If you build you own server on your home/office, and can't connect it through public IP/domain, please check [this article](https://rustdesk.com/docs/en/self-host/nat-loopback-issues/).
Lowest level VPS is enough for your use case. The server software is not CPU and memory intensive. Our public ID server hosted on a 2 CPU/4 GB Vultr server serves 1.5+ million endpoints.
To make life easy, we have developed scripts which take care of everything (install/upgrade/convert from open source) [Simple Install Script](https://rustdesk.com/docs/en/self-host/rustdesk-server-pro/installscript/).
Don't forget to get your license from [https://rustdesk.com/pricing.html](https://rustdesk.com/pricing.html), check [license](https://rustdesk.com/docs/en/self-host/rustdesk-server-pro/license/) page for more details.
Almost the same as [the open source version](https://rustdesk.com/docs/en/self-host/rustdesk-server-oss/install/), but you do not need to run hbbs/hbbr with any arguments. These can be set later in web console.
-`-r <server:host>` is not needed any more if the relay server runs on the same machine with hbbs, and you can set multiple relay servers in the web console
