CONFIGURING THE CONNECTION TO THE ACCESS CONTROLLER
The LPS-20x uses the services of an access controller to manage access to the public access network.
Unlike a traditional bridge which automatically forwards all traffic between ports, the LPS-20x features an intelligent
bridge which can apply filters to maintain the security of the network. When the security filters are active, the
LPS-20x only allows traffic to flow between itself and the access controller. This prevents wireless customers from
accessing resources on the backbone LAN that interconnects the LPS-20x and the access controller.
SECURITY FILTERS
To configure the connection to the access controller and enable the intelligent bridge, do the following:
1. On the main menu, click Security and then click Access controller. The Access controller configuration
page opens.
2. By default, the LPS-20x uses the default gateway as the access controller.
• If you are using static IP addressing, make sure that you set the default gateway on the LPS-20x to be the
access controller.
• If you are using a DHCP server on your network, make sure that it is configured to return the IP address of
the access controller as the default gateway. (The access controller is configured to do this by default.)
Alternately, you can specify the MAC address of the access controller.
3. Clear the security filters check box if you are connecting to a wired LAN (refer to
Connecting to a wired LAN on page 92).
4. Click Save.
ACCESS CONTROLLER SHARED SECRET
To maintain the security of network logins, the ADC access controller will only accept location-aware information
from a LPS-20x that has a matching shared secret to its own.
