Endian Firewall Community
Endian Firewall Community is an open source Linux firewall operating system that has been designed with "usability in mind" and is very easy to install, use and manage, without losing its flexibility. It is derived from the highly acclaimed and award winning Red Hat Enterprise Linux distribution.
The main advantage of Endian Firewall is that it is a pure "Open Source" solution that is commercially supported by Endian. It comes with a powerful, modern, easy-to-use and easy-to-configure web interface that includes the Base, Advanced Antivirus, VPN Gateway, and Web Content Filter modules.
Features at a glance
Key features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, POP3, SMTP) with antivirus support, virus and spam filtering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN).
In addition, the distribution provides strong security for both your local network and the Internet, will secure your email, multi-WAN with failover, routing, Network Address Translation (NAT), reporting and logging, trusted timestamping, as well as most modern UMTS/3G USB dongles.
Distributed as a dual-arch, installable ISO image
Endian Firewall Community is distributed as a hybrid, dual-arch and installable ISO image, supporting both 32-bit (i386) and 64-bit (x86_64) instruction set architectures. The ISO image has approximately 200 MB in size and can be easily deployed to either a CD disc or a USB thumb drive of 512MB or higher capacity, which can be used to boot the operating system from the BIOS of a computer.
The distribution must be installed on your computer in order to use it. For this, you must have basic knowledge of installing a Linux kernel-based operating system from the command-line. Be aware though, that your current OS will be erased and you will lost all you data, so make sure that you backup your files first.
