1Introduction

This chapter gives the introduction to the Broadband Router.

What’s in the Box?

Your Broadband Router box should contain the items listed below

•1 Broadband Router

•1 AC Adapter, AC 9V 1A

• 1 RS-232 serial cable with DB-9 (9 pin) male connector and RJ45 plug to

connect the Broadband Router Console/COM port and external ISDN TA/

Analog Modem

•1 female to female 9 pin adaptor to connect the Broadband Router Console port

to a PC COM port.

•1 CAT5 UTP cross-over LAN cable to connect the Broadband Router EWAN

port to an external ADSL or Cable Modem

Note: Some Cable Modems use straight LAN cable

•1 CD-ROM containing the online documentation

•1 Quick-Start Guide

Overview of the Broadband Router

The Broadband Router is a small desktop router that sits between your local Ethernet

network and a remote network (e.g., the Internet or a remote office). The Broadband

Router contains an EWAN port connecting toan external ADSL/Cable modem , a

Console/ COM port for connection to a console device(such as a PC COM port ), and

a four-port 10/100Mbps Ethernet switch for connection to PCs on your local network.

The Console/COM port can alsobe used to connect to the Internet(as a back-up such

as when the ADSL/Cable modem line is not operational) or a remote office via an

external ISDN TA or Analog Modem, and even allows a remote user(a tele-commuter

or a traveling sales person) to dial in and access your local network.

Data comes into the Broadband Router from the local LAN and then is “routed” to the

remote network, and vice versa.

Broadband Router Applications

The main functions of the Broadband Router

-to allow devices on your LAN to access the Internet,

-to allow access to the servers from the public network,

1-2

-to support remote users to directly dial in and access your LAN,

-to support direct dial-up communication with remote offices and share resources

between remnote LANs.

- to create Virtual Private Network (VPN) to allow remote LANs to share resources

with each other over the Internet.

Accessing the Internet

The most common use for the Broadband Router is to provide Internet access, so that

everyone on your LAN can surf the web and send/receive email or files.

The Broadband Router automatically acquires the necessary IP address when the

connection to the Internet is established. You don’t need to apply for and assign an IP

address to each PC or workstation on your network.

Accessing Servers from the Public Network

If you want special servers to be accessible by remote users across the Internet (e.g.,

an e-mail server, an FTP server, or a web server), you can configure the Broadband

Router to proxy the service from its own address. This means that the remote user can

address the router as if it were the special server and the Broadband Router will re-

direct this connection to the appropriate computer on the network.

Supporting Dial-in Access to Your Network

You can set up your Broadband Router to allow users to connect to your network

and share resources from home or while they’re travelling. The Broadband Router

built-in configuration program makes the necessary setup a snap. As a security

feature, after a user calls in, the Broadband Router can hang up and call that user

back at a preconfigured telephone number.

Figure 1-1 Dial-in Access

You can set up the Broadband Router to provide Internet access for everyone on your

LAN and allow a remote user to dial in to your network via V.90 Modem or ISDN TA

simultaneously.

Figure 1-2 Internet Access and Dial-in Simultaneously

Creating Your Own Private Wide Area Network

You can create your own private wide area network with Broadband Router via

external ISDN TA / modem and allow two or more remote networks to connect to one

another and share resources. The remote network can use a broadband router even

though it is a different vendor - as long as it also supports LAN to LAN

communications.

Figure 1-3 Connecting Two Networks with Broadband Router

You can set up the Broadband Router to provide Internet access for everyone on your

LAN and create your own private wide area network via V.90 Modem or ISDN TA

simultaneously.

Figure 1-4 Internet Access and LAN-to-LAN Simultaneously

Creating a Virtual Private Network (VPN)

Virtual Private Networking (VPN) provides a means to connect remote LANs over

the Internet, while only local toll charges to an Internet Service Provider are incurred

even if the two LANs are physically remote to each other.

To create a VPN between two sites, a special connection called “tunnel” followed by

a VPN data session has to be set up over the Internet. After a VPN data session is set

up, data can be sent over it, optionally encrypted to prevent unauthorized access.

Additionally, VPN tunnels allow IP, IPX and Bridging traffic to flow across the

Internet, including NetBIOS information (for Windows networking) encapsulated

within IP or IPX packets.

All information required for a VPN is defined in a VPN profile, which contains, for

example, the IP address of the VPN partner and authentication information (including

the encryption key that is used).

When a PC from one site tries to communicate with a device on the other site for the

first time, the VPN tunnel and data session establishment process will be triggered

automatically. For the originating side, first the destination IP address will be used to

search for the corresponding VPN profile. Based on the information conifgured in the

matched VPN profile, a VPN tunnel is created, a VPN data session will be created

and authentication information exchanged, then data traffic can start to flow. For the

destination side, when a VPN data session creation is requested, the router will base

on the originating IP address to search for a matched profile. Once found, the

Broadband Router will use the information in the matched profile to authenticate the

incoming "call", after which data transfer can begin.

More than one VPN data sessions can be established over the same tunnel.

See chapter 4 for detailed configuration instructions.

Figure 1-5 Creating a Virtual Private Network

A Configuration Example

In Figure 1-6, two Broadband Routers are installed in two different locations. They

are connected to the Internet via ADSL/Cable modem, allowing users to surf the

Web. They are also connected to each other through the telephone network, forming a

private company network.

Figure 1-6 Connecting Two Private Networks

This example illustrates an important feature of the Broadband Router: a private

device can be accessed from the Internet by mapping the application port number to a

port number on the Broadband Router. In this case, an Internet user accesses a web

server with IP address 206.112.113.6, which is the Broadband Router’s IP address.

When properly configured, the Broadband Router will translate that port 80 of that

address to port 80 of the private IP address, 192.168.168.112.

In this example, all devices on both LANs (except for the Web servers) are

configured to obtain their IP addresses automatically (i.e., from the built-in DHCP

server in the Broadband Router). It is important for the Web Server on LAN #1 to

have the same IP address all the time (so that users can use the same IP address to

access it), it also means the Broadband Router should also be assigned a static IP

address.

IP addresses assigned to the devices on the LAN are only used in the local LAN

environment (with default IP network address of 192.168.168.0), therefore these

devices naturally form a private network and are not accessible by users across the

Internet, unless they are mapped. It is still possible to assign public IP addresses

obtained from your ISP to devices on your LAN so that they can be accessed by users
