Enable the primary connection for failover
Set up your primary broadband Internet connection as described in the Internet section of
this chapter. From the Connections menu, select Edit failover parameters from the
Configuration pull down box.
The CyberGuard SG appliance determines whether an Internet connection is up by
listening for responses to ping (ICMP echo request) packets sent to a host on the
Internet. Ensure you choose a host on the Internet that can be contacted reliably and
responds to pings. You can check whether you can ping a host under Diagnostics
->
Network Tests -> Ping Test.
Figure 3-6
Enter the IP address of this host in IP Address to ping.
Ping Interval is the number of seconds to wait between sending pings.
Number of times to attempt this connection is the number of failed attempts before
this connection is considered failed.
Time to wait between re-trying connections is the number of seconds to wait between
connection attempts.
Set up a secondary backup Internet connection
To switch to a dialout Internet connection when you primary broadband Internet
connection is unavailable, from the Connections menu select the appropriate Failover
Internet configuration for the COM/Modem port if setting up a narrowband dialout
failover Internet connection, or the DMZ port if setting up a broadband failover Internet
connection.
