You have to set
GatewayPorts yes
in /etc/ssh/sshd_config and be sure port 5050 is permitted by your host 
firewall to allow this forwarding to work for other hosts on the home 
side.  You might also have to specify the interface to bind to. Try 
connecting with putty from the windows box to test it.

You might find it easier to run an openvpn tunnel.

In the NX client on your windows box, set the host address and port to 
use the tunnel you have set up - and install the correct client key if 
you are using freenx and it should work.  As long as you don't check the 
box under 'advanced' that says 'disable encryption of all traffic' 
everything should run through its internally set up ssh tunnel (which 
shouldn't care that it is running through your reverse tunnel_.
