What is DMZ?

Demilitarized Zone:

In computer networks, a DMZ (demilitarized zone) is a computer host or small network inserted as a neutral zone between a company´s private network and the outside public network. It prevents outside users from getting direct access to a server that has company data. (The term comes from the geographic buffer zone that was set up between North Korea and South Korea following the UN police action in the early 1950s.) A DMZ is an optional and more secure approach to a firewall and effectively acts as a proxy server as well.

In a typical DMZ configuration for a small company, a separate computer (or host in network terms) receives requests from users within the private network for access to Web sites or other companies accessible on the public network. The DMZ host then initiates sessions for these requests on the public network. However, the DMZ host is not able to initiate a session back into the private network. It can only forward packets that have already been requested.

Users of the public network outside the company can access only the DMZ host. The DMZ may typically also have the company´s Web pages so these could be served to the outside world. However, the DMZ provides access to no other company data. In the event that an outside user penetrated the DMZ hosts security, the Web pages might be corrupted but no other company information would be exposed. D-Link, a leading maker of routers, is one company that sells products designed for setting up

a DMZ.

How do I configure the DMZ Host?

The DMZ feature allows you to forward all incoming ports to one computer on the local network. The DMZ, or Demilitarized Zone, will allow the specified computer to be exposed to the Internet. DMZ is useful when a certain application or game does not work through the firewall. The computer that is configured for DMZ will be completely vulnerable on the Internet, so it is suggested that you try opening ports from the Virtual Server or Firewall settings before using DMZ.

Step 1 Find the IP address of the computer you want to use as the DMZ host.

To find out how to locate the IP Address of the computer in Windows XP/2000/ME/9x or Macintosh operating systems please refer to Step 4 of the first question in this section (Frequently Asked Questions).

DI-624 specifications

The D-Link DI-624 is a wireless router that has gained recognition for its robust performance and versatile features. Designed to cater to home and small office networks, this router provides users with high-speed wireless connectivity along with a range of functionalities that enhance networking capabilities.

One of the main features of the D-Link DI-624 is its compliance with the Wireless G standard (IEEE 802.11g). This allows for wireless transmission speeds of up to 54 Mbps, which is suitable for activities like web browsing, email, and streaming multimedia content. The DI-624 also supports backward compatibility with the older Wireless B standard, ensuring that users with older devices can connect without issues.

Security is a top priority for the D-Link DI-624, as it includes multiple features to safeguard the network. The router supports WPA (Wi-Fi Protected Access) and WEP (Wired Equivalent Privacy) encryption methods, allowing users to choose their preferred level of security for wireless communications. Additionally, the DI-624 comes equipped with a built-in firewall that helps protect against potential threats from the internet.

The DI-624 features a user-friendly web-based interface, making it easier for users to set up and manage their network settings. This interface is accessible through any web browser, allowing users to customize options like wireless network names, password settings, and parental controls. The router also includes DHCP (Dynamic Host Configuration Protocol), which simplifies IP address management for connected devices.

In terms of connectivity, the D-Link DI-624 is equipped with four 10/100 Ethernet ports, which enable users to connect wired devices for a stable internet connection. This dual capability of both wired and wireless connections offers flexibility when building a network.

Another notable characteristic of the D-Link DI-624 is its ability to support multiple SSIDs (Service Set Identifiers). This allows users to create separate networks for guests, ensuring that primary network resources remain secure and accessible only to authorized devices.

In summary, the D-Link DI-624 is a reliable and feature-packed wireless router ideal for small networks. With a combination of wireless performance, security measures, ease of management, and versatile connectivity options, it remains a solid choice for users looking to establish a robust home or small office network.
