"i keep getting bounced from the list" - fyi I have installed ISA Server as a content filter tool for our school system. From our ISP, we get N2H2 filtering. The gateway and proxy are currently set for the ISP's proxy. I would like to place the ISA Server between the school's PC's and the proxy, as a second layer of filtering (if it's possible). This way we can block sites in addition to the sites N2H2 is blocking. Is this possible? How do I configure???
