I want to use Privoxy hosted on my VPS as an HTTP proxy for when I will be travelling to China. However, I don't want just anyone to be able to use it.
I google'd around, and it doesn't look like HTTP proxies typically allow setting username/password protection, and there isn't any field to input this information in Firefox's settings anyway.
But, I think you can filter the people allowed to connect by IP. I will be travelling a lot, thus my IP will change a lot, so is there a way to filter the allowed connections by a dynamic DNS service. I could just update the IP through the DNS service, and then connect to the proxy.
