<title>PPTP Client running on your Firewall with PPTP Server in an ADSL
Modem</title>
<para>Some ADSL systems in Europe (most notably in Austria and the Netherlands) feature a PPTP
server built into an ADSL <quote>Modem</quote>. In this setup, an ethernet
interface is dedicated to supporting the PPTP tunnel between the firewall
and the <quote>Modem</quote> while the actual internet access is through
PPTP (interface ppp0). If you have this type of setup, you need to modify
the sample configuration that you downloaded as described in this section.
