What is Deep Packet Inspection (DPI) (Lite)?

Deep Packet Inspection (DPI) (Lite) is a security feature that allows Organization Admins to block specific ports and protocols from being accessed while connected to your organization’s virtual private gateways.

For example, you can use DPI to block specific messaging services like Snapchat or Viber and peer-to-peer file-sharing apps like Stealthnet or Thunder.

How to enable DPI (Lite)?

  1. Go to Control PanelNetworkServers or Gateways. Choose the dedicated server, click Configure next to it, and select Deep Packet Inspection (Lite) from the dropdown menu;


  1. In the request form, select which ports and protocols you want to inspect and block. With NordLayer, you can choose from up to 250 ports and protocols (find the list below);

  2. Once you’re done, click on Request Deep Packet Inspection. Please allow up to 24 hours for the feature to be enabled. You will get an email with the confirmation once it’s ready.
