If I understand you correctly you are trying to attach to a home network
from some other site. If that is correct, then you need to make the setting
change on your home router or firewall. Each vendor should have
instructions on their web site which explain how to forward a port. The
process itself tends to be fairly simple. All you have to do is forward
traffic on port 3389/tcp to the private IP address of the PC that should be
accepting the connections. If you let me know what kind of router or
firewall you're using I'm sure I can find the respective web site for you.
If you have multiple machines on your home LAN you can also always try
connecting to the private IP to verify that the PC is set up correctly. A
connection from one PC to another on your home LAN would not require any
port forwarding so long as you use a private IP address.
Kind Regards,
