Configuring Captive Portal
You may want to direct users to a web portal before they can access the Internet
through the security appliance. To achieve this goal, you can enable Captive Portal
on a wireless network, a VLAN, or a DMZ.
When a user in a Captive Portal user group attempts to access the Internet via a
web browser, a portal page appears. You can require a log in or the entry of
payment information, for example, and you can set up the portal page to display
information, usage guidelines, warning messages, and so on. After successfully
logging in, paying, or acknowledging your messages, the user can use other
applications on the PC to communicate with the network.
In addition to the portal options mentioned above, additional options make it easy
to adapt the Captive Portal feature to your needs:
• You can specify certain domains that users can access without going
through the portal.
• The portal page can be stored locally on the ISA500 device or on an
external web server that you specify.
