ADSL Gateway with 4-Port Switch Chapter 1: Introduction Welcome Thank you for choosing the ADSL Gateway with 4-Port Switch. This Gateway will allow your computers to share a high-speed Internet connection with its built-in modem, as well as share resources, including files and printers, through its built-in Switch. Because the modem, router, and switch are all built-in, creating a network is easier than ever. Put simply, networks are useful tools for sharing computer resources.
ADSL Gateway with 4-Port Switch What’s in this Guide? This user guide covers the steps for setting up and using the ADSL Gateway. • Chapter 1: Introduction This chapter describes the ADSL Gateway and its documentation. • Chapter 2: Planning your Network This chapter describes the basics of networking. • Chapter 3: Getting to Know the ADSL Gateway This chapter describes the physical features of the Gateway.
ADSL Gateway with 4-Port Switch • Appendix G: Specifications This appendix provides the technical specifications for the Gateway. • Appendix H: Warranty Information This appendix supplies the warranty information for the Gateway. • Appendix I: Regulatory Information This appendix supplies the regulatory information regarding the Gateway. • Appendix J: Contact Information This appendix provides contact information for a variety of Linksys resources, including Technical Support.
ADSL Gateway with 4-Port Switch Chapter 2: Planning your Network The Gateway’s Functions A Gateway is a network device that connects two networks together. In this instance, the Gateway connects your Local Area Network (LAN), or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks. The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers.
ADSL Gateway with 4-Port Switch Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Gateway. You can get that information from your ISP. Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.
ADSL Gateway with 4-Port Switch telecommuters, and/or professionals on the road (travelers can connect to a VPN Gateway using any computer with VPN client software that supports IPSec, such as SSH Sentinel.) There are two basic ways to create a VPN connection: • VPN Gateway to VPN Gateway • Computer (using VPN client software that supports IPSec) to VPN Gateway The VPN Gateway creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure.
ADSL Gateway with 4-Port Switch data inside of a local network. But what do you do once information is sent outside of your local network, when emails are sent to their destination, or when you have to connect to your company's network when you are out on the road? How is your data protected? That is when a VPN can help. VPNs secure data moving outside of your network as if it were still within that network. When data is sent out across the Internet from your computer, it is always open to attacks.
ADSL Gateway with 4-Port Switch Chapter 3: Getting to Know the ADSL Gateway The Back Panel Figure 3-1: Back Panel The Gateway’s ports, where a network cable and DSL cable are connected, are located on the back panel. The Gateway’s buttons are also located on the back panel. LINE The LINE port connects to the ADSL line. Ethernet (1-4) The Ethernet ports connect to your computer and other network devices. Power The Power port is where you will connect the power adapter.

The Power LED lights up when the Gateway is powered on. Ethernet (1-4) Green. The Ethernet LEDs serve two purposes. If an LED is continuously lit, the Gateway is successfully connected to a device through that LAN port. If an LED is blinking, it is an indication of any network activity on that port. DSL Green.
ADSL Gateway with 4-Port Switch Chapter 4: Connecting the ADSL Gateway Overview The Gateway’s setup consists of more than simply plugging hardware together. You will have to configure your hardware: the physical aspect of computers, networked computers to accept the IP addresses that the Gateway assigns them (if applicable), and you will also telecommunications, and other information technology devices have to configure the Gateway with setting(s) provided by your Internet Service Provider (ISP).
ADSL Gateway with 4-Port Switch 5. Connect the power adapter to the Gateway’s Power port, and then plug the power adapter into a power outlet. Turn the On/Off switch to On. • The Power LED on the front panel will light up green as soon as the power adapter is connected properly and the switch is turned on. The Power LED will flash for a few seconds, then it will light up steady when the self-test is complete. If the LED flashes for one minute or longer, see “Appendix A: Troubleshooting.” 6.
