Fortigate return to NAT mode from transparent mode

[DanieleS99]

Hi,

If I wanted to return to NAT mode after configure the Fortigate in transparent mode with firewall policies, security policies, etc.. What are the steps?

Obviously remove the commands of transparent mode and assign ip addresses on interfaces. Other things?

Thanks

Hi,

Use the following procedure to switch the FortiGate unit from Transparent mode to

NAT/Route mode. When the FortiGate unit has changed to NAT/Route mode its

configuration resets to NAT/Route mode factory defaults.

1) Go to System > Status.

2)Select Change to NAT Mode.

3)Select NAT/Route in the operation mode list.

4)Select OK.

The FortiGate unit changes operation mode.

5)To reconnect to the web-based manager you must connect to the interface configured

Access through default for management access.

May it be possible set the Fortigate 110C to Route Mode by CLI?

@DanielleS99: the keyword in Habeeb's post is "factory reset"!

BEWARE!

That is, you will lose your current config. IF FortiOS doesn't ask you for a management IP when enabling Route mode, then it will default to 192.168.1.99/24 on port "mgmt" or "port1", depending on model.

Tip: Log in via the console port to do this. You will retain connectivity, can look up the correct management port ("get sys int") and you could change the IP immediately if convenient.
