Broadband Router Chapter 2: Networking Basics An Introduction to LANs A Router is a network device that connects two networks together. The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these two networks. The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs. This is how your LAN remains private.
Broadband Router A DHCP server can either be a designated PC on the network or another network device, such as the Router. By default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP). The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet.

D.
Broadband Router 4. I am not able to access the Router’s Web-based Utility Setup page. A. Refer to “Problem #2, I want to test my Internet connection” to verify that your computer is properly connected to the Router. B. Refer to “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS. C. Set a static IP address on your system; refer to “Problem #1: I need to set a static IP address.” D.
Broadband Router 6. I need to set up a server behind my Router. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed.
Broadband Router 7. I need to set up online game hosting or use other Internet applications. If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using.
Broadband Router 8. 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.
Broadband Router 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN. For Microsoft Internet Explorer 5.0 or higher: A. B.
Broadband Router 13. My DSL service’s PPPoE is always disconnecting. PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a period of inactivity, just like a normal phone dial-up connection to the Internet. There is a setup option to “keep alive” the connection. This may not always work, so you may need to re-establish connection periodically. A. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router.
Broadband Router • If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is working correctly. You can remove the Router to verify a direct connection. • Manually configure the TCP/IP with a DNS address provided by your ISP. • Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab.
Broadband Router I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port (8080 usually works well but is used for remote admin.
Broadband Router new features that you would like to use. Downloading a more current version of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability. Will the Router function in a Macintosh environment? Yes, but the Router’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or higher for Macintosh. I am not able to get the web configuration screen for the Router.
Broadband Router How can I check whether I have static or DHCP IP addresses? Ask your ISP to find out. How do I get mIRC to work with the Router? Under the Setup => Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC. If your questions are not addressed here, refer to the Linksys website, www.linksys.com.
