Thanks Joe, I think I've understand (what I misunderstand before :)).

So: a LVS box, with NAT, tuned with parameters from that page can handle
(with enough RAM and CPU Power, of course) even 1 millions of total
connections (total connections = [connections originated from the
internet -like clients-] + [connections originated from the dmz -like
smtp sessions from mailservers-]).

Is it right?
If it so, thanks. My original question was: how many connections may a
lvs/nat can handle?
Enjoy your freedom
