Whether or not you use a default gateway depends on your own preferences and
environment.  A default gateway is not necessary.  Yes, hardcoded gateways
should enhance security.  OTOH, if you have 1100 sessions coming from over
150 subnets (internal and external) this adds another administrative job and
there are other ways to provide security.  My problem was that I depend on
the default gateway for most of my connections and it stopped working with
PP4 until I cleaned up my configuration.

                I'm confused, I don't understand why NOT having a default
gateway is a
                problem.  The other side of the coin is having hardcoded
gateways which
                should still work and enhance security.  Or am I going down
a merry path?
