Using Remote Desktop Across Internet With Firewall Protection

I have a laptop and have it configured to use Remote
Desktop while I am at home across my LAN but would like to
also be able to do this from another location. I would be
using the internet to do this and at home I have a router
which will have a built in firewall. Is it possible while
traveling to connect to my desktop using remote desktop
even though this firewall is present.

If possible to do could you give me a clue as to how to
find the computer via the internet.

Thanks,
Dave Marden
 
Forward TCP Port 3389 through the router to the private LAN IP of the desktop you want to Remote
Desktop to. Call using the public IP of the router.

Although what al suggests is possible, it is not terribly secure. I would setup the home pc to accept VPN connections and map port 1723 to it from your router. (This assumes your router has no VPN capabilities.) Then, you could connect your Remote Desktop. Both solutions require a static IP or a Dynamic DNS setup to ensure accessability from anywhere.
 
Well, the Remote Desktop data link is also encrypted...

....so...I don't see the need for a VPN to simply do Remote Desktop... Now if you want to access
multiple Remote Desktop sessions, then a VPN is a good idea, simply because you only open one port,
ie. TCP Port 1723 as you mentioned, versus multiple ports for multiple RD sessions...

Not to beat on you, but RDP between XP hosts uses precisely the same
encryption as a PPTP VPN link between the same hosts. Running within a VPN
tunnel does add another layer of safety, and the RDP protocol is susceptable
to one kind of attack which the VPN helps avoid--but using RDP directly
isn't unreasonable unless your application requires the strictest standards,
in which case a PPTP VPN isn't going to cut it either.
 
How do you do this?

What router do you have? With that information perhaps someone here can help with forwarding.
Alternatively, look at the users guide or the manufacturers support pages for help with "port
forwarding". Sometimes this is called "virtual servers"...
