Instant Broadband™ Series ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready Chapter 1: Introduction The Linksys ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready Thank you for choosing the Instant Broadband™ ADSL Gateway with Modem / Router / 4Port Switch / Wireless-Ready. This Gateway allows you to set up a network with your PCs and share your Internet connection.
Instant Broadband™ Series ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready Think of the Gateway as a network device with two sides: the first side is made up of your private Local Area Network (LAN) of PCs. The other, public side is the Internet, or the Wide Area Network (WAN), outside of your home or office. The Gateway’s firewall (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your LAN, or network, remains private.
Instant Broadband™ Series Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as PCs and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the PC or device. After a certain time period, they expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.
