Hello techies,

We have requirements to configure the firewall without changing the IP addresses on the existing infra.

We have a plan to configure the Firewall in Transparent Mode.

The attached Scenario is possible? and any one implemented the below scenario?

Hello @Suh_Ahamed ,
Yes it is possible. Usually in transparent mode the firewall does not change the packets, but only inspecting the flow.
Here is a useful handbook to help you in your configuration .

Hello techies,

The below solution will create a layer 2 loop ?

or it's possible in the FortiGate firewall with TP mode.
