That's the key - ISA 2000 and RRAS share the same hooks in ipnat.sys and
it only allows one component to grab that hook at a time.

I would have thought that ISA would grab the stack before the RRAS NAT 
service could get hold of it, similar to its behavior of ignoring Basic 
Firewall settings where one tries to specify inbound or outbound
interface 
filters via RRAS on an ISA box.   Are you saying that ISA will share NAT

with RRAS?
