4.Check the protocol you will be using, TCP and/or UDP.

5.Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

6.Check the Enable option for the port services you want to use. Consider the example below:

When you have completed the configuration, click the Save Settings button.

9.I can’t get the Internet game, server, or application to work.

If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding settings. If the port number that the data enters from does not have port forwarding, then the Router will send the data to whichever PC or network device you set for DMZ hosting.)

Follow these steps to set DMZ hosting:

1.Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Applications & Gaming => Port Forwarding tab.

2.Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time.

3.Go to the Applications & Gaming => DMZ tab.

4.Select Enable next to DMZ. In the DMZ Host IP Address field, enter the IP address of the computer you want exposed to the Internet. This will bypass the NAT technology for that computer. Please refer to “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

Once completed with the configuration, click the Apply button.

10.I forgot my password, or the password prompt always appears when I am saving settings to the Router.

Reset the Router to factory default by pressing the Reset button for 10 seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps:

WRT54G specifications

The Cisco Systems WRT54G is a cornerstone of home and small office networking, renowned for its robust features and reliability since its release in 2002. Widely acknowledged as one of the first consumer-grade routers to combine wireless and wired networking capabilities, the WRT54G has earned a legacy as a hallmark of simplicity and performance.

At the heart of its functionality is the 802.11g wireless standard, which allows for wireless connections at speeds of up to 54 Mbps. This technology ensures a reliable connection over significant distances, making it suitable for various home and office environments. The WRT54G operates on the 2.4 GHz frequency band, which provides compatibility with many devices but can be susceptible to interference from other electronic devices.

One of the standout features of the WRT54G is its user-friendly web interface, allowing even non-technical users to easily configure their network settings. This feature promotes security by enabling users to modify their network name, set up encryption protocols like WEP or WPA, and create a guest network for visitors. The router also incorporates a built-in firewall and supports Network Address Translation (NAT), adding an additional layer of security to users’ private networks.

The WRT54G boasts four Ethernet ports for wired connections, accommodating multiple devices simultaneously. This feature is particularly beneficial for users with desktop computers, gaming consoles, or network-attached storage devices requiring stable, high-speed connections. The ability to connect devices through Ethernet ensures that users can enjoy the benefits of a reliable and fast network, especially in environments where wireless connectivity may be limited.

Another distinguishing characteristic of the WRT54G is its open-source firmware capability, which has led to a devoted community of enthusiasts who have developed alternative firmware for greater customization and advanced features. This flexibility not only enhances the router's lifespan but also caters to users who require specific functionalities, such as advanced Quality of Service (QoS) settings or more extensive parental controls.

In conclusion, the Cisco Systems WRT54G remains a significant player in the realm of consumer networking due to its innovative features, ease of use, and adaptability. While newer models have since emerged, the WRT54G's enduring reputation speaks to its reliability and solid performance, making it a preferred choice for many users seeking to establish a dependable network.
