Hello all, I have an existing network with some Cisco switches, this network has a fortigate firewall, my client want a separate network for WiFi, so he buys another router, we will work with as the main router for the WiFi lan. So we gonna use a fortigate firewall for the wifi network.

The problem is that we have one fiber link between the access switches that exist in the building and the exciting firewall. And we want to use them to link the new omada switchs to the new firewall.

I want help, coz I didn't figure out how to configure the new network on the existing one using two firewalls.
