Page 11: Connecting The Cable/Dsl Router To Your Network
Connecting the Cable/DSL Router to Your Network Overview Unlike a hub or a switch, the Cable/DSL Router’s setup consists of more than simply plugging hardware together. Since the Router acts as a DHCP server, you will have to set some values for the Router and also configure your net- worked PCs to accept the IP addresses that the Router assigns them. -
Page 12: Connecting Your Hardware Together & Booting Up
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. -
Page 13: Uplinking: Connecting More Devices To Your Router
This leaves you with new, open ports on the hub or switch, to which you can add more PCs and/or network devices. See your nearest Linksys retailer or visit www.linksys.com for complete product lines of 10/100 Mbps hubs and switches. -

If DMZ Hosting is used, does the exposed user/PC share the public IP address with the Router? No. Does the Router pass PPTP packets or actively route PPTP sessions? The Router allows PPTP packets to pass through. Is the Router cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the Router. - Page 34 Bridge - A device that interconnects different networks together. Broadband - A data-transmission scheme in which multiple signals share the bandwidth of a medium. This allows the transmission of voice, data and video signals over a single medium. Cable television uses broadband techniques to deliver dozens of channels over one cable.
- Page 35 DHCP supports static addresses for computers containing Web servers that need a permanent IP address. DMZ - (Demilitarized Zone) allows one IP address (or computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP address if you want to use DMZ Hosting.
- Page 36 Full Duplex - The ability of a device or line to transmit data simultaneously in both directions. Gateway – A device that interconnects networks with different, incompatible communications protocols. Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time.
- Page 37 NetBEUI (NetBIOS Extended User Interface) - The transport layer for NetBIOS. NetBIOS and NetBEUI were originally part of a single protocol suite that was later separated. NetBIOS sessions can be transported over NetBEUI, TCP/IP and SPX/IPX protocols. NetBIOS - The native networking protocol in DOS and Windows networks. Although originally combined with its transport layer protocol (NetBEUI), NetBIOS today provides a programming interface for applications at the ses- sion layer (layer 5).

PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL providers for connecting personal computers to a broadband modem for Internet access.
- Page 39 TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your comput- er is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.
