Scenario 2a: Hotspot with Internet access (RADIUS)

This installation creates a public access network using a RADIUS server to handle
customer authentication.

How it works

In this scenario, a single CN3000 is installed to provide a wireless network and access
to the Internet. A network operating center (either local or remote) provides the RADIUS
server for authentication.
A local area network is connected to the CN3000's LAN port to support wired
customers.
There are two ways to deploy this scenario.
Topology 1
In this version, the NOC is located on the Internet. The CN3000 connects to the VPN
server at the NOC using its PPTP client. This provides a secure link through which data
can be transferred.
The firewall and NAT are also enabled to safeguard the Internet connection.
