Windows 10 Always On VPN...and licensing?

A request regarding using Windows 10 Always On VPN to connect via the F5 VPN has come up. One configuration I've seen is fairly basic, with a couple of vservers and pools for UDP ports 500 and 4500 for load balancing RRAS servers. I'm assuming this would require no licensing, unlike a VPN config using APM. Is that the case? As I'm just now looking at this, some of my information may be incorrect.
