Hi: I have setup a Windows XP system running WinConnect Server XP to provide traveling users with RDP access to Windows. It is working well however to enhance security I want to restrict RDP connections to specific PCs based upon their Ethernet card MAC addresses. Specifically, only laptops owned by the company to be allowed to connect via RDP. There is no feature in WinConnect Server XP to do this. Does anyone have a suggestion as to how to accomplish this? Perhaps some hardware device? Or some software program running on another comtuter which will forward port 3389 traffic only for PCs with a specific MAC address? Thanks for your thoughts! Phil
