Not sure what your asking...are you asking how to do this? If so, checkout the learning zone articles on DMZ scenarios at www.isaserver.org Basicly, there are 2 ways to do it, trihomed or back to back. I always suggest back to back, but this requires 2 ISA servers. If you just have 1, then trihomed it is. Unfortunatly you need to split your IP range up for this, to assign some to the DMZ and some to the external card of the ISA server. Anyway, try it according to www.isaserver.org and post back if you get problems.
