Hello everyone, I’d like to set up remote desktop for the work computer of a relative of mine (Her employer gave me permission to do so). I am unsure about the best way to go:

• Should I try to enable port forwarding on the router, make them choose a strong password, and use the built-in Windows service?
• Or is it better to use a free (as in price) external program? My main candidate was Rustdesk, but after a bit of searching I found some controversies, what do you think about it?

If necessary I can resort to a closed-source solution.

Thanks to you all in advance.
