9 MAC Filtering

9.1 Overview

This chapter shows you how to enable and configure MAC address filtering that allows your
MWR102 to permit and deny access to specific devices on your network.
Enable MAC Filtering to restrict the passage of certain types of data packets from your local
network to the Internet through the travel router. Use of such filters can be helpful in securing or
restricting your local network.
By default the firewall allows all traffic that originates from your LAN computers to go to all
networks.

9.2 What You Can Do

• Use the MAC Filtering screen to enable or disable MAC Filtering, and modify what devices are
restricted to the local network.

9.3 What You Need To Know

The MWR102's MAC Filtering feature physically separates the LAN and the WAN of selected
devices, and acts as a secure gateway to keep selected devices from having access to the WAN.
The MWR102 is installed between the LAN and a broadband modem connecting to the Internet.
This allows it to act as a gateway for all data passing between the Internet and the LAN.
The MWR102 has one Ethernet WAN port and one Ethernet LAN port, which are used to
physically separate the network into two areas. The WAN (Wide Area Network) port attaches to
the broadband (cable or DSL) modem to the Internet.
The LAN (Local Area Network) port attaches to a network of computers. These computers will
have access to Internet services such as e-mail, FTP and the World Wide Web unless their MAC
address is blocked by the MWR102.
