What is the Proxy Server for PS4 and How Does It Work for Gaming?

I’ve been using a proxy server for PS4 for a few months now, and it’s been a mixed experience. Sometimes it works great, and other times it’s just meh. I think it really depends on the provider.

I’m currently using ProtonVPN, and it’s decent, but I’m open to trying others. If anyone has suggestions for a better proxy, let me know. Also, does anyone know if using a proxy affects your NAT type?
