Parameter
Description
URL
Enter the URL for the external captive portal
server.
Port
Enter the port number.
Use https (Available only if
RADIUS Authentication
is selected)
Select Enabled to enforce clients to use HTTPS
to communicate with the captive portal server.
Captive Portal failure
Allows you to configure Internet access for the
guest clients when the external captive portal
server is not available. Select Deny Internet to
prevent clients from using the network, or Allow
Internet to allow the guest clients to access
Internet when the external captive portal server
is not available.
Automatic URL Whitelisting
Select Enabled to enable the automatic white-
listing of URLs. On selecting the check box for
the external captive portal authentication, the
URLs that are allowed for the unauthenticated
users to access are automatically whitelisted.
The automatic URL whitelisting is disabled by
default.
Auth Text (Available only if
Authentication Text is
selected)
If the External Authentication splash page is
selected, specify the authentication text to be
returned by the external server after successful
authentication.
Server Offload
Select Enabled to enable server offload. The
server offload feature ensures that the non-
browser client applications are not unnecessari-
ly redirected to the external portal server and
thereby reducing the load on the external cap-
tive portal server. The Server Offload option is
Disabled by default.
Prevent frame overlay
When the Prevent frame overlay option is ena-
bled, a frame can display a page only if it is in
the same domain as the main page. This option
is Enabled by default and can be used to pre-
vent the overlay of frames.
Switch IP
Sends the IP address of the VC in the redirec-
tion URL when external captive portal servers
are used. This option is disabled by default.
Redirect URL
Specify a redirect URL if you want to redirect
the users to another URL.
