Exactly! I got it. Thanks a ton. I did tunnel in reverse connection. :)
One last question: while going through Tiger VNC source code, I came to know
that it has inbuilt Tunneling support. Researching more on this, from
http://fedoraproject.org/wiki/Features/TigerVNC, I got the information that
it requires both client and server Tiger VNC.
*tigerVNC extensions (both client and server are tigerVNC):*
- optional JPEG compression
- Automatic SSH tunneling on Unix
Currently, we have VNC server from Real VNC latest version but we are
planning to migrate to Tiger VNC server. Could you tell confirm that if we
have client and server Tiger VNC then we don't need to do explicit tunneling
using above method?
Thanks.

Throughout its 18-year history, RSA Conference consistently attracts the
world's best and brightest in the field, creating opportunities for Conference
attendees to learn about information security's most important issues through
interactions with peers, luminaries and emerging and established companies.
