How to protect Nginx based proxy from unauthorized access?

Question

Nginx

I had an idea to take a VPS, install Nginx on it, and configure it as a proxy in order to access the Internet through it. More precisely, in any case, I will go to the Internet through the provider; I mean accessing the target resource through a proxy.
How can I ensure that only I and no one else can use this proxy? On the VPS with Nginx, 3 ports must be open - 22 (SHH) and 80, 443 (Nginx). I generally know how to protect SHH.
Is it possible to make the proxy pass only to certain sites and nowhere else? Is it possible to limit the range of IP addresses from which the proxy will accept an incoming connection? Is it possible to password protect the proxy so that only I can use it?
And where are the appropriate settings made - in the configuration of Nginx itself or in iptables or somewhere else?

Is it possible to password protect the proxy so that only I can use it?

nginx password

Answer 2

Isn't it easier to create a tunnel over ssh?
ssh -D 8888 -q -C -N [email protected]_vps
Then write the sock5 proxy localhost:8888 in the browser and your browser starts surfing the Internet through vps

Answer 3

Yes, you can on all counts. Google, read mana - trivial questions.

In general, Nginx does not really exist for this. Unlike Squid or SOCKS5 as fluffybear wrote

ssh -D 8888 -q -C -N [email protected]_vps
