I want to create the configuration necessary to do the following -
I have a remote machine which I need to RDP from to a workstation inside the local network. Let's call the IP of the remote machine SPHome. The machine I want to connect to is at 192.168.1.250. Let's call the public IP of my network MyPublicIP. And I want to use port 3390 for the connection. So I want to RDP to "MyPublicIP:3390".
So I tried to set up a rule to test the configuration and I named it RDPTest. It is shown below.
In the Mapping Rule section what is the difference between the Incoming Interface and the Source IP?
What else might I be doing wrong?

The NAT Source IP is the IP you are remotely connecting from to "MyPublicIP:3390" if you don't know the Source IP then set to ANY.
You will also need a rule in policy control for from WAN1 to LAN1 port 3389
Some changes you can do is if your External IP changes you can set for NAT external IP a address type as interface for WAN1. To make RDP safer the remote connecting PC can have like NO-IP then the policy control rule for RDP can have for Source a FQDN for the NO-IP domain so that RDP is not open to all.
