PBR to ISA 2006 Not Proxying Client Web Traffic

I have a ISA 2006 server set up with McAfee's Smartfilter software running to filter our organization's internet traffic.

In the past, we've had to enter the proxy setting into client web browsers. We don't want to do that anymore.

I thought I could just Policy Base Route clients' 80 & 443 traffic to the ISA server, and it would receive the traffic, run it through the filter, allow/disallow the access, and return either a block page or the desired webpage back to the client.

It is not working.

The question is, is it suppose to work? If so, what configuration settings am I missing.

I know for sure the PBR is working, because running WireShark on the ISA box shows that client traffic is getting to the proxy server, but then packets are being reset. So, it's something on the ISA server.

Would appreciate any assistance.

Thank you.

Create a new protocol using TCP port 80 outbound (rather than the existing http protocol) - use it in an access rule and disable the web proxy filter. Bear in mind though that this will treat the traffic as layer 3 rather than layer 7.

The ISA MUST be either the default mgateway or on the default route path to the Internet.
