                       ●   Alpine
●   Alpine originally stood for A Linux Powered
    Itegrated Network Engine
●   On the other hand, there are a number of
    installations where Alpine Linux is used as the basis
    for enterprise servers running Postgresql, Postfix,
    Asterisk, Kamailio, iSCSI SAN. It is the little engine
    that could.

●   Astaro Network Security
●   Astaro Network Security includes fully integrated
    features such as a configurable firewall paired with
    an Intrusion Protection system, Denial of Service,
    lots of traffic forwarding and NAT tools and much
    more. Take a deeper look at the extensive range of
    features provided by this security application.

                      Astaro fw
●   Astaro’s firewall uses an object-based approach.
    Simply define an object like a workstation or
    company web server, and then re-use this
    information all through the configuration. Astaro’s
    firewall is intuitive

                           M0n0 wall
●   m0n0wall is a project aimed at creating a complete, embedded
    firewall software package that, when used together with an embedded
    PC, provides all the important features of commercial firewall boxes
    (including ease of use) at a fraction of the price (free software).
●   m0n0wall is based on a bare-bones version of FreeBSD, along with a
    web server, PHP and a few other utilities. The entire system
    configuration is stored in one single XML text file to keep things
    transparent.
●   m0n0wall is probably the first UNIX system that has its boot-time
    configuration done with PHP, rather than the usual shell scripts, and
    that has the entire system configuration stored in XML format.

04/17/2010 - m0n0wall 1.32 released
m0n0wall 1.32 patches an Ethernet bug on
ALIX boards (among others) and contains
several other small fixes and
improvements on IPv6, the DNS forwarder
and the hardware monitor.
