Thanks, with your help I'm almost there. I managed to get two external ssh 
accounts. from there, Lynx retrieves the pages fine and the round robin seems 
to be working perfectly ( surprise! ).  What does not work and what I can't 
verify in anything but a browser to my knowledge is the loading of images as 
I previously mentioned. In http GUI clients ( I've tested with mozilla, 
netscape and konqueror ) the additional connections to fetch images 
eventually get dropped unexplicably.  Browsers do not seem to trigger exact 
weighted round robin scheduling, but I presume I am observing the effects of 
persistent connections... But that wouldn't explain why lynx clients 
demonstrate true wrr and GUI ones don't !

As for taking the LVS out of the setup, I can connect to the real servers 
from inside my LAN and all the images load ( all connections are made ) 
flawlessly.

I would like to point out again, that this problem does not exist in my https 
cluster. I do no know why :(

Cheers,
