Hello,
Well perhaps the internal clients are already using routable IPs Perhaps I
want a firewall without NAT. Other firwall products such as Checkpoint can do
both NAT and Routable IP. I was just curious if ISA could do the same.

1 - ISA will always perform NAT from the LAT (said the cat in the hat, as he
swung his softball bat)
2 - Unless the internal clients are already using routable IPS, it won't
work, regardless of technology.
What's the point of trying to disable NAT anyway?

Hello,
"Normally" when you use ISA you have a private address space connected to the
internal network adapter. When a client wishes to make a connection to a
internet host this address is translated to the external interfaces IP (A
long way of saying NAT).
Is it possible to operate ISA with a "Public" or routable address space
connected to the internal interace and to no have NAT performed?
I am still wat to use ISA as the default gateway for all my internal hosts, I
just don't want any address translation. The packets would appear to be from
the internal clients IP.
Just Curious.
Bill
