ZyWALL 100 Internet Security Gateway
Remote Node Setup 9-5
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a
constant connection and the cost is of no concern.
The following table describes the fields not already described in Table 9-1.
Metric
The metric sets the priority for the ZyWALL’s 3 different possible default routes to the Internet. First there
is the normal route that your ISP designates. Second is the traffic-redirect route (see Traffic Redirect). The
third one is the dial-backup route (see Backup Remote Node Setup).
Menus 11.6 (Traffic Redirect) and 11.3 (Dial-backup) provide customizable metrics to determine the
priority of the 3 default routes. For example, if the normal route has a metric of "1" and the traffic-redirect
route has a metric of "2" and dial-backup route has a metric of "3", then the normal route acts as the
primary default route. If the normal route fails to connect to the Internet, the ZyWALL tries the traffic-
redirect route next. In the same manner, the ZyWALL uses the dial-backup route if the traffic-redirect route
also fails. If any two of the default routes have the same metric, the ZyWALL uses the following pre-
defined priorities:
1. Normal route
2. Traffic-redirect
route
3. Dial-backup route
For example, if you want the dial-backup route to take first priority over the traffic-redirect route or even
the normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or
greater).
