Explanation

When Expressway-E is positioned in a DMZ between two separate firewalls - one facing the public internet and one facing the internal network - it sits on two distinct network segments simultaneously. A dual network interface (also called a dual NIC configuration) is required so that Expressway-E has one interface connected to the external (internet-facing) segment and a second interface connected to the internal (DMZ-to-internal) segment. This allows it to accept connections from external clients on one interface while communicating with internal Expressway-C or UCM on the other, maintaining proper network segmentation and firewall policy compliance.
