About the MAX208M2W Series ’ s Security Features
The MAX208M2W Series 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 MAX208M2W Series can be
used to prevent theft, destruction and modification of data.
The MAX208M2W Series 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 MAX208M2W Series 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.
