And what I like about Wireguard is that you can't port scan for it. The protocol is designed in such a way that the wireguard server won't respond unless you know the right key.

Not saying wireguard isn't.

I will say I've used softether on 10gbps links and hit 8gbps between two continents and that was nearly impossible with every other solution 5 years ago when I first set it up. It's been running flawlessly since then.
