2.6.5 Whitelist

The Whitelist is a list of up to 20 WLAN client MAC (Media Access Control)

addresses that are allowed to access the Ericsson W20. A MAC address is

the unique hardware number of a device. It has the form of

xx:xx:xx:xx:xx:xx, where x is either a letter A – F or a number.

To find out about the MAC address of a PC using Microsoft Windows, open

a command prompt and type ipconfig

/all. A list of system properties

is displayed. The MAC address is found on the Physical

Address row.

To add a client to the whitelist, type the MAC address of the client in the

Whitelist field on the Wireless LAN page and click Add .

Click Apply to save the settings.

2.7 DHCP Server

The Ericsson W20 incorporates a DHCP (Dynamic Host Configuration

Protocol) server that assigns dynamic IP addresses to local clients. The IP

addresses are collected from a predefined range of available addresses.

The default address range is suitable for most local networks.

The DHCP server uses the concept of a "lease”, that is the amount of time

that a given IP address will be valid for a specific device. If the lease time

expires and the device is still connected, the lease is automatically

renewed.
