It has been asked before and answered too. Have you checked the archives? I
recal recently answering a similar question.
Watch out for used ports: they cannot be used twice, that will cause
vnc uses ports in 5900, 5800 and (Unix/X11) 6000 range:
5900 (add display number for real port) is for the rfb protocol (the vnc
communication, you want this)
5800 (add display number for real port) is to serve the java applet, you
don't need it if you use vncviewer binary.
6000 (add display number for real port) is for Unix/X11 communication, only
local communication, you don't want this trough the firewall.

Scan the archives for details.
First setup a local situation using port 21 (most likely not to be used).
Don't bother the route trough the firewall (inbound or outbound), the
restrictions are most times the same, if not, outbound is lighter/easyer to
