INTROUCTION
IP Share device is designed for IP address simplification and conservation, as it enables
private IP Internet works that use non-registered IP addresses to connect to the Internet. It
usually connects two networks together, and translates the private (not globally unique)
addresses in the internal network into single legal address before packets are forwarded onto
another network. Therefore, only one IP address is needed for the entire network to the
outside world. This provides additional security, effectively hiding the entire internal network
from the world behind that address.

Virtual Server
Being a natural Internet firewall, this IP Sharing device protects your network from being
accessed by outside users. When there is application that requires outside users to access
internal servers (e.g. Web Server, Ftp Server, e-mail Server or News Server), this device can act
as a virtual server to public services. You can set up a local server with specific port number
which stands for the service (e.g. web(80), FTP(21), Telnet(23)). When this device receives an
incoming access request for this specific port, it will be forwarded to the corresponding
internal server.

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?
A PPPoE client software provided by our ISP should be installed onto your computer first.
Run the program to connect/disconnect to the Internet each time before/after you surf.
An user account is also required each time you request the Internet access.
Checking PPPoE Connections
1.For GUI Setup program
1. Go to Start? Programs ?IP 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 the PPPoE
connection failed. If the Global Port IP is not all zeros, then the PPPoE connection is
successful.
2. Checking PPPoE status through Terminal Mode
1. Start Telnet or HyperTerminal 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 for any reason, e.g. password being forgotten, you have to reset this device to factory
default settings. By performing the Factory Reset, the current settings will be lost and the
settings are reseted to default.
The fctory default values is detailed in the section Factory Default Settings.
Figure 26
“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 98Me). 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.
Look at the box labeled DHCP Server, this should be the product's IP address (192.168.0.1 as
default). If it is not, or it is blank or reads 255.255.255.255 then you may have a cabling problem
(see above), 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 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.
IP address conflict
When you see the message box prompted for IP address conflict, this means two or more
workstations has the same IP address. If you have setup the device as a DHCP server, please
run the "winipcfg" utility to “release” all current configuration first, then “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, the 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 one 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
Some Multi-Player Games
Some Internet Phone/Video Conferencing Applications
Als o, 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 determined 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 and press "Find". Once the GUI Setup Software
finds the product, press "Configure":
