I'd be more interested if wireguard is an option, and how it performs. Since they're already on linux/oss.

IPSec is pretty much the standard interop still - pretty much everything talks it Cisco, Juniper, pfSense, Fortinet, etc. You name it I’d be surprised if it didn’t have support.

I’d love to see wireguard implemented in the networking world, but I think it may take some time to get there :/
