setting up remote access to my home network to access from another site

ok i concede i have no idea what i am doing and need the assistance of a network VPN remote desktop expert
So the set up is a follows
I have a thompson st536 modem router and have gone through the throws of setting up a remote desk top on the system it has the remote access enabled with the URL  http://61.68.xx.xx.xx:51003 when you go to the router address
if i do a myisp it comes back the same as the modem
If i ipconfig the comp it comes back with  
IP address  192.168.x.xx
default gate way   192.168.1.2xx
 I wish to have access from my vista machine to the Acer in my home office -- I have xp pro installed on the office machine and its using xppro , and have just gone through the http://www.publicvpn.com/support/Vista.php
and set up vista as per the sheets but at the moment am a little bit confused whether I need to be using the ip address the router address or what any help would be appreciated also it is a dynamic ip address so i am guessing this will change as well, but just need to get it going first
thanks in advance

The Vista article is not related to your issue. You do not want to create a VPN, I suppose, but directly access your home office PC using Remote Desktop/Terminal Services.

What do you get when you "remote access" the modem IP with port 51003? I would expect you get to the config pages of the router then.

For a simple RDP (Remote Desktop) access, you need
  1. either a static public IP or a DynDNS service like dyndns.org (free) to register a name for the changing public IPs
  2. a static IP on your home office PC
  3. port forwarding from router to home office PC for RDP port
Point 3 needs to be configured on the router itself.


For easy access, you should instead consider to use a (in most cases free) service like logMeIn, visitMyPC aso. They allow for instant access to a single computer without the hassle of router configuration, IP address changes and alike.

If I turn off the modem and then back on then the url for the modem also changes to 61.68.1xx.xx:51003 so may need to look at a static or whatever but just need to get it set up

The remote PC registers itself at some server, and that server is asked for it's actual IP.

I've had good experiences with logmein. I recommend it. I use the free version to manage about 14 systems.
