Administrator’s Handbook

Once Backup is configured, a new field appears in the Home Page.

If your DSL WAN link fails, you can switch to your Backup Gateway by clicking the Force Backup button.

Automatic options

If you select automatic as your Backup option, the screen expands to allow you to enter additional informa- tion.

•Failure Timeout (minutes 1-10) – Enter the number of minutes you want the system to wait before the backup port becomes enabled in the event of primary line failure. This allows you to be sure the WAN connection is not merely briefly interrupted before the gateway switches to backup mode.

•Ping Host 1 and Ping Host 2 – Select address or name from the pull-down menu enter IP address(es) or resolvable DNS name(s) that the Gateway will ping.

The Gateway will ping both addresses simulta- neously at five-second intervals, recording the ping responses from each host. The Gateway will proceed into backup mode only if neither of the configured remote hosts responds.

☛Note:

For best results, enter an IP address and not a host name. If a host name is used it may not be resolvable, and may keep the interface down.

•While the Gateway is in backup mode, it will continue to ping both hosts via the primary interface. If either host responds to a ping and the Auto Recovery checkbox is checked, the Gateway will revert to the primary interface.

•If you chose Auto Recovery, select Recovery Timeout (minutes1-10). Enter the number of minutes you want the system to wait before attempting to switch back to the WAN connection. This allows you to be sure that the WAN connection is well re-established before the gateway switches back to it from the backup mode.

•Check the Enable Backup Gateway checkbox
