Fortigate Webfilter Bloklanan Siteye İzin İsteme

Fortigate üzerinde webfilter bloklama mesajı ile karşılaşan kullanıcılar, yasaklanan siteye giriş hakkını isteyebilirler. IT personelini email veya telefonla aramak yerine kullanıcıların önüne bir form çıkararak, siteye girme isteklerini form aracılığı ile ilgili IT personeline iletmek daha kullanışlı olacaktır.

İlk adım olarak Config -> Replacement Messages alanından Fortiguard Web Filtering başlığı altında Fortiguard Block Page satırını seçiyoruz. Aşağıdaki varsayılan olarak gelen sayfa belirecektir.

Sağ tarafdaki html kod alanına aşağıdaki kodları yapıştırıyoruz.

Görüntü şu şekilde olacaktır.

fweb2Formun action kısmında içerde bir webserverin mail gönderen sayfanın çalıştığı link verilmeli. Test amaçlı PHP kullanılmış olup kodlar şu şekilde;

Mail gonderiminde kullanılan class.phpmailer.php dosyasını https://github.com/PHPMailer/PHPMailer adresinden indirebilirsiniz.

<?php
header('Content-Type: text/html; charset=utf-8');
require("class.phpmailer.php"); 
  $mail = new PHPMailer();

$ip=$_SERVER["REMOTE_ADDR"];

$body = "<b>IP :</b> $ip<br />";
$body .= "<b>Email :</b>".$_POST["email"]."<br />";
$body .= "<b>Web Adresi :</b>".$_POST["url"]."<br />";
$body .= "<b>Kategori :</b>".$_POST["cat"]."<br />";
$body .= "<b>Mesaj :</b>".$_POST["mesaj"]."<br />";
$body .= "<b>İstenilen Kategori :</b>".$_POST["selcat"]."<br />";
$mail->Host     = "smtp.gmail.com";
$mail->SMTPAuth = true;     
$mail->Port = 587;
$mail->Username = "gmail_email_adresi";  
$mail->Password = "gmail_sifre"; 
$mail->SMTPDebug  =0; 
$mail->IsSMTP();
$mail->IsHTML(true);
$mail->LE      = "\r\n";
$mail->CharSet = "UTF-8";
$mail->From    = "gmail_email_adresi";
$mail->FromName= "$ad";

  
  $mail->AddAddress("gonderilecek_email_adresi");
  $mail->Subject = "Web Bloklama İzin İsteği";
  $mail->Body    = $body;
  if($mail->Send()){
    echo("Bilgileriniz yetkili kişilere gönderilmiştir.");
  }else{
    echo("Problem var. Lütfen daha sonra deneyiniz.");
  }
?>
