DMZ

A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG900 LAN and the Internet. A DMZ prevents direct access by outside users to private data.

For example, you can set up a Web server on a DMZ computer to enable outside users to access your website without exposing confidential data on your network.

A DMZ can also be useful to play interactive games that may have a problem running through a firewall. You can leave a computer used for gaming only exposed to the Internet while protecting the rest of your network. For more information, see “Gaming Configuration Guidelines”.

Port Triggering

When you run an application that accesses the Internet, it typically initiates communications with a computer on the Internet. For some applications, especially gaming, the computer on the Internet also initiates communications with your computer. Because NAT does not normally allow these incoming connections:

•

•

The SBG900 has preconfigured port triggers for common applications.

If needed, you can configure additional port triggers on the Gateway > PORT TRIGGERS — custom Page.

Wireless Security

Because WLAN data is transmitted using radio signals, it may be possible for an unauthorized person to access your WLAN unless you prevent them from doing so. To prevent unauthorized eavesdropping of data transmitted over your LAN, you must enable wireless security. The default SBG900 settings neither provide security for transmitted data nor protect network data from unauthorized intrusions.

The SBG900 provides the following wireless security measures, which are described in “Setting Up Your Wireless LAN”:

•

•

To prevent unauthorized eavesdropping, you must encrypt data transmitted over the wireless interface using one of:

—If all of your wireless clients support Wi-Fi®Protected Access (WPA) encryption, we recommend using WPA (see “Configuring WPA on the SBG900” and “Configuring a Wireless Client for WPA”).

—Otherwise, configure a Wired Equivalency Privacy (WEP) key on the SBG900 and each WLAN client (see “Configuring WEP on the SBG900” and “Configuring a Wireless Client for WEP”).

To protect LAN data from unauthorized intrusions, you can restrict WLAN access to computers having one or both of:

—Known MAC addresses (see “Configuring a MAC Access Control List on the SBG900”)

—The same unique network name (ESSID) as the SBG900 (see “Configuring the Wireless Network Name on the SBG900” and “Configuring a Wireless Client with the Network Name (ESSID)”)

Restricting access to computers having the same network name is also called “disabling ESSID broadcasting” or “enabling closed network operation.”

This enables users to enjoy seamless streaming, online gaming, and quick downloads without interruptions. The device is also backward compatible with earlier DOCSIS standards, ensuring that it remains functional even with older cable networks.

Another notable aspect of the Motorola SBG900 is its built-in Wi-Fi capabilities. The device supports the IEEE 802.11b/g wireless standards, allowing for wireless speeds of up to 54 Mbps. This makes it easy to connect multiple devices throughout the home or office, including laptops, smartphones, tablets, and smart TVs. The wireless range is enhanced by its internal antennas, offering reliable connectivity in various locations within the premises.

Security is a critical consideration for any networking device, and the SBG900 addresses this need with multiple features. It comes equipped with Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalent Privacy (WEP) encryption protocols, ensuring that both wired and wireless connections remain secure from unauthorized access. Furthermore, the device supports a built-in firewall, adding an extra layer of protection by controlling incoming and outgoing traffic.

The Motorola SBG900 also boasts a user-friendly web-based management interface, providing easy access to configuration settings and status monitoring. Users can effortlessly manage their network, set up parental controls, prioritize devices using Quality of Service (QoS), and perform firmware updates.

In summary, the Motorola SBG900 stands out as a reliable solution for users seeking a powerful cable modem with integrated Wi-Fi capabilities. With high-speed internet access, robust security features, and ease of management, it serves as an ideal choice for anyone looking to enhance their connectivity experience.
