About the WiMAX Device’s Security Features
The WiMAX Device 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 WiMAX Device can be used to prevent
theft, destruction and modification of data.
The WiMAX Device 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 WiMAX Device 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.
