5.6-2 Advanced Settings- Port Forwarding
Port Forwarding:
From the Forwarding tab, you can set up public services on your network, such as web servers, ftp servers,
or E-mail servers. When users send this type of request to your network via the Internet, the Server will
forward those requests to the appropriate PC. Before using Forwarding, you must disable the Server’s
DHCP function from the DHCP tab and assign the Router a new static LAN IP address, as the IP address
may change when using the DHCP server.
IP Address: Enter the IP Address of the server that you want Internet users to be able to access.
Start Port: Enter the Start port number of the range.
End Port: Enter the End port number of the range.
Protocol: On the same line, select TCP, UDP or Both.
Enable: Click Enable to enable it. The range of the Ports will be available for certain IP Forwarding.
Ex. If you set up the Local IP address as 192.168.0.10 and Start Port numbers as 1000, End Port numbers as 5000,
then select the Protocol as Both and click on Enable. You can now set up a public service such as FTP servers on your
network and set it’s port numbers as 2000. Then when the public IP want to access the FTP which linstening port
numbers is 2000, the Router will forward the request to 192.168.0.10. If it’s listening port numbers is not 2000 or it’s
range is out of the range the Router will block it.
After the settings is done, click on Apply to enalbe it.

5.6-2 Advanced Settings- Port Triggering
Port Triggering:
Port Triggering allows the Router to watch outgoing data for specific port numbers. The IP address of the
computer that sends the matching data is remembered by the Router, so that when the request data
returns through the firewall, the data is pulled back to the proper computer by way of IP address and port
mapping rules.
Triggerred Range: Enter the Start Port and the End Port.
Target Range: Enter the Start Port and the End Port.
Protocol: On the same line, select TCP, UDP or Both.
Enable: Click on Enable to enable it. The range of the Ports will be Triggering.

DMZ Host:
From the DMZ Host screen, you can allow one local user be exposed to the Internet to use a
special –purpose service such as Internet gaming or videoconferencing. Whereas IP Forwarding can only
forward a maximum of ten ranges of ports, DMZ hosting forwards all the points for one PC simultaneously.
DMZ Address: To exposure one computer, enter the computer’s IP address.

5.6-2 Advanced Settings- RIP Setup
RIP Setup:
With RIP Setup screen shown above, you have to manually adjust to physical changes in the network’s
layout. The Router, using the RIP protocol, determines the network packet’s route based on the fewest
number of hops between the source and the destination. The RIP protocol regularly broadcasts routing
information to other routers on the network. To set up RIP table, please follow the settings.
RIP Support: Click On or Off to enable or disable the RIP function.
RIP Authentication: Click Enable to decide the Authentication function.
RIP Authentication Key: Give the Authentication key when Authentication function is enabled.
RIP Authentication Key ID: Give the Authentication key ID when Authentication function is enabled.
RIP Reporting Interval: Enter the RIP Reporting Interval.
RIP Destination IP Address: The Destination LAN IP is the address of the remote network or host to which you want
to assign a static route. Enter the IP address of the host for which you wish to create a static route here. If you are
building a route to an entire network, be sure that the network protion of the IP address is set to zero. For example, the
Router’s standard IP address is 192.168.0.1. Based on this address, the address of the network to which the Router is
connected 192.168.1.X. Therefore you would enter the destination IP address as 192.168.1.0 if you want to route to
the router’s entire network, rather than just the router. Finally, enter the appropriate RIP Destination IP Address.
RIP Destination IP Subnet Mask: The Network Mask determines which protion of an IP address is the network
protion, and wich protion is the host protion. In the example above, the Network Mask is 255.255.255.0. This
determines that the first three numbers of an network IP address identify this particular network, while the last
digit(from 1 to 254) identifies the specific host. Finally, enter the appropriate RIP Destination IP Subnet Mask.
After the settings is done, click Apply to enalbe it.

Chapter 6: Troubleshooting
If the suggested solutions in this section do not resolve your issue, contact your system administrator
or Internet service provider.
Can I use the same cable line for TV and cable modem?
A. Yes, the TV and cable modem uses the cable line. You need a splitter to use them at the same time. Ask Cable
Company to install the splitter for you to avoid signal degradation.
My cable modem cannot get a solid green light on the Status LED when I connect the
cable back.
A. The cable modem lost the signal during the disconnection period and it will keeps scanning
other available signal. When you connect the cable back, it might take a while to find the
correct channel. You can power cycle the modem to speedup the process since modem will
remember the channel last time and it will start from that channel at startup.
How do I see my IP address?
A. If you are using Windows 95/98/Me, the winipcfg command will show you to IP address of the PC connected to
the cable modem. Notice that even though you seem get the same address all the time, it may still be a dynamic
address.
I have a cable modem. How can I make it work?
A. Basically, modem is plug and play. You can just connect the modem and you are ready to go if you have the
subscription. For ensure good signal for your cable modem, you should ask your cable provider to install the
cable modem for you.
Cannot Establish Wireless Link to Cable RG
A.
If you cannot establish an association with the Cable RG
• Make sure the power to the Cable RG is connected and turned on (LED
will light on the Wireless).
• Make sure the Cable RG and wireless clients are configured with the same
SSID.
• Make sure the Wired Equivalent Privacy is correctly configured for both
Cable RG and your wireless LAN card.
Note: For some cards, only Open-key can be selected as authentication
algorithm!
•
Reboot the Cable RG if necessary.
