It is my understanding that you must Port Forward 3389 in order to use
Remote Desktop via the Internet.

My questions - must you do this for both your router and the Windows
Firewall and must you forward both TCP & URL?

Since I'm running XP Pro on a LAN, must I include forwarding for each of the
pc's I want to access?

TIA

Port forward is only done at the router.  You just need to permit
Remote Desktop to "pass-thru" the firewall.

Also, it should be UDP and not URL.

Hi
Ports have be forward in the receiving computer (I.e. the one that is
controlled from the outside).
The forwarding has to be done through all devices, and software applications
that blocks ports. Typically it is the Router and software Firewall.

URL? No, I don't know what you mean. If you mean UDP, then no.
You can't do this if you don't have multiple public IPs bound to the WAN
interface on your router, and one to one NATs set up for each public to
private. Otherwise, you'll need to change the listening port for each
computer in the registry (e.g., 3390, 3391, etc) and make sure they're set
with  non-changing private IP addresses. Then set up custom exceptions in
each PCs firewall for those ports. Then set up a rule for each in the
firewall This is a pain - you might consider an SSL VPN appliance like the
SonicWALL or Netgear lines which will let you access your desktops via a web
page / menu, and none of this nonsense.
