Project Description

NARC (Netfilter Automatic Rules Configurator) is a free firewalling package for Netfilter/Iptables, released under the BSD license. It attempts to simplify the setup of a firewall (stateful packet filter) via the iptables tools. It is a bash shellscript that generates (hopefully) sensible and secure rules for Netfilter based on a simple configuration file. It features quick setup via a simple configuration file, connection tracking (and fragmentation reassembly), customized logging, probe detection (TCP & UDP), and much more.

0.7

This release implements IPLIMIT so that it works with 2.4
and 2.6 kernels, implements port forwarding to other
interfaces (no longer limited to DMZ), fixes an error in the
install script that omitted a mkdir, and removes the TCP port
445 (microsoft-ds) from TCP_PROBE.

0.6.3

Even more sanity checking was added. A new
experimental install script was added. The default
logging level was changed from kern.=info to
kern.=debug in narc.conf. Please modify your
syslog.conf to accommodate the change. The
LOG_LIMIT_EXCEED option was added to log TCP
connections that exceed the LIMIT_RATE in
narc.conf.

0.6

The NARC executable path is now configurable (used by /etc/init.d/iptables).
NARC was rewritten to make adding future options easier. Support for general
rate limiting was added. Support for IP/network based connection limit (TCP
only) was added. More logging options were added (ICMP, packet length,
iplimit). General code cleanup and optimizations were made.
