among the routes the ZyWALL uses.
The metric represents the "cost of transmission". A router determines the best route for
transmission by choosing a path with the lowest "cost". RIP routing uses hop count as
the measurement of cost, with a minimum of "1" for directly connected networks. The
number must be between "1" and "15"; a number greater than "15" means the link is
down. The smaller the number, the lower the "cost".
