WARNING! In order for this kind of “failover” to work, LAN bypass must be disabled
and Link state failover must be enabled. They are both disabled by default.
LAN Bypass and Link State Failover Settings
In the Preconfiguration console, LAN bypass must be disabled and Link state
failover must be enabled in order for a load-balancing “failover” deployment to
work.
LAN Bypass
LAN bypass is a feature by which, if the appliance encounters an error that causes
scanning to stop, network traffic will still flow through the appliance unscanned, so
that network traffic is not interrupted (disabled by default).
Link State Failover
Link state failover is a feature by which, if either the INT or the EXT port stops func-
tioning, both ports are automatically shut down (disabled by default).
Setting LAN Bypass and Link State Failover Options
If you have previously enabled LAN bypass, you can disable it through the InterScan
Gateway Security Appliance Preconfiguration console. Likewise, you can enable link
state failover on the same screen of the Preconfiguration console. See
Enabling or
Disabling LAN Bypass and Link State Failover on page 5-6 for details.
