(help)-Remote desktop not working from "outside"

[straytoasters]

XP-pro/SP2.

Remote Desktop is enabled and I can login to "machine1" from another machine on my in house network if I use "machine1's" 192.x address but if I try to use the ISP assigned public address the address can never be found, even if I try from the same machine the the 192.x works on. 3389 is port forwarded to the correct machine. The public address is valid as I CAN remotely access my tivo, but that is port 80 (yeah, unsecured...I'm a slacker). This has worked before, like a year ago, but wont work now. I need to get around to testing VNC, to make sure it is not just a Remote Desktop issue. Any other thoughts?

so traffic destined for port 3389 is correctly forwarded to the ip of the machine, and remote desktop is enabled on the machine? also check if it is added as an exception in the firewall

this should definatly work if you have all this correct

You could also change RDP to listen on a different port (forwarding that new port from the firewall to your box) to see if that works - your ISP could be blocking 3389, or there could be packet size issues, etc.
