VPN Tunneling with Android using Wireguard + FreeBSD

Hello, this is Muno. I was curious, so I had already set up a VPN tunnel between my VPS and home server, but I hadn't connected my smartphone yet, so I decided to do it.

Via my home network environment, WiFi 11ac

After that, connected to the VPN server built on Vultr.
Honestly, I rarely do anything through a VPN for my usual purposes, but it's good to have it if I need it (though the upload results seem strange, so I might have made a mistake).
In this case, I had to configure pf's NAT routing, but I managed to get it working.

It seems that Wireguard private key generation cannot be done from the app side, so it's necessary to use wg genkey or wg pubkey on a PC with Wireguard installed.

If you're looking for a 'hacky' way to use it, some people connect to a Turkish VPN to pay for YouTube Premium in Turkish Lira because it's cheap, but I don't feel like going that far.
That's all for now. Thank you.
