The content security feature on GWN700x routers allows users to filter (block) content based on DNS, APP or URL. DNS and URL filtering uses keywords and wildcard * (which can represent any string) while APP filtering works by selecting APPs from a list organized in categories.
To filter (block) content please follow the steps below:
Disable Hardware Acceleration
Navigate to Web UI → Network Settings → Network Acceleration, then toggle OFF “Hardware Acceleration“.
Enable Traffic Identification
Navigate to Web UI → Traffic Management → Basic Settings, then toggle ON “Traffic Identification“.
Add a Content Security Filter
Navigate to Web UI → Firewall → Content Security, click on DNS Filtering, APP Filtering or URL Filtering tab, then click on “Add” button to add a new filter.
Example: DNS Filtering for media streaming, click on “minus” or “plus” icons to add or remove an entry, refer to the figure below:
Enter keywords and wildcard characters * (which can represent any string). Wildcard * can only be added before or after the input keyword, for example: *.imag, news*, *news*. Please enter a valid domain name, not an IP address.

Add a Traffic Rule
- If the client’s devices are using the default DNS Server of the GWN700x router, in this case, the DNS traffic is handled by “Inbound Rules“.

Navigate to Web UI → Firewall → Traffic rules, click on Inbound Rules tab, then click on “Add” icon to add a new Inbound rule, scroll down and enable “Content Security” then select the previously created filters from the drop-down list under DNS Filtering, APP Filtering and URL Filtering accordingly, refer to the figure below:
Navigate to Web UI → Firewall → Traffic rules, click on Forwarding Rules tab, then click on “Add” icon to add a new forwarding rule, scroll down and enable “Content Security” then select the previously created filters from the drop-down list under DNS Filtering, APP Filtering and URL Filtering accordingly, refer to the figure below:
