Before going to a long 3 month trip to Asia last year, I installed WireGuard on my Raspberry Pi 1 (original model B from 2012) which was running at home in US. I found PiVPN to be the easiest way to install Wireguard. I didn't know if I even needed a VPN but I was glad, and I was able to use internet as if I were at home. It was weird, but a lot of sites are blocked oversea, even though it shouldn't. For example, I couldn't access Homedepot.com. I also couldn't make payment to my Target card as the website refused connection. Apparently a lot of US business sites refuse to connect from oversea IP because of too many hacking attempts, or they just don't want to deal with it. Anyway, I was glad I had set up a VPN before I left for the trip.
Also, the original Pi (2012) was able to run Wireguard well enough for light VPN, although I didn't push it too much since I didn't use it for anything heavy like video streaming.
