        You can check http://www.linuxvirtualserver.org/docs/defense.html
You can play with secure_tcp and drop_entry. Probably, it is a
good idea for implementation, to enter nomem state also when
total number of the conn entries reaches user defined point because
the current way of depending on free memory is not always desired,
for example, if the director is used for other needs.
