<title>Network Options Configuration</title>
<para>Here&#39;s a screen shot of my Network Options Configuration:<graphic
align="center" fileref="images/netopts.jpg" /></para>
<para>While not all of the options that I&#39;ve selected are required,
they should be sufficient for most applications. Here&#39;s an excerpt
from the corresponding .config file (Note: If you are running a kernel
older than 2.4.17, be sure to select CONFIG_NETLINK and CONFIG_RTNETLINK):</para>

<title>Netfilter Configuration</title>
<para>Here&#39;s a screen shot of my Netfilter configuration:<graphic
align="center" fileref="images/menuconfig1.jpg" /></para>
<para>Note that I have built everything I need as modules. You can also
build everything into your kernel but if you want to be able to deal with
FTP running on a non-standard port then you <emphasis role="bold">must</emphasis>
modularize FTP Protocol support.</para>
