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, 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-103 connects one Ethernet interface, which is from ADSL/Cable  
modem's LAN side as its WAN interface. It provides users in its 10/100  
base-TX LAN 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'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  
a DHCP client in its 10/100 base-TX WAN side to acquire its WAN IP  
address. In fact, ESG-103 is an outstanding device, which provides a 10/100  
base-TX WAN port.  
1.2.3 Act as a DHCP server in its LAN side  
ESG-103 can 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-103 will 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-103 and remote  
users in the Internet can access these inside servers by ESG-103's virtual  
server function.  
1.2.5 Firewall via NAT (Network Address Translation)  
ESG-103 also plays a role of NAT-type firewall. A NAT-type firewall 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-103 by their own web browsers (IE or  
Netscape). This means that users wherever they are can manage ESG-103  
without any proprietary application installed in their PC.  
Chapter 1 Introduction - 2  
 
1.2.7 Firmware Upgrade  
ESG-103 provides 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.

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://192.168.1.1 and you will be pre-  
sented with the log in screen as shown below. You must log in with the cor-  
rect user name and password to start the ESG-103 configuration in a MD5  
authenticated web session. For setting up this MD5 authenticated session,  
the default user name is “admin”, and the default password is also  
“admin”. We strongly recommend that - you should change the root pass-  
word as described in the Admin Password section.  
Once your log-in is successful, you will be presented with a welcome web  
page. In that page, you can proceed with ESG-103 configuration or link to  
BenQ's web site for advanced information.  
Chapter 3 Configuration - 8  
 
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 the ISP provider. If you have a DHCP server  
coexisting in your WAN port or your ISP (NSP) provides DHCP services for  
you, then you can choose DHCP Client mode to acquire an IP address to  
access the Internet. Most of the ADSL service providers not only provide  
their customers dedicated IP address but also provide dial-in service. If you  
apply for dial-in service from your ISP, you can choose PPPoE to access  
Internet unless your ISP provider does not provide PPPoE as its dial-in  
solution.  
In brief, most ADSL users use PPPoE mode to get an IP from their ISP or  
NSP and cable modem users use DHCP mode to connect with ISP. Finally, if  
you ISP or NSP assign you a fixed IP address, you should configure it in Fixed  
IP mode.  
IP Address - This is WAN interface's IP address.  
Netmask - This is WAN interface's subnet mask.  
Default Gateway - When ESG-103 has no idea where it can forward  
packets, it deliver those packets to its default  
gateway.  
Chapter 3 Configuration - 9  
 
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 your password which comes from your ISP in this  
input field.  
Password Confirm - Type your password again, and this will confirm your  
password's value again.  
Maximum Idle Time - ESG-103 provides a timeout mechanism and this  
means if there is no any traffic pass through ESG-  
103 during the time that you set up, ESG-103 will  
terminate this link between you and your ISP  
automatically.  
Server Name - Some ISPs provide server name to be an authentication  
issue, so you need to give your server name from your ISP  
for valid login. If your ISP does not ask for server name,  
you can leave it blank or ignore it.  
Service Name - Some ISPs also provide service name to be an  
authentication issue, so you need to give your service  
name from your ISP for valid login. If your ISP does not  
Chapter 3 Configuration - 10  
 
ask for service name, you can leave it blank or ignored  
it.  
3.1.3 LAN Parameters  
This configuration can help you to set up your LAN interface's IP address  
and its subnet mask.  
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 accept "Ping" packets from  
the Internet, and set up the listening port of ESG-103's built-in web server.  
Remote Control IP - ESG-103 can be managed by a dedicated host, which  
is located in anywhere in the Internet, if you fill a  
host's IP address into this input field. Please note  
that if you have configured this feature, you could  
not change your ESG-103 setting by any other  
Chapter 3 Configuration - 11  
 
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 interface, it is useful that you would like to  
set it up as a web virtual server.  
3.2 Information  
3.2.1 Statistics  
This configuration page can bring the data traffic information to user who  
would like to know the quantity of received or transmitted Ethernet packets  
in ESG-103. You can see the amount of received or transmitted packets and  
bytes, and this information will be dynamically changed updated every three  
seconds.  
3.2.2 Status  
Chapter 3 Configuration - 12  
 
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 ISP's DNS server to be the first choice to relay its DNS  
packets, if user use PPPoE or DHCP client to connect to Internet. These two  
Chapter 3 Configuration - 13  
 
DNS servers appeared in the web page are to be the second and third prior-  
ity to relay DNS packets by ESG-103.  
DNS Name Server 1 - First backup DNS server. Since we use the DNS  
server offered by ISP to be the first choice to  
complete DNS relay function.  
DNS Name Server 2 - Second backup DNS server.  
3.3.2 DHCP Setup  
3.3.2.1 DHCP Clone MAC Address  
ESG-103 provides "MAC clone" function to let users change their WAN  
MAC address. This feature is provided for authentication purpose if your ISP  
would like to ask you to offer this information.  
Host Name - Your host's name.  
MAC Address - MAC address that you want to change in your WAN  
interface. Generally, this MAC address will be the authen-  
ticated information to offer to your ISP or NSP.  
Chapter 3 Configuration - 14  
 
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 their DNS function. Since ESG-103  
has DNS relay function, it offers hosts to be a  
default name server.  
DHCP Start IP - In ESG-103, there are 100 IP addresses at most can be  
assigned to hosts. You can assign an IP address to the  
host in this box from 192.168.1.1 to 192.168.1.253.  
DHCP End IP - This field will be filled in automatically.  
Chapter 3 Configuration - 15  
 
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 that can convert your private IP addresses into a single  
public IP address. In ESG-103, we offer dynamic NAT, static NAT, and  
NAPT functions. Dynamic NAT means that you can assign a range of pri-  
vate IP addresses to map to a range of public IP addresses in the WAN inter-  
face. When one public IP address is mapped to one host, this public IP  
address could not be assigned to the other hosts. Static NAT means you  
can set up a private IP address and public IP address to be a pair. In ESG-103,  
you can set up to 5 set static NAT. This function is very similar to DMZ  
(demilitarized zone). In ESG-103, it also acts as "Virtual DMZ" host setting.  
NAPT is a special function of NAT. NAT records packet's Port and IP  
address, converts it into public IP address in the WAN side and gives this  
session one unique port number. Most of the famous applications are sup-  
ported by ESG-103 such as HTTP, FTP, Telnet, NetMeeting, RealPlayer,  
QuickTime, ....etc. NAT is a default function in ESG-103.

3.3.3.1 Table of current virtual server entries  
Sometimes, there are many servers located in the LAN side and wish to be  
accessed by any remote host. However, they cannot be accessed directly  
because of NAT. We could use Virtual Server to let remote hosts access  
internal servers. In this configuration page, you can enter a public port that is  
bound on a server in the LAN interface. For example, FTP server's public  
port is 21, Telnet server's public port is 23, and HTTP server's public port is  
80. After that, you should offer a host that maps to this public port. In  
configuration figure below, you can map port 21 to the host whose IP  
address is 192.168.1.101 and the remote host can access FTP server in the  
LAN interface by accessing 211.21.83.14 through FTP client application  
installed in the remote host itself. When you access ESG-103's WAN side,  
the ESG-103 can convert your FTP packets and let them pass through the  
NAT.

Protocol - Select the protocol type the server provides?  
Chapter 3 Configuration - 17  
 
Service Name - Name this service in 10 characters.  
Port Number - The port is opened to others in the Internet side.  
Server IP Address - The server's private IP address in the LAN side  
Server Port Number - The port of the inside server which is listening  
3.3.3.2 Dynamic NAT  
In the first table, you can assign a range of private IP addresses that can be  
converted to public ones.  
Base Address - The first IP address that you wish to be converted from  
private to public.  
Number of Address - The number of the private IP addresses which are  
configured by users. Ex. If you have five hosts to  
be converted to public IP addresses, you can put 5  
in this box.  
Chapter 3 Configuration - 18  
 
In the second table, you can assign a range of public IP addresses that will be  
mapped to any private IP addresses in the first table.  
Base Address - The first Public IP address that you wish to be mapped to.  
Number of Address - The number of the public IP addresses which are  
configured by users. If you have ten IP addresses  
to be mapped to private IP addresses, you can put  
10 in this box.  
3.3.3.2 Static NAT  
The ESG-103 provides static NAT function, which also acts as virtual DMZ.  
It means that you can put your server in the LAN side and give it a mapped  
public IP address. It looks like you provide your server accessed by anyone in  
the Internet. (Please be carefully to use this feature.) You can also regard this  
function as a one-to-one mapped NAT function. Please be careful that all  
traffics that do not meet NAT requirement can be dealt with NAPT.  
Local Address - Local host's IP address  
Global Address - The public IP address will be mapped to a private IP  
address. Please note that users cannot change the first  
global address in the first entry because ESG-103 can  
reuse the NAPT's WAN IP address to do the static  
NAT conversion.  
Chapter 3 Configuration - 19  
 
3.3.4 RIP Setup  
3.3.4.1 RIP Parameters  
ESG-103 can act as a router, which use RIP-v2 (Routing Information Proto-  
col version 2) to exchange routing information with other RIP routers. How-  
ever, the default value is "disable" in ESG-103. If you have to use RIP to deal  
with packets passed through ESG-103, you can choose "enable" to turn on  
this feature. "Enable" means RIP can be sent and received from that interface.  
3.3.4.2 Routing Table  
In ESG-103, you can add or delete route into or from Routing Table. If you  
would like to forward packets to a specific host, you can add a static route  
for that host.  
Chapter 3 Configuration - 20  
 
Network Address - Host or network that you would like to forward your  
packets  
Netmask Address - Network mask.  
Gateway Address - Host that you would like packets to go from.  
3.4 Backup Dial Line  
When your broadband Internet does not work or disconnected, you can use  
dial-up modem as a backup line of ADSL modem through the RS232 connec-  
tion port, the backup line port. The ESG103 broadband router will detect  
the broadband Internet automatically. Whenever the broadband Internet is  
available again, ESG103 will switch back through the WAN port and the  
backup line will be disconnected automatically.  
Backup Line - Enable or Disable the backup line when the original link is  
failed.  
Phone number - The telephone number of the ISP.  
Username -user name for login.  
Password - password for login.  
Modem Setup String - The AT command string to setup the modem.  
Modem Hang Up String - The AT command string to hang up the  
modem.  
ISP - ISP profile that you are using.  
Chapter 3 Configuration - 21  
 
3.5 Admin Password  
This section explains how to change the "admin" password on the ESG-103  
broadband sharing gateway. We recommend that you keep the admin pass-  
word secret, and change it periodically. You can go to Change Password  
screen by selecting Change Password tab. The Password Setting dialog  
appears as shown below.  
Username - Enter your username, which you would like to use. Password  
can be any alphanumeric string up to 16 characters in length.  
New Password - Enter your new "admin" password in this field. Password  
can be any alphanumeric string up to 16 characters in  
length.  
Password Confirm - Reenter your "admin" password in this field to con-  
firm it again.  
3.6 Save Setting  
If you have already configured you ESG-103 and hope to save your configura-  
tion, you have to select "Save Setting" page to save all your configurations.  
Attention: After you have saved you configurations, ESG-103 will prompt  
"Reboot System" page to ask you to reboot your system. It is necessary to  
reboot ESG-103 to ensure you configurations are activated.  
Chapter 3 Configuration - 22  
 
3.7 Reboot System  
ESG-103 offers a remote reboot function to reboot your ESG-103. This  
means that users do not need to get to their ESG-103s to reset systems.  
Attention: Whenever you change the configuration of ESG-103, you must  
reboot your ESG-103 to activate the new configuration.  
3.8 Update Firmware  
ESG-103 provides a firmware update function through your web browser. If  
you would like to change your firmware version, you can go to the website  
htttp://192.168.1.1 to update or change your firmware, and then click the  
"Upgrade" button to begin the updating process. The process needs one  
minute, so ESG-103 will pop up a page to ask users to wait for one minute.  
When all procedures have been done, the web browser will connect to ESG-  
103's web server automatically, and please be carefully not to turn off  
the power of ESG-103 before all progresses completed.  
Chapter 3 Configuration - 23  
 
3.9 Load Default Setting  
Every ESG-103 has its default setting when shipped to users. It can prevent  
you from mistakenly setting up the configurations and making ESG-103 work  
abnormally. If this situation happens, you can go to the web page shown  
below and try to down load ESG-103's default setting. After loading, the con-  
figuration will restore back to default setting and your previous configuration  
will disappear.
