About the router set up for Desktop Remote (from outside to Home desktop)

[Andes]

Hi all,

It will be great to have your help on the router setup for Desktop Remote.

I would like to remote my desktop at home from outside.

I have already set the port mapping in router, i.e. 3389 and 5900.

Meanwhile, I have already set the DDNS, NAT/DMZ (point to my desktop).

But, the PC still cannot be found.

Thank you very much. 🙏
