IP Filtering in Windows 2003 Server

I have a Windows 2003 sat on the LAN. On the LAN is a ADSL modem router
conencted to the internet.

The Modem/Router does not support IP Filtering so I am left trying to
get the Windows 2003 Server to do so.

What I require is this:
From my home internet connection IP address (for example) 1.2.3.4
Click to expand...
Remote Desktop to the Server at 4.3.2.1

I have port forwarded 3389 from the modem/router to the servers IP
address, and everything is connecting fine, every one on the net
literally.

How can I tell Windows 2003 to only allow access to RDP from the LAN ip
range (192.168.1.0/255) and also my IP address 1.2.3.4

Is this at all possible with out thirdparty firewalls etc?

Thanks.
 
You may want to use Windows NAT. If this is the case, you need two NICs.

NAT and Firewall
In the Select Routing Protocol dialog box, click NAT/Firewall, and then click OK.
.... NAT/Firewall blocks the client accessing the Internet. ...

Hi,

The following may also be of use:

and

Securing Windows 2000 Communications with IP Security Filters, Part 2

I found the articles to be a big help.

Also, if you are printing (using TCP/IP ports on the local machine),
upgrade to RDP 5.2 (5.1 does not properly install the TCP/IP printer).
