Validate your IP automatically using a DD-WRT router

Some of our users need to validate their IP address often as their ISP gives them a dynamic IP. When using our software you don’t have to worry about it as the software has the “Dynamic IP updater” feature. But in case you use other OS/devices we offer you the following solution.

You can add a cron job on your DD-WRT router to validate your IP address automatically every 5-10 minutes.

To do that, follow these instructions step-by-step:

  1. Open your DD-WRT router settings.
  2. Go to Administration -> Management, and scroll down till you see the section “CRON”.
  3. Add the following rule:

    */5 * * * * root wget [VALIDATE_IP_LINK]

    Important! Replace “[VALIDATE_IP_LINK]” with your Validate IP Link. To find it, sign in to your account on our website, go to “Packages”, click on your package and find the box “Validate IP Link”.

Rules examples
