Chapter 1 Introduction

1.1 Product Introduction

The ESG-103is a broadband router, which is to provide home users a secure environment in their private side. It also acts as a Network Address Translation (NAT) device and let home users use private IP addresses to access the Internet from single or multiple global IP addresses.ESG-103provides home users an environment protected by itsNAT-typefirewall. Because its WAN side is also an Ethernet interface, which is the same as its LAN interface, you can easily plug it into any access device, such as an ADSL/ Cable modem or router, which provides Ethernet interfaces in the LAN side to run for NAT function.

Application Illustration

1.2.1 Being a router between two Ethernet interfaces

The ESG-103connects one Ethernet interface, which is from ADSL/Cable modem's LAN side as its WAN interface. It provides users in its 10/100base-TXLAN side which can share a single valid IP address. From this kind of configuration, users do not need to apply for a valid IP address for everyone in its LAN side to access Internet. This function can be enabled or disabled. If users apply for many public IP addresses for some purpose, they are also able to use those IP addresses to connect to the Internet.

Chapter 1 Introduction - 1

1.2.2 Three ways to acquire WAN's IP address

There are three ways to acquire ESG-103'sWAN IP address. The first one is to assign its WAN interface a static valid IP address. Second, users can also acquireESG-103'sWAN IP address by PPPoE and this functionality can help users need not to install PPPoE client software in their own hosts. The last one is to obtain WAN's IP address from DHCP server. Some service providers offer their clients IP addresses by DHCP protocol, andESG-103can act as a DHCP client in its 10/100base-TXWAN side to acquire its WAN IP address. In fact,ESG-103is an outstanding device, which provides a 10/100base-TXWAN port.

1.2.3 Act as a DHCP server in its LAN side

ESG-103can act as a DHCP server in its LAN side, and this functionality can help users need not to configure their own IP addresses. When users are booting their machines,ESG-103will assign each machine an IP address and other useful information, such as DNS server's IP address etc.

1.2.4 Virtual Server

Users can set up different kinds of servers behind their ESG-103and remote users in the Internet can access these inside servers byESG-103'svirtual server function.

1.2.5 Firewall via NAT (Network Address Translation)

ESG-103also plays a role ofNAT-typefirewall. ANAT-typefirewall provides users a secure LAN environment and prevents from being accessed by any anonymous people who desire to do something bad on your network.

1.2.6 Web Management

Users can configure and manage ESG-103by their own web browsers (IE or Netscape). This means that users wherever they are can manageESG-103without any proprietary application installed in their PC.

1.2.7 Firmware Upgrade

ESG-103provides an efficient way to upgrade the firmware. Users can use web browser to upgrade firmware and also can use TFTP client to do this job.
