ADSL2 Gateway with 4-Port Switch Chapter 1: Introduction Welcome The Linksys ADSL2 Gateway with 4-Port Switch is the all-in-one solution for Internet connectivity in your home. The ADSL Modem function gives you a blazing fast connection to the Internet, far faster than a dial-up, and without tying up your phone line. Connect your computers to the Gateway via the built-in 4-port 10/100 Ethernet Switch to jump start your home network.
ADSL2 Gateway with 4-Port Switch What’s in this Guide? This user guide covers the steps for setting up and using the ADSL2 Gateway with 4-Port Switch. • Chapter 1: Introduction This chapter describes the ADSL2 Gateway with 4-Port Switch ADSL2 Gateway with 4-Port Switch applications and this User Guide. • Chapter 2: Planning Your Network This chapter describes the basics of networking.
ADSL2 Gateway with 4-Port Switch • Appendix G: Warranty Information This appendix supplies the warranty information for the Gateway. • Appendix H: Regulatory Information This appendix supplies the regulatory information regarding the Gateway. • Appendix I: Contact Information This appendix provides contact information for a variety of Linksys resources, including Technical Support.
ADSL2 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.
ADSL2 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.
ADSL2 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.
ADSL2 Gateway with 4-Port Switch protect 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.
