I'm using the firewall client on all of my client machines and we also use
ISP provided POP3 from the internet. Everything works like a charm. My
opinion, which may be different than the list, is not to have all clients
secure nat to the ISA. All of my clients have a default gateway set to my
cisco router.
If you have more than one physical location that is tied into your network,
making the clients secure nat to the ISA is BS and will cause headaches. If
you do this then you're left with using the ISA as a router for intra office
communication.
My philosphy is this, clients behind the inside (south) nic in the ISA should
have the FW client installed or their web browsers manually pointed to the IS,.
and their default gateways pointed to a cisco router. Servers that are
published through the ISA should only be your only secure nat clients,
especially in in a DMZ setting.

Is it really preferable to make all internal clients SecureNAT instead of
using the firewall client? It would seem that a Windows 2000 box would be a
greater point of failure than a Cisco router. Ours has been down twice now.
Once as they fan went bad on the Compaq DL 360 and once as the power went out
on that UPS. In both cases the Exchange servers that we publish use the ISA
server as SecureNAT and the entire company was shut off from mail. If the ISA
server is the def gateway then if it goes down not much will get done by ALL
internal clients, right? Is this the list view of a best practice (all internal
SecureNAT)? I am just curious as to the thinking.

First, if you use the firewall client to this purpose, uninstall it.
All client machine should be SecureNAT Clients (Default gateway should be
internal IP address of ISA Server)
create a protocol rule called (for example) allow Outlook Express, select
smtp and pop3 protocol and appy to
IP addresses of these computers.
Create a site and content rule with the destinations of mail servers....
Hope this Help,
ALEX
