How to use multiple IPs if the proxy service only allows one?

Question

ubuntu

There is 1 server with ubuntu desktop and add. Software that works through a proxy. The proxy service itself allows only one server IP to be used.
If you create 2 similar server, can you somehow broadcast this second one through the first one, which in turn will go to the proxy server already through its IP?
2s -> 1s -> proxy server -> target The
question is that the second server with a different IP should work normally through a proxy. Is it real to do?

Answer 1

The proxy hides its client (IP and other attributes) from the service. Including from the next proxy in the chain. Therefore, under its IP 2s will no longer work. IP proxy looks outside.
