How to correctly implement a connection through a proxy?

Question

linux

Hello everyone,
There was a task to create a proxy in this process:
There is a server inside the local network, it looks out through RouterOS with a white IP.
It is necessary, for a certain site, to change your white ip address (no crime, just a parser and a bot, in general, normal automation).
Is it possible to implement this using, for example, the same nginx ?
Or maybe it's better to do something similar in RouterOS?
Or are there ready-made software solutions in general?

Answer 1

To do this, you need proxy servers external to you. Those. you cannot just introduce yourself to someone under a different address - you need an intermediary with a different address through which you will connect.
You can look for open proxies, or raise your own on some cheap virtual machines. In particular, you can make them based on nginx, although there are many more suitable specialized forward proxy servers.
