Custom Default Image
As the default image is burned early in the lifecycle of the appliance, it sometimes becomes
obsolete and lacks important security fixes or other updates. Therefore, you may want to
replace it with a newer image.
If you select to install a custom default image, you can also preserve settings, policy, SIC, or
the license as part of the default image.
To update the default image:
Run this Gaia Clish command:
update default-image from current-image preserve-settings yes
force yes
If you configure the value of "preserve-settings" to "no", you can only preserve the SIC
and license.
If you configure the value of "force" to "no", the appliance asks you to confirm before it
reboots.

Fonic Bypass
Note - This topic is only applicable for the 1595R Wired model.
The 1595R wired model has a FONIC (Fail Open Network Interface Card) bypass mechanism
implemented between the DMZ and LAN4 ports.
The Bypass mechanism is automatically activated when one of these occurs:
n
Power to the appliance is down.
n
There is a critical software failure (using watchdog logic).
These are the two Bypass mechanism modes:
n
Active - The connection between DMZ and LAN4 ports work as a normal system
interface and drive data through the appliance, as long as the power is on and the
software is valid. If the appliance power is off or the software has a critical problem that
prevents it from maintaining a keep-alive mechanism, the Bypass circumvents the DMZ
and LAN4 port connection and traffic bypasses the appliance.
n
Force-bypass - "Bypass". The connection between the DMZ and LAN4 port is forcibly
bypassed and the traffic bypasses the appliance regardless of the software status.
