There is no problem with that in ISA2004. As I understood it that particular 3rd party ISAPI (ISA2004 PROXY) plugin simply doesn't see URLs from SNAT clients (i.e. http traffic redirected to PROXY ) therefore it can not filter them and its passing them through. My conclusion from this was that 3rd party plug-in needs to be fixed as there is difference now how to get request URL from SNAT clients and direct proxy clients (I described this before in more detail) . Correct me if I am wrong.

I remember doing that in ISA2000, but where is this setting in ISA2004? ________________________________ From: David Farinic [mailto:davidf@xxxxxxx] Sent: Thursday, March 17, 2005 09:30 To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISAserver.org - Review of SurfControl Web Filter 5.0 for ISA Server 2004 http://www.ISAserver.org >Since the ISA server is the Default Gateway, it will probably then prompt them for authentication, which they will enter, and then be given access.

Maybe I am missing something here but why in this case they are not redirected to proxy filters by ISA http redirector? IMHO they should be always filtered by ISAPI filters unless u turn off somehow http redirector.
