check box). The FSG1100HN's
purpose is to allow a private Local Area Network (LAN) to be securely connected to
the Internet. The FSG1100HN can be used to prevent theft, destruction and
modification of data, as well as log events, which may be important to the security
of your network.
The FSG1100HN is installed between the LAN and a broadband modem connecting
