Unable to add my active ISP WAN interface as SD_WAN Member to a SD_ZONE , the interface does not show up when adding it to a SD-WAN zone. This is for my home lab, I am  running forti os 6.4.5. my  ISP WAN 2 is down. cable is connected, because i only have 1 ISP connection, but i still assigned IP to it.

Hello JOSIAH_BOZIAH,

Your internet connection will be interrupted as you will have to remove all the references associated with WAN1 in order to add it as an SDWAN member.
