Installing firmware images from a system reboot using the CLI FortiGate Firmware
11 Enter the firmware image filename and press Enter.
The TFTP server uploads the firmware image file to the FortiGate unit and
messages similar to the following are displayed:
• FortiGate unit running v2.x BIOS
Do You Want To Save The Image? [Y/n]
Type Y.
• FortiGate unit running v3.x BIOS
Save as Default firmware/Run image without saving:[D/R]
or
Save as Default firmware/Backup firmware/Run image without
saving:[D/B/R]
12 Type D.
The FortiGate unit installs the new firmware image and restarts. The installation
might take a few minutes to complete.
Restoring the previous configuration
Change the internal interface address, if required. You can do this from the CLI
using the following command:
config system interface
edit internal
set ip <address_ipv4mask>
set allowaccess {ping https ssh telnet http}
end
After changing the interface address, you can access the FortiGate unit from the
web-based manager and restore the configuration.
For more information, see the FortiGate Administration Guide.
If you are reverting to a previous firmware version (for example, reverting from
FortiOS v3.0 to FortiOS v2.80), you might not be able to restore your previous
configuration from the backup up configuration file.
