<para>This document is meant as an introduction to how to setup a
|
|
|
|
|
firewall - it is not a complete guide to securing systems. Firewalling
|
|
|
|
|
is a complex issue that requires careful configuration.
|
|
|
|
|
The scripts quoted here are simply intended to give examples as to how
|
|
|
|
|
firewalling works, they are not intended to fit into any imaginable
|
|
|
|
|
configuration and may not prevent any imaginable attack.</para>

|
<para>The purpose of this text is simply to give you a hint on how to get
|
|
|
|
|
started with firewalling.</para>
|
|
|
|
|
|
|
|
|
|
<para>Customization of these scripts for your specific situation will
|
|
|
|
|
be necessary for an optimal configuration, but you should make a serious
|
|
|
|
|
study of the iptables documentation and firewalling in general before hacking
|
|
|
|
|
away. Have a look at the list of <xref linkend="postlfs-security-fw-library"/> at the end

of this section for more details. Here you will find a list of URLs that
|
|
|
|
|
contain quite comprehensive information about building your own firewall.</para>
