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 WEP key on the Motorola SBG1000 Wireless Cable Modem Gateway and wireless LAN clients (stations).

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

For information about configuring a WEP key, see “Configuring Basic Wireless LAN Security” on page 73.

Virtual Private Networks

The SBG1000 allows multiple tunnel VPN pass-throughoperation to securely connect remote computers over the Internet through the SBG1000. The SBG1000:

•Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP)

•Is fully interoperable with any IPSec client or gateway and ANX certified IPSec stacks
