Your Router’s firewall (NAT) protects your network of PCs with security so users on the public, Internet side cannot “see” your PCs. This is how your internal LAN, or network, remains private.

Remember that your Router’s por ts connect to two sides: your 10/100 LAN port(s) and the Internet WAN port. The LAN port(s) transmit data at 10 Mbps or 100 Mbps, whereas the broadband port, or WAN port, transmits data at 10 Mbps, because 10Mbps is currently the maximum speed for cable and DSL service.

IP Addressing: A Quick Lesson

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its “location,” or address, on the network. Since the Internet is simply one huge global network, every PC that logs on to the Internet also needs an IP address.

There are two ways of assigning an IP address to your network devices.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing insures that the device assigned it will always have that same IP address. Static IP addresses are commonly used with network devices such as server PCs or print servers.

If you use your Router to share your cable or 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 your Router.

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 networked PCs to accept the IP addresses that the Router assigns them.

You will need the following data from your Internet Service Provider (ISP) to install the Cable/DSL Router:

•Your broadband-configured PCs’ Computer Name and Workgroup Name

• Your broadband-configured PCs’fixed

Internet IP Address

• Your Subnet Mask

•Your Default Gateway

•Your Primary DNS Server IP address(es)

The installation technician from your ISP should hav e left this information with you after installing your broadband connection. If not, you can call your ISP to request the data.

Once you have the above values, you can begin the installation and setup of your EtherFast Cable/DSL Router.

LANs and WANs

Simply put, a router is a network device that connects two networks together.

In this instance, your EtherFast Cable/DSL Router connects your Local Ar ea

Network (LAN), or the group of PCs in your home or of fice, to the Wide Area Network (WAN), that is, the Internet. Your Router processes and regulates the

data that travels between these two networks.

Think of your Router as a network device with two sides: the first side is made up of your private Local Area Network (LAN) of PCs, which this User Guide sometimes calls the “internal LAN.” The other, public side is the Internet, or the Wide Area Network (WAN), outside of your home or office.

}

Only if applicable

Since your Router is a device that connects two networks, it needs two IP addresses—one for the LAN side, and one for the WAN side. In this User Guide, you’ll see references to the “WAN IP address” and the “LAN IP address.”

Since the Router has firewall security (NAT), the only IP address that can be seen from the Internet for your network is the Router’s WAN IP address.

However, even this WAN IP address for the Router can be blocked, so that your Router and network seem invisible to the Internet—see the Blocking

WAN Requests description under IP Filtering.

EtherFast®Cable/DSL Routers

Connecting Your Hardware Together and Booting Up

1. Before you begin, make sure that all of your hardware is powered off,

including your Router, PCs, hubs, switches, and the cable or DSL modem.

2. A.If you have the 4-Port Cable/DSL Router, connect one end of a network cable to one of the LAN ports (labeled 1, 2, 3, or 4) on the back of the Router, and the other end into a standard port on a network de vice, e.g., a PC, print server, hub, or switch. See the Twisted-Pair Cabling section for details on network cabling.

Repeat the above step to connect more PCs or network devices to the Router.

2. B. If you are connecting the 1-Port Router to just one PC, plug one end of a network cable into the Router’s LAN port and the other end into the PC’s network adapter port. Set the Crossover Switch to straight-through mode

(

|| ). If the straight-through mode does not light up a Link LED, see the

chart in the Getting to Know the 1-Port EtherFast Cable/DSL Router section.

If you are connecting the 1-Port Router to a hub or switch, plug one end of a network cable into the Router’s LAN port, and the other end into to a standard port on your network’s hub or switch. Set the LAN port’s Crosso v er

Switch to its straight-through ( || ) mode. Please refer to the chart in the

Getting to Know the 1-Port EtherFast Cable/DSL Router section.

If your hub or switch has no more standard ports available, connect the

Router using its LAN port to the Uplink por t on the hub or switch. Set the Crossover Switch to straight-through mode ( || ) for this set-up.

2. C. If you have the 3-Port Cable/DSL Router, connect one end of a net- work cable from the one of the Router’s LAN ports (labeled 1, 2, or 3) to a port on a PC, hub, switch, or other network device.

The 3-Port Router features one USB plug-and-play port that connects instantly to any USB-ready PC or hub. This allows you to connect to and access your Router without even installing any network cards.

A standard port is any port other than the WAN port

and the Uplink port. It’s a straight-through port.

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 on to the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

PCs and other network devices using dynamic IP addressing are assigned a ne w IP address by a DHCP server. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.

DHCP servers can either be a designated PC on the network or another netw ork device, such as the Cable/DSL Router.

By factory default, a DHCP server (LAN side) is enabled on your Router. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on your Router, see the section on DHCP in The Cable/DSL

Router’ s Web-based Utility.

Even if you assign a static IP ad dress to a PC, other PCs can still use DHCP’s dynamic IP addressing,as long as the static IP is not within DHCP range of the LAN IP Address.

If the dynamic IP addressing fails to provide a dynamic IP address for any reason, please refer to the Troubleshooting Section.

3. Connect the network cable from your cable or DSL modem to the WAN

port on your Router’s rear panel. This is the only port that will w ork for y our modem connection.

4. Connect the power adapter to the Powe r port on the rear panel of the

Router, and then plug the power adapter into a power outlet.

•The Power LED on the front panel will light up green as soon as the power

adapter is connected properly.

• The Diag LED will light up red for a few seconds when the Router goes

through its self-diagnostic test. This LED will turn off when the self-test is complete.

5. Power on the cable or DSL modem.

6. Press the Reset button on the Router’s front panel with a paper clip or a pencil. Hold the button in until the Diag LED lights up and then turns off. This will restore the Router’s factory default settings.

The Router’s hardware installation is now complete.

Continue to the next section to configure

the Router with your PCs.

Technical Checkpoint:

Did you remember to check for Link LEDs for all your connections?

If all of your Link LEDs are not lighting up, make sure that all your cables are securely plugged in, and that all of your hardware is powered on properly.

EtherFast®Cable/DSL Routers

Uplinking: Connecting More Devices to Your Router

If your Router’s LAN ports are all full and you still have PCs and/or devices to connect, connect a hub or a switch to your Router.

To do so, use the Router’s Uplinkport to connect to a standard port on a hub or switch. If you have a PC/device connected to the port right next to the Uplink port (on the 3- and 4-Port Routers), disconnect that PC/device and plug it into an open port on the new hub or switch.

Since the Uplink port shares internal wiring with the port right next to it, you can only use only one of these two ports at a time: these ports are called shared ports.

If your new hub or switch also has an Uplink por t, it too can be uplinked when you next run out of ports, and so on.

Use the Router’s Uplink port to connect to a standard port on a hub or switch. 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.
