<p>Here's a screen shot of my Network Options Configuration:</p>

<p>While not all of the options that I've selected are required, they should
be sufficient for most applications. Here'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):</p>

<p>Here's a screen shot of my Netfilter configuration:</p>

<p>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 I recommend that you modularize FTP Protocol
support.<br>
