Integrating PIX525 with Microsoft ISA server

[lim.poonlee]

Hi,

Using ISA alone, I can restrict Internet access (outbound) to certain groups of authenticated users on my network. By using PIX525 as my firewall, how can I achieve the same functionality? (assuming that I am keeping my ISA server) Do I need to setup the ISA server as a RADIUS server?

Yes. You can use the cut-through proxy feature of the PIX to authenticate your users via RADIUS, using the Micorsoft IAS box. This can be applied to any interface, but in your situation it looks like you would apply this for outbound connections on the inside interface.
