Captive Portal is a safe and configurable network authentication method. It allows you to protect yourself against improper use of network access and excessive network traffic due to the possibility of imposing bandwidth restrictions.The correct configuration of Captive Portal in the NACVIEW system will result in the users being redirected to the page where they will be asked to enter data for authentication. After the successful authentication, they will gain access to the desired URL and other network resources, in accordance with established access policies.
The instruction below applies to the external configuration of the Captive Portal service (embedded in network devices). If you want to learn how to configure the Captive Portal of the NACVIEW system, open the Captive Portal (NACVIEW) document.
1. From the main menu select Access Policies (Configuration section).
2. Click the Add Rule button.
3. In the form that appears, enter the following data:
| Form field | Value |
