CONFIGURATION VIA TERMINAL Commands
You can use terminal emulation on your PC/workstation for the initial and future
configuration of your product. If you prefer, a telnet session can be opened directly. Telnet
provides the same type of terminal emulation. For security purposes, the product uses port
333 for telnet. All of the following Terminal Mode Configuration menus are identical in the
telnet session, with the exception that any saved changes that result in the product rebooting,
will require user to open a new telnet session to reestablish a connection with the product.
For more information on telnet configuration, please see “How to Start Telnet” section below
How to start Telnet
1.
The instructions below are for using this unit with its default settings (i.e. DHCP enabled,
Local Port IP address: 192.168.1.254, SubnetMask: 255.255.255.0).
2.
Go to StartÆRun.

PPP OVER ETHERNET (PPPOE)
What is PPPoE?
PPPoE is known as a dial-up DSL service. It is designed to integrate the broadband services
into the current widely deployed, easy-to-use, and low-cost dial-up-access networking
infrastructure. Thus, customer can get greater access speed without changing the operation
concept.
How can I know I am using PPPoE?
PPPoE client software is provided by our ISP and should be installed onto your computer
first. You run the program to connect/disconnect to the Internet. User Account information
(User Name and Password) is also required each time you connect to the Internet access.
Note: After you have entered the PPPoE information during the device setup, after starting
up the device, the device will provide your Internet Service the PPPoE information and login
automatically. It is not necessary to install and run the PPPoE software on the computers
and you can just uninstall the PPPoE software from your computers.
Checking PPPoE Connections
1.For GUI Setup program
1. Go to StartÆ ProgramsÆIP Share Setup.
2. When the configure screen appears, select the Global Port tab. Refer to the previous
section titled “Configuration in GUI”.
3. Check if the value of Global port IP address is 0.0.0.0, if it is, that means that the PPPoE
connection failed. If the value is non-zero, then the PPPoE connection is good.
2. Checking PPPoE status through Terminal Mode
1. Start Telnet as described in the previous section titled “Configuration in Terminal
Program” for terminal emulation.
2. At the command prompt, type show command.
command>show
3. If the string of IP address of global port is 0.0.0.0, this means you are not connected. If it
is anything other than 0.0.0.0 (non-zero), it means the connection is good.
Note: Once the PPPoE setup is completed on this device, do not run any PPPoE client
software on the local workstations.

FAQ
Factory Reset
If you have lost the device’s password or you would liek to set the device back to its default
state, you can do the Factory Reset. Performaing the Factory Reset will erase all
previously entered device settings.
To reset to factory default setting, go to the Management Utility window and click
the tool bar and then clikc “OK” to confirm the reset.
on
Figure 19
The fctory default values is detailed in the section Factory Default Settings.
“I can't find the product using the GUI Setup Software”
For the GUI Setup Software to find the device, it has to be accessed from a client. This
means that the computer you are trying to use to run the software must be setup as described
in the section Configuration in GUI. Also, the computer should be restarted to ensure that it
is receiving IP address from the device.
To verify that your computer’s TCP/IP protocol is setup properly, use the "winipcfg" utility
in Windows (95, 98, and ME). To run this, go to Start-->Run, type "winipcfg" in the Run box,
and then click “OK”. Make sure the Network Adapter Card is selected and then press the
"More Info" button on the bottom right hand corner. For Win2000 and NT stations, open
the “Command Prompt” (DOS window) and type in ipconfig /all and hit “Enter” to
obtain the adapter’s IP information.
Look at the box labeled DHCP Server, this should be the product's IP address (192.168.0.1 at
default). If it is not, or it is blank or reads 255.255.255.255 then you may have a cabling
problem, or you may have another DHCP server on your network. In either case, please
follow the installation guide again, and ONLY connect the device, the client, and your
modem together. If you are on a network, it is recommended that you contact your IS or IT
Manager for further assistance with DHCP settings. Placing an IP Sharing Device that passes
out IP addresses on a LAN with an existing DHCP server may cause problems throughout a
network. It is recommended you disable other DHCP serves on the network if you plan on
using this product on the network.
- 46 -
IP address conflict
When you see the message box prompted for IP address conflict, this means two or more
workstations have the same IP address. If you have setup the device as a DHCP server, on
the problem workstation, please run the "winipcfg" utility, select the correct Network
Adapter, click “release all” to release all current configuration first, then click “renew all” to
renew the IP information again. If the DHCP function is disabled and static IP addresses are
assigned to each workstation, please double check each workstation’s IP address for
duplicate IP.
My Internet application won't work
To protect your computer from Hackers on the Internet, this product uses “port blocking”
technology. A port is like a door into your computer. Each service on the Internet has an
associated port. The device protects your computer by closing certain ports, so that malicious
programs can't access your computer. However, if you are using an application that requires
communicating via one (or more) of these blocked ports, the application will not work. In
this case, you will have to manually open these ports to allow the application to work
properly.
Some applications that may be affected are
Some Email Programs (most of the e-mail programs should work fine)
Some Multi-Player Games
Some Internet Phone/Video Conferencing Applications (i.e. NetMeeting, ICQ,
PCanyWhere)
Also, there are some applications, which require reverse connection over the Internet. In
other words, when you are connected to these applications, you have to open your ports for
two-way connection.
The first thing you will need to do is determining what port (or ports) the application uses.
The fastest way to find this information is to go to the software maker's web site, go to the
support section, and look for information related to NAT, Proxy Server, or Firewall. This
information will typically list 1 to 3 ports that need to be opened for proper operation of the
software. If you can't find the necessary information, call the software maker and ask for
what ports need to be opened for the software to work through a firewall.
Once you have the necessary port information, follow the instructions below to setup the
“Virtual Server”.
A. Launch the Windows GUI Setup Software, click to select the device you want to
configure and click
on the tool bar to configure the selected device.
B. Choose the "Virtual Server" tab:
- 47 -
C. Enter one of the port numbers or a port range that your application requires. Press
"Browse" to select the Local server mapping to the port(s) number you just entered.
Figure 20
D. Select the internal server (the computer that is using the Internet Application) in the
following window.
Figure 21
E. Press Add. Repeat this process for each individual port you need to open.
F. Press Save. Wait 30 seconds for the device to reboot and then try the application again. It
may be necessary to restart your application or your computer for the application to recognize
the change.
Note: In rare occasion that the Internet Application requires a random number of ports to be
opened, in this case, configure the Virtual Server to open all ports (range from 1 to 65535
- 48 -
and both TDP and UTP ports). However, this makes your network vulnerable to Internet
attacks.
Can not access the Internet
For Cable Modem users, find the workstation’s “Computer” name and then input this
name in the device’s “Device/Computer Name” field. Do this only when your cable
Modem Internet Service Provider provides you with a specific “Computer Name”.
1. On the Workstation (95, 98, and ME), go to Start ÆControl Panel Æ Network, and
select Identification tab. Copy the Computer name as shown in the left figure below. For
Win2000, right click on “my computer”, select “properties”, click on “network
identifications”, click on “properties”, and then copy the computer name.
2. Run the GUI setup program, select the device, and click on “Configure” to go to the
Management tab.
3. Paste the name on to the field “Device/Computer Name” as shown in the right figure
below.
Figure 22
For DSL PPPoE users, open the Management page, at the PPPoE Username filed, enter
the Username follow by your ISP’s domain name and then click “Save”. For example,
username@earthlink.net, which is composed by username (provided by your ISP) followed
by your ISP’s domain name.

Check the physical connectivity of local network.
Check if both the LEDs of Local and Global on the product’s front panel are lit. If yes, go to
next step. Otherwise, make sure you are using the correct cables and the cables are
connected to the network devices properly. Push the MD/MDIX button once and see if the
LED lit up.
Check the physical connectivity of broadband device.
Examine the LED of LAN port and the LED of the broadband signal input on the Cable
Modem/xDSL Modem. If the LAN LED is off, make sure you are using the correct cables
and the cables are connected to the devices properly. If the LED of the broadband signal is
off, please contact your ISP.
Note: You can also call your ISP and make sure the Internet service is still online.
Check the status of this product.
If your ISP assigned you an IP address, please skip this step. Otherwise, use the telnet
program to “release” and “renew” the current IP address of the Global port. After that, type
“Show” command to see if “obtain global port configuration from ISP” shows the address is
“claiming” or “under claiming”. If the IP address is “claiming”, go to next step. If the result
is “under claiming”, reboot the product and check it again. If the result still is “under
claiming”, please contact your ISP and find out if the service is still available.
Check the logical connectivity from your computer to the Internet.
Refer to the section "PING.EXE" in the "TCP/IP Network diagnosis" chapter. Follow the
described steps to find out where the problem is.

Diagnosis
TCP/IP Network Diagnosis
Execute WINIPCFG.EXE or PING.EXE for TCP/IP network diagnosis.
WINIPCFG
The WINIPCFG program (for Win95, 98, and ME) is used to gather information about the
TCP/IP connections that are active on your system. It cannot be used to dynamically adjust
TCP/IP connections. You can also renew leases (if allowed by the network), and get the
current IP address assignments through this program.
From Windows, go to Start, click Run, enter WINIPCFG, and click OK.
Figure 24: Run
The following figure displays the adapter address and current TCP/IP address.
Note: At the “Ethernet Adapter Information”, select the correct Ethernet adapter that is
installed in this computer.
Select the
correct
Ethernet
adapter.

Figure 26: IP Configuration
On the top, the “Host Name” and “DNS server” of the computer are configured to call when
it is looking for a named resource. The default gateway is the server through which the client
connects to the Internet. The DHCP Server identifies the network server that assigns IP
addresses to computers on the network.
If the product is working properly, the following should be apparent from this screen:
1) The Client should have an IP address within the prescribed range.
2)
The “DHCP” and “Default Gateway” should list the product’s local port address
(the device’s IP address).
3) The DNS server IP addresses should match the DNS server IP addresses set in the
device.
IPCONFIG
For Win NT and Win2000, go to “Start”Æ”Programs”Æ”Accessories”Æ”Command
Prompt” to open the Command Prompt. Type in IPCONFIG /ALL and hit “Enter” to see the
adapter’s information. Type in IPCONFIG /RELEASE to release all adapters’ IP address
- 52 -
and IPCONFIG /RENEW to renew IP addresses. For a list of the IPCONFIG commands,
type in IPCONFIG /? .
PING.EXE
Ping is used to verify that a computer is active and available. Users can ping a specific
destination domain name or just the IP address.
Example:
For example, to find the server 168.95.192.1, type the following command at the MS-DOS
prompt and then press “Enter”:
C:\>ping 168.95.192.1
PING can be executed in Windows as shown below:
1.
Go to the Start menu.
2.
Click Run.
3.
Type ping 168.95.192.1 and click OK.
4.
The server (IP address) is online if the following message appears.
Reply from 192.168.0.1: bytes=32 time=3ms TTL=100
5.
The destination device is not reachable if the following message appears.
Reply from 192.168.0.1: Destination host unreachable
or Request timed out.
ISP Connectivity Checkup
Issue a PING command to the IP address of your ISP’s Gateway or DNS server.
Note: If the global port was set to obtain configuration automatically, you need to check
Gateway and DNS server information under “Global Port” via the Windows GUI setup
program.
For Example:
From the GUI setup program, if the DNS server address is 203.66.81.254, at C:\> prompt,
enter Ping 203.66.81.254. If successful, you can reach your ISP server.
If unsuccessful, you may have trouble connecting to your ISP, please verify that the product
is properly configured to connect to your ISP. Also verify that your Cable/DSL modem and
the line are functioning properly.
Internet Connectivity Checkup
PING to an IP address or domain name on Internet.
- 53 -
For Example:
C:\> PING 168.95.192.1 –w 5000
C:\> PING www.yahoo.com –w 5000
If successful, you are connected to the Internet.
If you can ping the ISP’s gateway, but cannot ping a specific site (e.g. www.yahoo.com) on
the Internet, chances are, your ISP has an internal problem. Please call them for support.
