Testing a new firmware image before installing it FortiGate Firmware

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 FortiOS version (for example, reverting from

FortiOS v3.0 to FortiOS v2.80), you might not be able to restore the previous

configuration from the backup configuration file.

Testing a new firmware image before installing it

You can test a new firmware image by installing the firmware image from a system

reboot and saving it to system memory. After completing this procedure, the

FortiGate unit operates using the new firmware image with the current

configuration. This new firmware image is not permanently installed. The next time

the FortiGate unit restarts, it operates with the originally installed firmware image

using the current configuration. If the new firmware image operates successfully,

you can install it permanently using the procedure “Upgrading to a new firmware

version” on page 53.

Use this procedure to test a new firmware image before installing it. To use this

procedure, you must connect to the CLI using the FortiGate console port and a

null-modem cable. This procedure temporarily installs a new firmware image

using your current configuration.

For this procedure you:

• Access the CLI by connecting to the FortiGate console port using a

null-modem cable.

• Install a TFTP server that you can connect to from the FortiGate internal

interface. The TFTP server should be on the same subnet as the internal

interface.

To test the new firmware image

1 Connect to the CLI using a null-modem cable and FortiGate console port.

2 Make sure the TFTP server is running.

3 Copy the new firmware image file to the root directory of the TFTP server.

4 Make sure the internal interface is connected to the same integer as the TFTP

server.

You can use the following command to ping the computer running the TFTP

server. For example, if the TFTP server’s IP address is 192.168.1.168:

execute ping 192.168.1.168

5 Enter the following command to restart the FortiGate unit:

execute reboot
