Chapter 1 Introduction 1.1 Product Introduction The ESG-103 is 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-103 pro- vides home users an environment protected by its NAT-type firewall. Because its WAN side is also an Ethernet interface, which is the same as its LAN interface

1.2.2 Three ways to acquire WAN's IP address There are three ways to acquire ESG-103's WAN IP address. The first one is to assign its WAN interface a static valid IP address. Second, users can also acquire ESG-103's WAN 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 provid- ers offer their clients IP addresses by DHCP protocol, and ESG-103 can act as

Chapter 3 Configuration This chapter describes the web-based ESG-103 configuration in detail. The ESG-103 broadband sharing router has a structured menu and a "Quick Installation Wizard" page to help user quickly set up their ESG-103. This chapter explains each of these menu sections. When the ESG-103 boots up at the first time, it has a default IP address “192.168.1.1” assigned to its LAN interface. In order to configure ESG-103, please point an Internet browser from the browsing host to http

3.1 Quick Installation Wizard 3.1.1 WAN Parameters ESG-103 provides three ways to get an IP address in its WAN interface- Fixed IP, DHCP, and PPPoE. There are three radio boxes in this configuration page and you can choose one of which is suitable for your access environment. If you are assigned a Static IP setting in your WAN port by the ISP provider, you have to choose Fixed IP mode and enter the settings, such as the IP address, IP subnet mask, and ISP gateway address, which you can get from

3.1.2 PPPoE Parameters When you choose to use PPPoE mode to acquire your WAN IP addresses, you should first set up PPPoE parameters to facilitate ESG-103 to communicate with your ISP. When you connect to your ADSL dial-in service, you need your PPPoE parameters given by your ISP. Username - When you apply for a PPPoE service from your ISP, they will give you a set of username and password for the purpose of login. You can key in your username from your ISP in this box. Password - Please enter yo

IP Address - Your IP address in LAN interface. Netmask - Subnet mask in your LAN interface. 3.1.4 Remote Control Parameters ESG-103 provides some remote control features to help user's remote man- agement for ESG-103. In this configuration tags, you can set up a dedicated remote host to control your ESG-103, reject or acce

hosts, whose IP addresses are not the one in Remote Control IP box. Ping Reply - If you do not like to let your ESG-103 respond to "Ping" packets from the Internet, you can disable the "Ping Reply." Or you can enable this feature to reply "Ping" packets. HTTP Public Port - In ESG-103, it has a built-in web server to process all configurations through the web browser. Its default listening port is 80, or you can assign the other port number instead of 80. If you also have a web server in your LAN

In ESG-103, you can get system information in "Status" page. ESG-103 divides this page into two parts, the WAN information, and the LAN infor- mation. This information is quite useful for users to see if the system is in a normal status. 3.3 Advanced Setting 3.3.1 DNS Setup In "DNS Setup" page, users can input two DNS name servers because ESG103 can use these two servers to complete its DNS relay function. Please note that the DNS relay is a default setting in ESG-103. However, ESG-103 chooses

3.3.2.2 DHCP Server Parameters ESG103 can act as a DHCP server in your LAN side. It helps users to acquire their IP addresses without making a lot of configuration. ESG-103 also offers hosts parameters shown below. Default Gateway - Tell hosts where they can deliver their packets if they do not know how to deal with those packets. In fact, it should be the ESG-103 itself. Netmask - Tell hosts their netmask. Name Server 1, 2, 3 - ESG-103 works as a DNS server to its hosts to help hosts activate

3.3.2.3 Table of fixed host entries DHCP server can assign IP addresses and some options, such as gateway's IP address, DNS server, etc., to hosts in ESG-103's LAN side. Usually, DHCP server assigns IP addresses dynamically. However, you can assign MAC address and IP address to be one pair. When DHCP server receive request from that host whose MAC address is one of those pairs in its mapping table, DHCP server will assign that mapping IP address to host. 3.3.3 NAT/DMZ Setup NAT is a mechanism
