<para>PPP has ability to use internal NAT without kernel diverting
capabilities. This functionality may be enabled by the following
line in <filename>/etc/ppp/ppp.conf</filename>:</para>
<programlisting>nat enable yes</programlisting>
<para>Alternatively, PPP NAT may be enabled by command-line
option <literal>-nat</literal>. There is also

<literal>ppp_nat</literal>, which is enabled by default.</para>
<para>If you use this feature, you may also find useful
the following <filename>/etc/ppp/ppp.conf</filename> options
to enable incoming connections forwarding:</para>
