Third-Party Captive Portal Solutions

The last entry in the filter should be a rule that drops all other traffic, so that

traffic other than the passthrough will not be allowed to transverse the Captive

Portal without authentication.

Captive Portal With N+1

Captive Portal changes are propagated in an Nplus1 environment as follows. When a

slave takes over a master, it uses the master's Captive Portal pages. If changes are

made on that active slave, that change is not automatically propagated to the

master.

Troubleshooting Captive Portal

 The same subnet should not be entered for both CaptivePortal1 and

CaptivePortal2. If you do this, only the CaptivePortal1 configured splash page will

be displayed.

 Custom pages have to imported properly before making use of this feature. See

Optionally Customize and Use Your Own HTML Pages.

 To check if the pages and images have been properly imported into the controller

use the command show web custom-area

 To check if the imported page is coming up properly use the CLI

https://<controller ip>/vpn/<page Name>

 To ensure that Captive Portal authentication is taking place, look at the

access-accept message from the Radius server during Captive Portal

authentication.

 Even when using custom CP pages, four default HTML files are used; only two are

actually customized. The only way to change this is to alter the four default files

which are used for both CP1 and CP2.

 The AP List is limited by space. If you exceed the space limit, the CLI command

fails and the list of APs that you entered are lost.

Third-Party Captive Portal Solutions

Instead of using the Meru Captive Portal solution, you can use a third-party solution;

you cannot use both. Companies such as Bradford, Avenda, and CloudPath all provide

Captive Portal solutions that work with System Director 4.1 and later. There are two

places that you need to indicate a third-party captive portal solution, in the corre-

sponding Security Profile and in the Captive Portal configuration.
