Creating a captive portal with voucher authentication

In this recipe, we will create a captive portal with authentication through pfSense's voucher system. Vouchers are an ideal form of authentication in scenarios where you want to provide access to one of your networks on a temporary basis. Setting up access via vouchers involves generating a series of voucher codes that are then issued to users. These vouchers are good for a fixed period of time (you can define this period). You can also track network usage by keeping track of which voucher codes are given to certain users.

How to do it...

1. Navigate to Services | Captive Portal.
2. Click on the Add button.
3. Enter a name into the Zone name edit box and a brief description...
