yes for a long time now

I remember maybe 12-15 years ago, setting OpenVPN on my TomatoUSB flashed router, invoking all kind of openssl command to generate certificates, keys, signing stuff, setting the router, setting the TAP/TUN clients etc. but once setup it works for years on my laptop, phone, etc.

Now with WG I basically scan on my phone a QR code generated on my Merlin router and that’s it.

I have a 240W extension from AliExpress, used with a 120W power for my laptop, it never gets hot even when using 100+W
