You should also look into publishing TS on a port other than 3389.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal
Server\winstations\RDP-TCP
Edit the key Port Number to enable the port you wish to connect to.
If you change the port to be 45535 just type the following into your
favourite TS client:192.168.1.1:45535
Rdesktop supports this from Beta 1.2 - any MS TS client will accept this
format.
You may also wish to do a search at www.securityfocus.com and search for
securely publishing Terminal Servers. There was an excellent article
that covered most situations but I've mislaid the link. Options included
encrypting the stream from custom port to custom port via zebedee which
is a small encryption program.
Hope that helps your friend a little
