About the BM2022s Security Features
The BM2022 security features are designed to protect against Denial of Service attacks when
activated as well as block access to and from specific URLs and MAC addresses. Its purpose is to
allow a private Local Area Network (LAN) to be securely connected to the Internet. The BM2022 can
be used to prevent theft, destruction and modification of data.
The BM2022 is installed between the LAN and a WiMAX base station connecting to the Internet.
This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The BM2022 has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network
of computers, which needs security from the outside world. These computers will have access to
Internet services such as e-mail, FTP and the World Wide Web. However, inbound access is not
allowed (by default) unless the remote host is authorized to use a specific service.
