Well… That all depends.
If you trust this guy as much as I do:
then its pretty much plug and play for the price of an RPi, and 90 bucks a year.
Of course you don’t actually need the RPi, but that’s what makes it easy!
NOTE
The hardware option will inevitably force your entire machine (All Qubes) through the same VPN tunnel:
Qube/S > With or withoutTor > Hardware VPN > Outside world
Theoretically…
If that is not to your liking, and IF it is possible in Qubes for you to configure Ethernet Qubes (For the hardware VPN) AND a separate Wifi (Software VPN) Qubes network, then it could be possible to configure separate tunnels that are both running through your ISP router.
You could also run multiple RPi hardware VPN’s via Ethernet (If you don’t like getting microwaved to death) and/or multiple WiFi VPN’s
Also Note
This Hardware VPN method is NOT Qubes specific.
However - Multiple Networks on Qubes IS: ![]()
