How to Set up the DMZ in your router for the Phone Power Device

To Configure your device to function with the Grandstream connected to it, please follow these instructions.

For the first step in this process, we will need to find out the current IP address being assigned to your Grandstream by your router. Please refer to How to receive the current WAN IP Address on a Grandstream for more information.

Next, connect your computer directly to your router, open up a web browser and log into the router.

Once you are logged in:

• Go to the DMZ section of the router.

This is usually in the Firewall settings or an Advanced section of the router.

Once you are on the DMZ page, set up the DMZ as follows:

• Enable the DMZ.
• Set the DMZ to the IP address that you received from the Grandstream in the first step of this process.
• Save the settings once that is complete.

You will need to reboot the Grandstream device for this to take effect. Simply remove the power cord from the back of the Grandstream, wait 20 seconds, and put it back in. After 3-5 minutes the Grandstream should be registered and able to make and receive calls.

If you are unable to place a call after 15 minutes, please contact our support department for additional assistance.
