I need to configure isa server on my network. I've 3 servers (1 for firewall, 1 for web, 1 for database). Ne1 have documentation about configure network between their and isa server?
Put the ISA Server at the edge of the network. Put the web server on the DMZ between the Internet and your internal network. And put the database server on your internal network and create a packet filter on the ISA Server between your internal network and the DMZ to restrict communications to the internal database server so that only the Web Server can access it through the downstream firewall.
