A couple of people wrote to me recently about problems locating the ISA firewall sizing calculator. The new ISA firewall sizing calculator provides you a powerful tool enabling you to figure out how to size the hardware for your ISA firewalls and figure out how many ISA firewall of that size you need to provide secure inbound and outbound access control to and from your company.
To launch the ISA firewall sizing calculator, go to the main Microsoft ISA firewall page at www.microsoft.com/isaserver and click the calculator icon on the top of the page. That will launch the calculator in a flash window.
