Identity management for WireGuard

Hey there, Netmaker author here. Thanks for the article, this is a really great comparison that lays out a lot of pros/cons of the available options.

I just wanted to point out a couple of small things worth correcting from the Netmaker section (can't speak for the other platforms):

1. We do have a client GUI - It's not enabled on Linux by default since most users prefer CLI, but there is one available, and is installed by default on Mac/Windows.

2. We do NAT traversal via our own UDP Hole Punching method (it is very lightly mentioned here https://docs.netmaker.org/architecture.html#netmaker-server, though we should definitely expand on it).

There's definitely a lot more we can be doing, and we're working on getting those things done. Hopefully you can do an update article in 6 months or so and see where we've gone from here!
