Hello All,

Network Address Translation is the ability to translate from a series
(pool) of public IP addresses to private Ip addresses in a one-to-one
fashion.

From my experience, and from reading material, ISA's implementation of NAT
ir really PAT. Where the ISA server maintains a table of port to IP
addresses, i.e. a Socket table.

The reason for the question is because there is no way to assign a pool of
IP addresses within ISA as you can within RRAS. The NAT configuration is
not exposed anywhere in the ISA MMC interface.2 -

Thanks.

Nathan Sutton.
