Reducing bandwidth use

Server Owners

Hello,
I have a 500 players server and use external voice server and resource caching server. How can I save some bandwidth on the main RP server? We have bandwith daily around 3TB. We use a lot of assets, but I think it should be handled by the CDN server.

Cfx.re Platform Server support proxies, read this tutorial:
Proxy Setup - Cfx.re Docs

I run the resource caching, is the proxy for saving traffic as well?

Will it save more traffic than using just the file server?
