Have you created an outgoing packet filter for port 80

        Hi all,
        
        I have just performed a basic installation of ISA with SP1 on a 
multihomed
        machine within our network.
        
        I can configure Packet filters to allow/deny certain ports and this all
        works fine. - Which would suggest that there is no issue with the 
routing
        or the IP configuration.
        
        However, for some reason, I cannot get anything using the Web Proxy to
        work and its starting to get a tad frustrating! - The ISA server has the
        default Allow rule for all Site and Content access and is using the
        default port of 8080 for all outgoing web requests, however everytime I
        attempt to access a site from the IE, using the appropriate Proxy 
settings
        I get an ISA error showing the following:
        
        *******************************
        HTTP Proxy Error - The ISA Server denies the specified Uniform Resource
        Locator (URL). (12202).
        
        Technical Information:
        Background:
        The gateway could not retrieve the requested page.
        *******************************
        
        If anyone can shed any light on this it would be very much appreciated.
        
        Cheers,
        Mark
