IPCopIpCop is a firewall software based on a Linux distribution that aims to provide a simple and configurable hardware firewall using a standard PC. Initially, it was a fork of SmoothWall IPCop. Later development has followed different paths and now the two distributions differ greatly.
IPCop is licensed under the GPL and is developed with the traditional style of Open Source: the project is developed through the collaboration of several developers scattered around the globe. The graphical interface is available in 17 different languages​​. The distribution also includes an elegant and simple system upgrade.
Although not entirely official dichiatati for IPCop, there are plenty of addons, developed by large software companies, which add extra features of IPCop, such as advanced QoS, e-mail virus checking, traffic summaries, extended interfaces for controlling proxy, and many others.

Technical features

IPCop offers a wide range of technical features, ranging from standard Linux netfilter capabilities of NAT support for DNAT DMZ away from supporting DHCP (client and server) to support and serve NTP to synchronize the date and time, the ability to activate a proxy to enable an IDS. It also supports four network cards and an unlimited number of VPN connections, as well as offering the possibility to backup and restore of the configuration. It is also easily extensible with many modules available on the Internet.

IPCop does not require much computing power to work: just a 386 little RAM and MB HD, but to do more configuration is required as a minimum a Pentium MMX with 64 Mb of RAM and a few GB of hard drive. If you plan to use the proxy functions are recommended 256 MB of RAM and a few GB free. The installation options range depending on your needs: street CD (it requires a reader) via USB key (requires an opportunity for booting from USB port), or directly to Compact Flash Card (must be an appropriate hardware).

IPCop appointment and diversified network interfaces in color. Here are the meanings:

  • RED – the interface is connected to the Internet. (Commessioni ISP – PPPoE – PPPoA, xDSL Router)
  • GREEN – is the interface for the internal network. (Private LAN)
  • BLUE – is the interface for a second internal network or a wireless network. (WiFi)
  • ORANGE – is the interface for any DMZ where there are servers that offer services outside. (Demilitarized Network)

The minimum configuration includes two network interfaces: RED (Internet) and GREEN (to protect the internal network), but it is not difficult to extend these steps to configure a firewall complex. If there are two local networks that should not be separated using the interface BLUE. Special features of IPCop is the ability to expand and add features. For many distributions that are created with special addons.
