Good news, you need less than $250. Just buy a Protectli appliance, install OPNSense on it with the wireguard plugin. Setup Mullvad config and route all traffic through the tunnel. That's it!

I've been running a similar setup for a couple years now. It's been great.

Or spend less than $80 on GL.iNet GL-MT1300 travel router

or $90 on GL.iNet GL-AX1800 Wifi-6 router with MullVad support preconfigured.

Nothing to install, tweak or have hassles with.

Or around 50$ for a cheap mikrotik box, though it will struggle with full gigabit routing.
