ISA Server/Surf Control Web Filter For External Users

Hi All, my current setup is as follows: X1 DC with ISA2000/Surf Control Web Filter installed (will be changing these services to a dedicated server shortly!). Currently, internal users are forced through the ISA webcache/Surf Control Web Filter server using Group Policy and all works fine. For those users who are external to the domain I've opened up the relevant ports on the firewall/router which then means they can configure their internet browser on their home PC's and are then filtered in the same way as if they were on the LAN. My only question is this: is it possible to utilise the users OWN internet connection to download pages rather than all their traffic coming through my webcache. Currently, after specifying the proxy details in their own internet browser all requested pages are routed through my webcache server and if the page requested is allowed by the webfilter this page is then cached and passed on to the end user. I need to know if it's possible for them to have their web page request inspected by the webfilter though if allowed to then have THEIR OWN internet connection download the page rather than it coming through my server. Any advice greatly received. Marko

Thanks. We'll let you know when a new response is added.

NO. If you want the filter then they have to use the cache. If they download direct, then no cache AND NO filter.

Since th filter is licensed software, you can look at other alternatives for filtering those home clients, or see if they have a group license and clients for laptops, home systems.
