arno-iptables-firewall (8)

/etc/init.d/arno-iptables-firewall [start|stop|status|force-reload|restart]

arno-iptables-firewall is an iptables configuration script with support for both IPv4 & IPv6. While it is extremely easy to use one can nevertheless use it in quite complicated environments.

All available options are explained in the extensively documented configuration file.

The external interface of the system needs to be set up properly in the firewalls configuration file (EXT_IF). The default behavior of the firewall is to deny all incoming connections.

For additional requirements not covered by the configuration file custom iptables rules can be placed in /etc/arno-iptables-firewall/custom-rules. This file is automatically parsed by the service script.

See the README file (eg. in /usr/(local/)share/doc/arno-iptables-firewall) for an example how to manage logging of firewall events through syslogd.

The arno-fwfilter script can be used to make the firewall logs more readable for humans (see manpage).

Several plugins for the firewall script are available online. Plugins can be downloaded from http://rocky.eld.leidenuniv.nl/ Please see the README file for more information.
