I've seen VPN used on mesh wifi systems so that's not an issue. But that was the usual CLIENT. Maybe you are asking for a VPN SERVER but no one I know puts that over WiFi. You can try but I'm going with no to that. For a VPN server you want reliable so it's wired, not WiFi.
Im looking for suggestions on what brand and model of mesh wifi system to purchase that allows for a dedicated ip to be used, as a vpn?
