With SBS Standard without ISA, and a TZ170, are you comfortable opening port
80, as well as the ports for OWA?Does the TZ170 do stateful inspection on an open port? Does ISA?
I know ISA is considered safe when having the standard MS web services open. But is the configuration of a firewall appliance and a server with 1 NIC equivalent to ISA and a server with 2 NICs?
