HACK
On the third wizard page, you can choose your protocol type (the NX client
is also an RDP and VNC client), the type of desktop session to run the NX

“Enable SSL encryption of all traffic” box, as this tunnels all communica-
tion through SSH (i.e., you only need port 22 open) and has the added
bonus of encrypting all the NX traffic. If you don’t want to tunnel the traffic
over SSH, you’ll need to open ports 1000, 5000, and 7000 for the first ses-
sion, 1001, 5001, and 7001 for the second session, and so on—i.e., three
ports for each session started.
Finally, on the fourth wizard page, you can choose to create a desktop short-
cut for this session and edit the advanced configuration. Once the wizard is
finished, you should have a connection dialog with the Login and Session
details filled in.
Now type in the password you set on the NX server and click Login. Once
this connects and authenticates you should have a complete remote desktop
in a window on your client machine.
