Can I use a vpn with the buzz boxs I have 2 boxs .my IPTV sub. now requires me to get a vpn if allowed which is best for this box

Yes. I don’t have but You can try bunch since most if not all offer cancellation and money back. You can also test free like proton.

I use Windscribe Pro personally and I install ProtonVPN (free Tier) for many of my friends) on a variety of buzz boxes.

But you can use pretty much most VPN services.  Most work pretty much the same.

The only box which is a little different is the L1 (which is Linux and not Android), which only has OpenVPN client installed so whatever service you decide to get, you need to generate ovpn credentials to use it.   

BTW: Don't pay full price for any VPN service, many of the cashback sites like topcashback and rakuten often have offers for 100% cashback offers on a number of VPN services (sometimes more).  Google is your friend.
