Strange thing about that.  When using a NAT hide rule FW-1 did not NAT the
ESP packets.  I saw private addresses exiting the external interface,
un-NAT'd.  Even though the UDP/500 packets _were_ NAT'd.

I believe FW-1 only knows how to NAT TCP, UDP, and ICMP.

This list has many times gone through why it is impossible to
do NAT on ESP in the general case. You cannot do many-to-one.
