How to block Internet access of a network client
Suppose that you want to immediately block Internet access to a particular client on your home network. There are many ways to do this in Netcraze routers.
We will review the fastest way through the router's web interface. Open the Connection Policies page and go to the Policy Binding tab. In the Default policy, locate the desired client in the Clients list and drag it from the right column to the No Internet access policy in the left column.
The setup is complete. Internet access will be blocked only for the clients to which this policy is assigned.
Now, let's look at other methods of a similar configuration.
In the web interface on the Client Lists page, you can choose the necessary device, in its settings in the Connection policy field, set it to No Internet access and press the Save button.
It's also easy to block Internet access with the mobile app Netcraze. For more information, see the article Blocking Internet access using the Netcraze app.
Also, in the web interface, on the My Networks and Wi-Fi page, you can disable Internet access for all unregistered clients which currently exist or may appear on your home network. To do this, select No Internet access in the Connection policy field in the Internet Traffic Handling Rules section. With this setting, only registered devices can be configured to access the Internet. Individual settings for registered clients override the segment defaults.
Important
Only the transit traffic going from a network client to an Internet host is blocked. The proxied DNS proxy traffic is not blocked, but all metadata is removed from the proxied DNS requests, preventing any response from the Internet from reaching the blocked client.
In addition to the above methods, you can also manage your Internet access using the scheduling mechanism. You can find additional information in the articles:
