Updates HE public IP records for your tunnel (for instance at the coffee shop), finds the first available interface that is connected and creates a v6v4tunnel using that IP.

See script for where you need to edit.

function fastpingtest {
    $ping = New-Object System.Net.NetworkInformation.Ping;
    $ping.Send("8.8.8.8", 1000).status -eq "success";
}
$endtime = [datetime]::Now.AddMinutes(1);
$mapipv6 = $false;
while([datetime]::Now -lt $endtime) {
    if(fastpingtest) { $mapipv6 = $true; break; }
}

if($mapipv6) {
    $wc = New-Object net.webclient;
    $url= "https://ipv4.tunnelbroker.net/ipv4_end.php?ip=AUTO&pass={1}&apikey={0}&tid={2}";

    $values = "USERID", "PASSWORDMD5HASH", TUNNELID;
    $wc.DownloadString(($url -f $values));
