Remote Desktop error "http Endpoint Exception:4, the non-proxy http connection failed to connect with the message: 501 not implemented"

I am trying to control a Windows 10 PC from a Mac.  I have installed Microsoft Remote Desktop on Mac OSX.  I can successfully connect to the PC and control it from within my home network, but when I try to control it over the internet I receive the above error message (in the subject line).  My network configuration is simple.  I have a wireless router whose address is 10.0.0.1, and the ip address of the PC I am trying to control is 10.0.0.69.  I have determined my public ip address and entered that in the "PC name" field of  the Remote Desktop dialog.

I have followed directions to port forward port 3389 to ip address 10.0.0.69 in my router.  Is this correct?

Also, I am confused about the need for a "gateway" in the setup of RDP on the mac. In the gateway setup, I specified that the Server name is 10.0.0.69.  Is this correct?  Should I need to have a gateway configured?  If I leave Gateway unconfigured, I receive a different error, namely "Unable to connect to remote PC.  Please verify Remote Desktop is enabled...."

Can anyone help?
