Is it still very counter intuitive to set up a PIX to _not_
do the eevul NAT? Is the PIX no longer PeeCee hardware underneath
(I know they got rid of the HDD) so not as to bring NOs down to the
level of the great unwashed throngs of desktop users?

At least Checkpoint had the sense to kill the FWZ VPN protocol
early and go with IPsec. More than I can say for M$. Not that
IPsec interoperability is fully realized. Checkpoint has its own
proprietary icky tricks to try to sneak IPsec through NAT just
like every other commercial vendor. But Checkpoint admins are
worst part, "I check the box to use IKE VPN but someone said that
uses the ESP service. Which port number is that? I read port 50
somewhere, but should I make it a TCP or UDP service?"

The Checkpoint feature/bug that frustrates me is at the GUI
level there is no association between a rule and an interface.
To cover up this problem, there is the automatic "anti-spoofing"
feature which is a bitch, if not impossible, to properly configure
for a complicated topology.
