Internet failover 
SnapGear appliances are designed with the real Internet in mind, which may mean 
downtime due to ISP equipment or telecommunications network failure. Failures can be 
caused by removing the wrong plug from the wall, typing in the wrong ISP password or 
many other reasons. Regardless of the cause of a failure it can potentially be very 
expensive. 
Failover provides the ability to use a low-speed connection when the high-speed 
connection fails to allow services to continue operating. When the main Internet 
connection fails and the backup connection (or failover) is started, VPN connections are 
restarted and dynamic DNS services are advised of the new IP address. 
Internet failover is currently only available in the SnapGearSOHO+, SnapGearPRO, and 
SnapGearPRO+ appliances. After configuring a normal Internet connection, a link to the 
Internet failover page allows you to configure failover support. You can also access the 
failover page by clicking Connect To Internet in the Networking menu. 
The following figure shows the advanced configuration options:
