This is the official release announcement for IPFire 2.19 – Core Update 104.
This update brings you a new kernel under the hood and a from scratch rewritten Guardian.

Linux 3.14.79

The Linux kernel has been updated to version 3.14.79 and brings you various bug-fixes, stability improvements and supports more hardware.


Gurdian is an Intrusion-Prevention-System that is hooked into Snort, the Intrusion Detection System. It reacts on reported events by blocking access for hosts where malicious traffic was detected to originate from. That enables IPFire to be a dynamic firewall and block any abuse or other unwanted behaviour automatically.

Since the old implementation was quite old and rather limited, Stefan Schantl started a complete rewrite which is faster, more efficient in resource usage and of course more reliable.

If you want to use Gurdian, you will have to install the guardian add-on package.
