[FreeNX-kNX] Firewall / Port forward - NX Server

[Doug Burks]

I would focus on getting SSL encryption to work.  Here's some things to try:
1)  Have you tried a different client?  Does NoMachine client version
1.3.2-7 do the same?
2)  It sounds like you have a firewall with one public IP address
providing NAT for the LAN that houses the FreeNX servers.  Do you have
port forwarding configured on the firewall to forward a specific port
on the firewall to SSH on one of the FreeNX servers?  Like this:
Firewall:23 --> NXserver1:22
Firewall:24 --> NXserver2:22
Firewall:25 --> NXserver3:22
Is that correct?  Can you SSH to each of the FreeNX servers from
outside of the firewall (using, for example, Putty on Windows)?
3)  On your FreeNX server, did you change the port that your SSH
daemon listens on from the default of 22?  If so, you will need to
update the following option in nxserver to reflect the new port:
SSHD_AUTH_PORT="22"

Thanks,
Doug
