Then you optionally preserve the IP address of your clients using for example on NGINX set_real_ip_from and real_ip_header.
## Warning
Adding an extra layer like a proxy server **will** add more latency, thus increase the response time from your final server to your browser. That's why for the part where you are going to rent a proxy server, you should choose a server close to your existing server(s).
It should be noted, in the 4th step of the instructions, you will be able to remove this latency for a major part of the users of your instance (around 90% - people using modern browsers). The rest will experience this *added* latency which won't result in a decrease of the user experience if you choose your server wisely.

TL;DR: If you have "unlimited" bandwidth limit it's much better.
- 1 CPU core.
- The proxy server should be close to your existing server(s), for minimal latency overhead.
??? note "You can monitor the bandwidth usage of your servers using vnStat."
