What is a screened subnet architecture?
A screened subnet (also known as a “triple-homed firewall”) is a network architecture that uses a single firewall with three network interfaces. Interface 2 connects to a DMZ (demilitarized zone) to which hosted public services are attached. Interface 3 connects to an intranet for access to and from internal networks.
