Two VPN/proxy levels for the system. Wireguard/OpenVPN and then next one (Shadowsocks?) - experience?

Are you running your own VPS or using a paid VPN service?

I have setup my system with multiple proxies using v2ray. Using this, you have the ability to create several local https/socks5 listeners and route them to several types of upstream servers. It’s aimed at Chinese users, so it doesn’t natively support protocols like ovpn/wireguard which are easily detected and blocked in China, but can be configured.
