Configuring Wireless Client Ip Address Assignment - ADTRAN BlueSecure Controller Setup And Administration Manual

• Optionally define one or more virtual LANs (VLANs) on the managed side
• Optionally define a managed remote subnet for those network configurations where
the wireless network is not directly connected to the BSC managed interface (on some
IP subnet) but instead is accessible only across a routed network
• Optionally configure a managed virtual interface for special networking topologies
or applications that cannot communicate directly with the BSC managed physical
interface, VLAN, or managed remote subnet

Configuring Wireless Client IP Address Assignment

Configuring the BSC managed interface requires that you define how the BSC assigns IP
addresses to wireless clients on the managed side of the network. You can opt to:
• Configure the BSC to behave as a DHCP relay agent whereby the BSC relays all
client DHCP requests to a DHCP server running on the protected side of the network
and returns the IP address, DNS, and other options to the client from the server.
• If you are not running a DHCP server, you can either set the BSC to dynamically
assign addresses to wireless clients via its resident DHCP server, or you can assign
fixed IP addresses to wireless clients, or you can do both.
It is possible to configure client addressing on the managed side of the network for
both dynamic and fixed assignment. However, if both IP address assignment modes
are configured, the fixed IP address always takes precedence.
Procedures to configure these wireless client IP address assignment options are provided
in the sections that follow.
Configuring a DHCP Relay Agent
To configure the BSC to use a DHCP relay agent to pass DHCP requests to an external
DHCP server on the protected side of the network and assign IP addresses to wireless
clients on the managed side of the network:

that you do not restart the BSC until you have completely finished configuring the BSC for
use in your network.

DHCP servers Enter the IP address or fully qualified domain name of each DHCP server in your network,
separated by commas.
Note: The entered DHCP servers should reside on the protected side of your network.
To broadcast a DHCP request to any DHCP server, leave the DHCP servers field blank.
The following figure shows an example of the Edit Managed interface (eth1) page with
the DHCP relay options configured.

It is possible to configure client addressing on the managed side of the network
for both dynamic and fixed assignment. However, if both assignment modes are
configured, the wireless client's fixed IP address always takes precedence.
