Shweet Jim!!!
Thanks for the clarification. There is no doubt that disabling the "Ask for
auth..." option is the best for me.
Cheers

Here's what happens:
1. SNAT tries to make a direct connection to www.kiddieporn.com
2. HTTP Redirector is set to "send to web proxy.."
3. Web proxy gets unauth'd request; responds with "407"
4. SNAT client responds with credentials as supplied in that annoying popup
5. HTTP Redirector strips the credentials (this is important)
6. Web Proxy responds with "407" (again)
..thus, you have three choices;
1. set the HTTP Redirector to "send to requested .."
2. disable the HTTP Redirector
3. disable "ask unauth..."

Aaarrghhh!!!!
Are you telling me that by enabling the "Ask unauthenticated users for
identification" option in the Outgoing WEB Requests I am effectively denying
all my SNat clients from HTTP-based web access??
Or is it only denying my SNat clients because I don't have an associated
Anonymous Protocol/S&C rule?
Well, I have disabled the above setting and it does now work, BUT, by doing
so, have I opened up any luvverly little holes in my ISA, or will the fact
that all my Protocol/S&C rules require user authentication (or IP Address
Auth for SNat clients) prevent any anonymous access through my ISA?
Cheers
William R.

Hi Bill (bill, bill, bill; gotta practice),
The biggest problem in this scenario is the "ask unauthenticated.." setting
in the Outgoing web requests listener.
This will force auth for all anonymous web connections regardless of the
rules in place.

Hi there
I have now the opportunity to allow a couple of *nix servers through my ISA
Firewall. So I tell myself:
"Self, it's no problem, simply change the default gateway of the *nix
servers to the ISA's internal NIC, create a new Client Address Set for the
relevant IP Addresses of the *nix servers and then create a new Protocol and
Site&Content rule allowing the specific Client Address Set through..."
Well, I can tell you that "self" is having some trouble with this and was
wondering if there was anything simple I was missing. To my knowledge the
above is all I need to do, but if someone can tell me any other tricks that
need to be done on the *nix servers regarding authentication, or some other
fancy ISA authentication modules I need to activate, I would really
appreciate it.
Cheers
William R.
