Port forward from LAN-1 using WAN-1 internet to LAN-2 using WAN-2 internet on the same for

[Allwyn_Mascarenhas]

As seen in the diagram is such a network setup possible? The port forwarding works just fine when I try it from an internet connection from somewhere outside my office but says timeout when trying it from the 6.0 network.

I am also using policy route to force the 6.0 traffic through wan1. I tried various ways to access the 5.0 network through internal routing itself but that did not work out too. Not sure what i am missing. appreciate all help, thanks.

got response from fortinet TAC:

I dont think this is possible, fortigate has the port forwarding ip address fortigate wont sent the packet out to wan1. You may raise up a ticket to have alternative/workaround for this.
