They have also Tailscale plug-in. You have to trust the company out of China or HK, though.
I agree with this recommendation - they work great with Wireguard. And if you're travelling, some of the features like handling captive portals are handy.
They are good wireguard clients but not servers
What's the difference?
On GL.iNet website they state: "OpenVPN and WireGuard speeds will be slower when running the device as a server. Results above are in client mode."
