Integrated Windows authentication fails through PIX

I regularly connect to an external website which uses IIS's Integrated Windows authentication (aka NTLM). When connecting to this site via a modem and dial-up account, IE6 prompts for a username and password. But when using the LAN connection, via a PIX 501, there is no prompt for credentials and the server returns HTTP 401.2 immediately.

Interestingly, if I set up the website to listen on port 8001 (or whatever) as well as 80, then it works fine through the PIX as well as the dial-up.

Can anyone shed any light on this? Thanks.

Re: Integrated Windows authentication fails through PIX

Are you doing user authentication on the PIX as well, so that a user has to authenticate to the PIX before being able to send outbound traffic? If so, see the "virtual http" command docs here:

No, I'm not doing any authentication on the PIX (as far as I'm aware) - I'm using it pretty much straight out of the box and there are no AAA commands in the configuration.
