authentication device. The access point issues an IP address to the user using a DHCP Server,
authenticates the user and grants the user to access the Internet.
If a tourist visits a public hotspot and wants to browse a Web page, they boot their laptop and
associate with a local Wi-Fi network by entering a valid SSID. They start a browser, and the hotspot’s
access controller forces the un-authenticated user to a Welcome page (from the hotspot operator)
that allows the user to login with a username and password. In order to send a redirected page (a
login page), a TCP termination exists locally on the access point. Once the login page displays, the
user enters their credentials. The access point connects to the RADIUS server and determines the
identity of the connected wireless user. Thus, allowing the user to access the Internet once
successfully authenticated.
For detailed information on configuring the access point for Hotspot support, see Configuring WLAN
Hotspot Support on page 5-45.
1.2.30 Routing Information Protocol (RIP)
RIP is an interior gateway protocol that specifies how routers exchange routing-table information.
The parent Router screen also allows the administrator to select the type of RIP and the type of RIP
authentication used.
For detailed information on configuring RIP functionality as part of the access point’s Router
functionality, see Setting the RIP Configuration on page 5-71.
1.2.31 Manual Date and Time Settings
As an alternative to defining a NTP server to provide access point system time, the access point can
now have its date and time set manually. A new Manual Date/Time Setting screen can be used to set
the time using a Year-Month-Day HH:MM:SS format.
For detailed information on manually setting the access point’s system time, see Configuring Network
Time Protocol (NTP) on page 4-41.
1.2.32 Dynamic DNS
The access point supports the Dynamic DNS service. Dynamic DNS (or DynDNS) is a feature offered
by www.dyndns.com allowing the mapping of domain names to dynamically assigned IP addresses.
When the dynamically assigned IP address of a client changes, the new IP address is sent to the
DynDNS service and traffic for the specified domain(s) is routed to the new IP address. For
information on configuring Dynamic DNS, see Configuring Dynamic DNS on page 5-25.
