Best practices for VPS hardening when running a Snowflake proxy?

Hi everyone,

I’ve recently set up a standalone Snowflake proxy on a Debian-based VPS to help out with the censorship circumvention efforts. I’m seeing some consistent traffic, which is great, but I’m curious about the community’s thoughts on resource isolation.

Are there specific sysctl tweaks or firewall configurations you recommend to ensure the proxy doesn’t negatively impact the stability of other lightweight services on the same instance? I want to make sure I’m contributing to the network without compromising my own server’s performance.

Thanks for any insights!
