    <!--
    "Friendly Technologies" provide software like L2TP and PPPoE clients to ISPs,
    who give the software to their customers on CD so they have less trouble setting up thire connections.
    They also provide remote configuration solutions .. not the best idea if you ask me.

    An overflow exists in fwRemoteCfg.dll provided with the dialer,
    an example of the dialer can be found here:
