I have a customer that has two buildings connected with Wi-Fi and one subnet 192.168.0.x. Building A has the WAN circuit and Building B has to go over the Wi-Fi to get internet. They want to put a new WAN circuit into Building B and add another FortiGate to go out to the internet but still maintain the Wi-Fi LAN. Can I do this without having to re-subtnet Building B? Can I deploy multiple Gateways without creating any problems?
