I'm trying to connect to a windows XP box running IIS with Remote 
Desktop Web Connection on it.  I have IIS running on port 3390, and I 
can connect to it within the Lan and everything works correctly.  I can 
also connect to it from the Internet and I see the default starting page 
like normal but when I enter an IP address (192.168.1.110 for instance), 
it goes to the next page were it eventually times out.

Here are my applicable firewall rules:
TCP 	* 	* 	Server2 	3389 	NAT Remote Desktop to Server2
TCP   

	*
	*
	
Server2

	
3390

	NAT Remote Desktop Web Connection to Server2


Here are my applicable NAT rules:
WAN 	TCP 	3389 	Server2 	3389 	TS to Server2
WAN
	TCP
	3390
	Server2
	3390
	Remote Desktop Web Connection to Server2



The time out error message is as follows:
VBScript: Remote Desktop Disconnected
The client could not connect to the remote computer.  Remote connections 
might not be enabled or the computer might be too busy to accept new 
connections.  It is also possible that network problems are preventing 
your connection.  Please try connecting again later.  If the problem 
continues to occur, contact your administrator.


Does anyone have any ideas? Am I missing some configuration details or 
am I going about this wrong?

Thanks in advance!
