DMZ

A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG1000
LAN and the Internet. A DMZ prevents direct access by outside users to private data. You can use a DMZ to set up
a web server without exposing confidential data on your network. A DMZ is also useful for people playing games
that have a problem running a computer game's protocol through a firewall. DMZ provides the person playing
games a way to expose a single host directly to the Internet and thus overcome any firewall issues.

Wireless Security

To prevent unauthorized eavesdropping of data transmitted over the wireless LAN, you must enable wireless
security. The default Open authentication setting provides no security for transmitted data.
You can encrypt data transmitted over the IEEE 802.11b wireless interface by configuring a
Motorola SBG1000 Wireless Cable Modem Gateway and wireless LAN
You can also define a MAC access control list to restrict wireless LAN access to specified clients based on the
client MAC address.
If you enable closed network operation, the network name (ESSID) is not transmitted in the IEEE 802.11b beacon
frame. This provides additional network protection because only IEEE 802.11b stations that are configured with
your network name can associate with the SBG1000. Closed network operation is not part of the IEEE 802.11b
standard
