The Captive Portal function in pfSense® software allows securing a network by requiring a username and password (or only a click through), entered on a portal page.
Authentication can be performed using pfSense the pfSense built-in user management, or an external authentication server such as a RADIUS server or an LDAP server.
The best source of captive portal information can be found in the pfSense Book.
Captive Portal can be configured from Services > Captive Portal, where Zones can be created or updated.
Captive portal Zone allow for the creation of separate, independent portals that operate on one or more separate interfaces. For example, there could be a zone for Wireless and a zone for Wired. Each zone has a completely isolated set of pages, configuration, users, etc.
One zone may be used by multiple interfaces, but an interface can be bound to only one zone.
When creating a captive portal zone, several tabs are available for the captive portal setup, each described below:
Captive Portal Tab¶
General management of captive portal setup and authentication. Each option is described in detail on the page
Pass-Through MAC Tab¶
Allows managing a list of MAC addresses which are allowed to bypass the portal.
These MAC addresses will bypass the portal authentication.
Allowed IP addresses¶
Allows managing a list of IP addresses which can either:
Always connect from behind the portal (clients)
Always allow clients to an IP address (external servers)
These IP addresses will bypass the portal authentication in the direction specified.
Allows management of the files which can be used to make up the contents of the captive portal authentication/click-through page.
