7.7 The Portal Screen

Click Advanced > Portal to open this screen. This is where you can configure your captive
portal web page parameters.
The captive portal mechanism restricts wireless client Internet access by redirecting initial
web access requests to the captive portal web page. Once the page appears, the wireless client
must login to authenticate his device, after which he may surf the Internet or browse other
local network connections (depending on your network permissions, of course.)
There are two types of captive portal web pages:
• SSL-based Secured Logging: With this type of captive portal, a wireless client is initially
authenticated before being allowed network access. A user enters his username and
password over an SSL connection. The NXC-8160 then authenticates him on a connected
RADIUS server. Secured Logging is used primarily for networks that require
authentication-based access such as hotels, coffee shops, guest access, and so on.
