Let me make sure I understand your architecture correctly:  Your first
tier system (192.168.1.12) is running the Java VNC client in a web
browser.  It gets the Java applet from an apache server on 192.168.1.2.
Xvnc (possibly launched by vncserver) is running on 192.168.1.2, your
second tier server.  Your third tier server (192.168.1.7) is running the
target application, and it is displaying to Xvnc on the second tier
(DISPLAY=192.168.1.2:1) which redirects to the VNC client.

The 192.168.1.7:1043  >  192.168.1.2:6001 connection looks like an X
application displaying to Xvnc on the second tier.  Xvnc is probably
still running after the VNC client disconnects, and there is still
traffic between it and the third tier application.  This would be
perfectly normal, although most applications wouldn't generate a great
amount of X traffic while there is no user input.

Or was my interpretation way off?
