Reverse path check fail

Hello,

 

I am having a routing problem on my FOrtigate.

I have created 2 DMZ zones on a single FortiGate interface.

When communicating from a different subnet from a DMZ interface, I encounter the following error message: Reverse Path Check.

 

08/07/2020: Problem solved I solved the problem, adding a static route for the specified subnet.

"Reverse path check fail" simply means that the FGT did not find any matching route back to the destination address for handing the reply to your request back to you.

You solved exactly that by adding the static route :)
