Network Setup
The configuration example in this document uses the setup displayed in this diagram. The LAP is registered to
the WLC. The WLC is connected to the Layer 2 switch. The router that connects the users to the WAN also
connects to the Layer 2 switch. You need to create two WLANs, one for the guest users and the other for the
internal LAN users. You also need a DHCP server to provide IP addresses for the guest and internal wireless
clients. The guest users use web authentication in order to access the network. The internal users use EAP
authentication. The 2811 router also acts as the DHCP server for the wireless clients.

Note: This document assumes that the WLC is configured with the basic parameters and the LAP is registered
to the WLC. Refer to Lightweight AP (LAP) Registration to a Wireless LAN Controller (WLC) for
information on how to configure the basic parameters on a WLC and how to register the LAP to WLC.

When configured as a DHCP server, some of the firewalls do not support DHCP requests from a relay agent.
The WLC is a relay agent for the client. The firewall configured as a DHCP server ignores these requests.
Clients must be directly connected to the firewall and cannot send requests through another relay agent or
router. The firewall can work as a simple DHCP server for internal hosts that are directly connected to it. This
