Re: NAT and RDP ?

Kris, let me put some of this to rest,...you cannot make a "u-turn" through a
NAT device from a Client on the private side of the LAN. The way NAT functions
will not allow it,...the NAT editor creates a situation where both the source
and the destination MAC address are the same address, causing it to have sort of
an identity crisis, shoots itself and fails.

A host on the private LAN will access the resource by the private inward facing
ip# of the Server. External users on the Internet access the Resource via the
Public IP# which is NATed back the the Private IP#.

If the Resource is bound only to the Public IP# of the Server (like IIS can do
with websites) then there is no NAT happening to begin with concerning that
particualr Resource and users, no matter where they are from access via the same
IP#.

Hope that helps clear some things up. I do have a referrence for the NAT
situation involving the mac address but it is tedious to read.

Sorry if i was not clear.Let me explain the scene.
I have two desktop clients with the addresses -124.x.x.130 and 124.x.x.154 .
I also have a windows 2000 server with two nic cards ,One is configured to
have 124.x.x.129 and other one to have a 210.210.x.x

And the one nic card in the win2000 server that is configured with
124.x.x.129 is not mapped to any gateway.the gateway is left blank.
And the other nic card with 210.210.x.x is configured with proper gateway
(210.210.x.x) . And I also followed the URL
http://support.microsoft.com/kb/299801
for NAT in the win2000.


Now if i request the RDP session from the two address(124.x.x.130) to
124.x.x.129 I get connected to that Win2000 Server and able to browse but if
i examine the output traffic ,I find all the request to be of single ip that
is the 210.210.x.x. Will the client ip be NAt-ted when i request the RDP
Session since i have configured the NAT.Or Is there any way to assign Public
ip address for each of the client that is access the win2000 server through
RDP .Sorry If i am not clear this time also.Please reply me so that i can
eloborate more on this.


Thanks for your valuable reply.

I am not sure that I follow you. Where is the server you are trying to
connect to? If you are trying to connect by RDP from a workstation on the
private LAN to the W2k server which is running NAT , public IP addresses do
not come into it. You connect to the server's private IP.

If you are trying to connect by name and that name is resolving to the
server's public IP, you need to modify your local DNS to point to the
private IP..
