Remote Desktop through ICS

I'd like to be able to connect to one of my home
computers from work using remote desktop.

My home network is set up as follows:

DSL Modem connected to Windows XP Home desktop.
Using ICS, the DSL is networked to a wired XP Pro desktop
and a wireless hub which shares to 2 wireless laptops.

Shouldn't I be able to set the ICS on the Host desktop to
take incoming remote desktop data and filter it to the
wired desktop? I've tried telling the host computer
that "CHRIS.MSHOME.NET" is the XP Pro desktop that the
remote desktop connections should be redirected to. I
assumed that this was done by going to the DSL modem in
Network Connections, clicking on the DSL Modem, going to
Advanced and Settings.

Am I doing this wrong? Is it possible to connect to a
client computer on my home network from my computer at
work via the internet?
 
Sure...ICS/ICF has an entry for Remote Desktop that you check the checkbox to enable port forwarding
on TCP Port 3389 to the private LAN IP of the XP Pro box. To call from work you need the public IP
of your home PC. So you need two things, the private IP of the target PC and the public IP of the
ICS PC. You can look at this small page that illustrates this. Modify as needed for your
situation...Note the use of static IP addressing on your local private LAN is recommended. DHCP
assigned IP addresses can change if you reboot/restart a PC negating the port forwarding scheme you
have setup in ICS/ICF...

If your ISP assigns dynamic IP addresses, and most do, then that IP probably will change every time
you reconnect to your ISP. You might consider using one of the dynamic DNS services that map an
alias, usually of your choice, to the IP address. Then you would call using the alias. I use a FREE
service from No-IP.com for this. Go to http://www.no-ip.com for further details. Others, some free
and some $$$$, are listed on this page...

You could then use the alias to call your home PC from work.

Example:

youralias.noip.com

Note that this also assumes your work does *NOT* block TCP Port 3389 outgoing...

Al,

I face the same problem and understood your setup. But what next?
I know the (dynamically assigned) IP-address of the ICS PC and I
know that my PC in the home network has the IP address say
192.168.0.3.

On the page for the 'Remote desktop web connection' I have to
enter the server. There I have always used the dynamically
assigned ICS IP address. But what should be entered here now to
access the 192.168.0.3 PC.

It depends on where IIS is running. If IIS is running on the ICS box, but you want to access a PC
inside your network you need to put the private LAN IP of the target PC in the server address field.
If IIS is running on the target PC simply leave the server address field blank. Note that since your
trying to use the web based method of access to Remote Desktop that you also need to forward TCP
Port 80 (IIS) to the IP of the IIS box. Also note that some ISPs block TCP Port 80 if they do *NOT*
allow web servers on their network.

Thank you Al. Now I understand the thing. I managed it to
establish a VPN and afterwards use the Remote Desktop with the
target PC address. Great :)
