Introduction

This chapter describes the features of the NETGEAR Model RT311 and RT314 Internet Access Gateway Routers and discusses planning considerations for installation.

About the Router

The Model RT311 or RT314 Internet Access Gateway Router connects your local area network (LAN) to the Interne t through a n external si ngle-use r access de vice such a s a cable mode m or DSL modem.

When personal computers (PCs) on the LAN need to communicate with locations on the Internet, the PCs send requests to the r out er. The router translates th ose requ ests so that the requests appear to originate from a single PC, rather than from a network of PCs. The router delivers the requests to the external access device for transmission to the Internet.

Key Features

The Model RT311 and RT314 Internet Access Gateway Routers are flexible, high-performance, easy-to-use routers. These routers provide a cost-effective solution for connecting your entire network to a single-user broadband line, such as a cable modem or DSL modem. With minimum setup, you can install and use the router within minutes to meet the networking requirements of your LAN.

Introduction 1-1

Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

The Model RT311 and RT314 Internet Access Gateway Routers provide the following features:

• Ethernet LAN connection at 10 megabits per second (Mbps) or 100 Mbps – Internal four port 10/100 switch (Model RT314 router) – Single 10/100 port (Model RT311 router) – Autosensing for Ethernet (10BASE-T) or Fast Ethernet (100BASE-Tx) transmissions – Half-duplex or full-duplex operation

• Ethernet connection to a wide area network (WAN) device, such as a cable modem or DSL

modem

– RJ-45 interface allowing connection to a 10BASE-T device

• Protocol Support –IP routing – Dynamic extended Network Address Translation (NAT+) with port forwarding for

operation with a single static or dynamic IP address

– Dynamic Host Configuration Protocol (DHCP) server for dynamically assigning

network configuration information to PCs on the LAN

– DHCP client for dynamically obtaining configuration information fr om the Internet

Service Provider (ISP) – DNS Proxy for simplified configuration – PPP over Ethernet (PPPoE) support

• Login capability – Automatically executes user login for RoadRunner cable modem service or PPP over

Ethernet accounts

• Easy installation and management – Configure from a web browser – Built-in Manager i nterf ace for c onfig urati on of advan ced featur es, acce ssibl e by seri al

terminal or Telnet Protocol

•Security – Network Address Translation (NAT) hides local PCs from the Internet – Powerful packet filtering capabilities – Incoming port forwarding for specific services

1-2 Introduction

• Front panel LEDs for easy monitoring of status and activity

• Flash EPROM for firmware upgrade

• Five-year warranty

• Free technical support seven days a week, twenty-four hours a day

Autosensing 10/100 Ethernet

The Model RT311 and RT314 routers connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN interface is autosensing and is capable of full-duplex operation.

TCP/IP

The Model R T 311 and RT314 ro uters sup port t he Transmission Control Protocol/Inte rnet Pr otocol (TCP/IP) and Routing Information Protocol (RIP).

For further information about TCP/IP, refer to Appendix B, “Network and Routing Basics.”

• IP Address Masquerading by Dynamic NAT+

The Model RT311 and RT314 routers allow several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, an extension of Network Address Translation (NAT), is also known as IP address masquerading and allows the use of an inexpensive single-user ISP account.

• Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the router allows incoming traffic to be forwarded to specific PCs based on the service port number of the incoming request.

• Automatic Configuration of Attached PCs by DHCP

The Model RT311 and RT314 routers dynamically assign networ k configuration information, including IP, gateway, and domain name server (DNS) addres se s, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This fe ature greatly simplifies configuration of LAN-attached PCs.

• DNS Proxy

When DHCP is enabled and no DNS addresses are specified, the router provides its own address as a DNS server to the attached PCs. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

Introduction 1-3

Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

• PPP over Ethernet (PPPoE)

PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an always-on connection by simulati ng a dial-up connection.

Security

The Model RT311 and RT314 routers are equipped with severa l features designed to maintain security, as described in this section.

• PCs Hidden by NAT

Network address translation (NAT) opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the PCs on the LAN.

• Packet Filtering

The Model RT311 and RT314 routers provide extensive packet filtering capabilities. Packets are allowed or discarded based on their source or destination addresses, service port numbers, or raw data patterns within the packet.

• Port-Address Translation

The Model RT311 and RT314 routers perform port-address tra nslation. Requests originating from outside the local network are al lo we d to re ach pa rt icu la r loc al workst ations based on the type of service requested.

Easy Installation and Management

You can install, configure, and operate the Model RT311 or RT314 Internet Access Gateway Router within minutes after connecting it to the network . T he following features simplify installation and management tasks:

• Browser-based management

Browser-based configuration allows you to easily configure your router from almost any type of personal computer , such as W indows, Macintosh, or Linux . A user-friendl y Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.

• Manager Interface

The Manager interface manages and co nfigures th e router thr ough an easily und erstood screen process. You can access this inte rface through the MANAGER port on the rear panel of the router or from across the network, using a Telnet session. The Manager Interface provides access to advanced features such as custom filters.

Connecting the Rout er

Before using your router, you need to do the following:

• Connect your local Ethernet network to the LOCAL port(s) of the router (described next).

• Connect your cable or DSL modem to the INTERNET port of the router (see page 2-7).

• Connect the power adapter (see page 2-8).

Connecting to your Local Ethernet Network

Your local network will attach to the router port or ports marked LOCAL. Because the Model RT314 router includes a four-port switch whil e the Model RT311 router has a single port for connection to your local network, the method of connection is different. Follow the procedure below for your specific mo del .

The LOCAL ports of these rou ters are capable of operation at either 10 Mbps (10BASE-T ) or 100 Mbps (100BASE-Tx), depending on the Ethe rnet interface of the attached PC, hub, or switch. For any connection which will operate at 100 Mbps, you must use a Category 5 (CAT5) rated cable, such as the white Ethernet cable included with the router.

Connecting the Model RT311 router to your Local Area Network

The Model RT311 router has a single por t f or connection to your local network. This port is wir ed as a host rather than a hub, and is intended to connect to a hub or switch in your network. To connect the Model RT311 router to your LAN:

• Connect the LOCAL po rt of t he r out er to your existing Ethernet hub or swit ch usi ng the white straight-through Ethernet cable shipped with your router.

To connect the router to a single PC:

• Connect the LOCAL port of the router to the Ethernet port of your PC using the red Ethernet crossover cable shipped with your router.

If the Ethernet port of your PC op era te s at 100 Mbp s, you must use a Categ ory 5 rate d cable, such as the red Ethernet cable included with the Model RT311 router.

Connecting the Model RT314 router to your Local Area Network

The Model RT314 router incorporates a four-port switch for connection to your local network. To connect the Model RT314 router to your LAN:
