access home PC through RDP
Posted on 2007-10-10
I am attempting to access my home computer while at work using Remote Desktop. Both computers are running Windows XP Professional. I have a cable modem connection at home which is shared by multiple computers through a Netgear router. If I attempt to access the home computer from another computer on my home network, it works just fine. However, in this situation, I am able to use the internal IP address (not sure if that is what it is called) which is assigned by the router. So for example, I can use computer A (192.168.0.100) to access Computer B (192.168.0.103) and it works just fine.
Obviously, these IP addresses are not available outside of my home network, so what IP address to I use to connect to the target machine? I located what my external IP address is, but attempting to connect to that IP address fails. WIndows Firewall is disabled, and I have gone into the settings on my Netgear router and made sure it is set up to allow remote desktop connections.
Is there something more that I need to do? Also, today I am working from home and using VPN to access my work computer. Is testing the connection from this computer (connected through a VPN connection) a realistic simulation of what I will experience when I am at work, or is this just making the matter more complicated?
