Untangle’s Firewall filters traffic based on IP address, protocol and ports and allows administrators to designate which systems and services (http, ftp, etc.) are publicly available, create a DMZ and perform NAT (with Router), and run as a transparent bridge to complement existing hardware.
Untangle is much more than a firewall. It is, in fact, a Linux distribution that includes a host of software written by other developers. Software includes a Web Filter, Spam Blocker, Spyware Blocker, Virus Blocker, Phish Blocker, Instrusion Prevention, Attack Blocker, OpenVPN, Router, Untangle Reports, and Untangle Platform.
