Route RDP to more than one NATed LAN address without changing from use of Port 3889
Posted on 2007-07-23
How can I route RDP to more than one address inside my LAN, which is behind a Netgear FVS318 firewall with NAT enabled? I have SBS 2003 which, from my understanding, requires port 3889 to be mapped to it. Additionally, I am attempteing to deploy a separate terminal server in my SBS domain on the same LAN, and have it use the default port 3889 for RDP connections.
Apparently I cannot get this to work with the Netgear firewall/router because when I try to use the firewall adminn console to add an additional routing for 3889 to the terminal server nothing happens when I submit the new routing. (I am assuming this is because 3889 is already mapped to the SB Server.) Maybe this is just limitation of the Netgear firewall, and would function differently with a more sophisticated appliance?
I am aware that the port for RDP connections can be changed to something other than 3889 by tweaking the appropriate reggistry values, but I would really like to stay with the default on the TS and am extremely reluctant to change this on the SBS.
