Backup Default Gateway
If your Netopia equipment does not have an internal modem, or if you do not want to use the internal modem for
backup, the Netopia Firmware Version 8.7 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 ENT Enterprise-Series Router to another
gateway that has, for example, an ISDN or analog modem connection to the Internet, and designating the
second gateway 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.
