Protect admin page using proxy

Question

I want to protect my admin page not only with a login and password, but also with IP filtering as described here: https://security.stackexchange.com/a/30649/68841

But I have two questions:

1. Can I use a proxy instead of a VPN?
2. I also need to use one more proxy on the server, for API requests to the specific site which blocked in my country. Can I use the same proxy to access the admin page on my server and for the API requests from this server to another site?

Answer 1

Yes, you can use a proxy. Your two questions will answer with one application, you need to set up this. You can use NGINX.

NGINX is opensource software for web serving, reverse proxying, caching, load balancing, media streaming, and more.

Here's my answer to your questions:

1. Yes you can use nginx proxy to protect your admin panel, Here's the link https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/

2. You use Nginx proxy again in the same server, what you need to do is setup a virtual host or server Blocks and proxy pass if you want to other api to your domain https://www.nginx.com/resources/wiki/start/topics/examples/server_blocks/
