IPFire v2.9 Core 51 Released.

IPFire is a source-based Linux firewall distribution that brings additional features with it. The easy-to-set-up system defeats its competitors like IPCop, Smoothwall and Endian-Firewall potty. A stateful-inspection-firewall with a luxuriant content-filtering-engine plus traffic-control (QoS) rounded with latest vpn-technology and a lot of logging is foolproof to administer with just a very few clicks.

So you can get anything out of IPFire you can imagine. Without any add-ons installed it is an ultra-fast firewall but can also be a full-featured home server. It's up to you what you want. Check it out...

After the first release of august 2005 the project relaunched an extremely flexible, stable and fast firewall, which was finally finished.

IPFire is new-developed firewall build with the latest releases of Linux 2.6 and tools. You are able to install a lot of add-ons and you will see a firewall can become a home server.

One of the highlight of this security accessories are the extensions to make a real home server out of it. You are able to install additional add-ons to the system with only a few mouse clicks. There are for example:

  • A fast fileserver for networks with Microsoft Windows
  • A local mailserver with virus scanning and spam detection
  • A multimedia-jukebox
  • A mp3- and ogg-streaming server
  • An Intrusion Prevention System plus Guardian
  • Voice over ip-solution with asterisk pbx

Changes since previous version:

This is the 51st update for the second series of the IPFire firewall distribution.

Core Update 51 is addressing several security issues in the Linux kernel as well as stability fixes, performance optimization and driver updates.

It is recommended to install this update as soon as possible and please take notice that a reboot is required to complete the installation.

The update includes the latest Linux longterm kernel of the 2.6.32 series ( and includes a lot of security fixes and driver improvements (see below).

A couple of years ago, there have been problems with some TCP/IP options so these options were disabled to cause less trouble. As technology has developed, these options have now been re-enabled which improves the network throughput a lot.

In the last minute, the kernel developers decided to change the algorithm that is used to generate the TCP sequence numbers (http://lwn.net/Articles/455135) from partial MD4 to MD5. Dan Kaminsky pointed out that the MD4 random numbers are not really random enough at all. The new algorithm improves security albeit not hitting performance too much.

List of the updated drivers:

  • compat-wireless (2.6.38-3-ns)
  • e1000 (8.0.30)
  • e1000e (1.3.10a)
  • igb (3.0.19)
  • v4l-dvb (git20110427)
  • linux-firmware (20110518)
  • zd1211-firmware.

Altogether this update makes IPFire running on more recent hardware and improves support for wireless interfaces.

We recommend everybody to update, soon and won't release any more updates for older versions of IPFire.
