Some ISPs do not give their clients a static IP. Therefore your IP might change from time to time. It’s not a problem if you use our software as it has an “Automatic IP update” feature. This might become very annoying when you have to validate your IP manually each time you want to use Smart DNS in case of a manual connection. Though we have found a solution even if you use manual setup and you have a DD-WRT router.
To validate the IP automatically, follow these instructions step-by-step:
Important! Replace “[VALIDATE_IP_LINK]” with your Validate IP Link. To find it, sign in to the client area on our website, go to “Packages”, click on your package and find the box “Validate IP Link”. Replace [x_min] with the periodicity of the validate in minutes. For example: 5 – for 5 minutes; 120 – for 2 hours
An example how your rule must look like:
*/5 * * * * root wget http://smartdns.cactusvpn.com/index.php?smartkey=4894fcaa1fe9fcff5gwt853fd11f
This will validate your IP every 5 minutes.
