ADVANCED FEATURESYour Cable/DSL Router has five advanced features:
To use DMZ Hosting, IP Forwarding, or IP Filtering, you must set a static IP address for that PC under the TCP/IP Settings tab. You can use DHCP and a static IP address at the same time, which ensures that your PC will automatically have an IP address pulled, whether or not you manually assign a static IP address. The Router uses IP addresses that start with 192.168.1.( ). If the IP address is static, the last number is between 2 and 99. If the IP address is dynamic, the last number is 100 or greater. For example, 192.168.1.43 is a static IP address. 192.168.1.127 is a dynamic IP address. To set a static IP address, make sure to enter all four pieces of data below under the Setup Tab of the Setup Window:
*DNS server data can be found under the Status tab of the Router or by calling your ISP. You may have two or three sets of DNS data - enter in all the DNS Server data you have. On the DNS tab under TCP/IP, enable DNS. In the Host section, enter any name you choose. You can even use your PC's name, which you can find under the Workgroup tab. Under the Domain Name, enter the domain name of your ISP. In the DNS server, input all the DNS data. Bring up the TCP/IP configuration window to confirm all the data is entered correctly.
At the prompt, type in "Ipconfig/all," which will display all the TCP/IP data for your PC.
Click on the Start button and select Run. Type in "Winipcfg" and press Enter
to access the TCP/IP data for your PC's network adapter.

| IP Address | 192.168.1.2-99 |
| Subnet Mask | 255.255.255.0 |
| Default Gateway | 192.168.1.1 |
| DNS Server Data | * from your ISP |
*DNS server data can be found under the Status tab of the Router or by calling your ISP. You may have two or three sets of DNS data - enter in all the DNS Server data you have.
If a piece of info is missing, go back to the Setup tab and input that data.
DMZ Hosting (Demilitarized Zone)
DMZ Hosting allows one user to be exposed to the Internet, bypassing the Router's firewall security while the rest of the network remains protected.
The DMZ feature exposes a single PC outside the firewall. If you are trying to run video-conferencing or programs that require 10 ports or more to be opened, use the DMZ feature.
Caution! When using the DMZ feature, you do not have firewall protection for that PC.
In the Router Setup window, click on the "Advanced" tab, then click on the "Forwarding" tab.
Enter the IP address of the PC you want to set in the DMZ zone. Click Apply when you're done.
IP Forwarding
If you need to forward more than 10 ports to a specific IP address, set up DMZ Hosting for that PC instead of using IP Forwarding. DMZ Hosting opens up all ports for one IP address.
IP forwarding can be used for email servers, Web servers, PC Anywhere®, Telnet, and more.
- Access the Router Setup Window by typing 192.168.1.1 in your browser's Address field.
- Once you have entered your correct username and password to display the Setup Window,
click on the "Advanced" tab, then click the "Forwarding" tab.
- Under the "Forwarding" tab, enter the port(s) that your application uses under the "Service Port" field(s) -
type in a number for each of the ports. Both the TCP and UDP ports are activated once
you enter a port number in the field.
- Then enter the IP address of the PC on the network that you would like the data to be forwarded to.
Remember to assign a static IP address to that PC.
- Click on Apply.
IP Filtering
Filtering blocks specific users on your network from accessing the Internet by closing ports on your Router's firewall. Filters can be set up either through an IP address or a specific network port.
The Filtering feature can only block users from all Internet access, and cannot be used to block specific sites.
Modifying Filter Settings
- Enter the IP addresses you wish to filter into the IP Address fields. Click Apply when you are done.
The users with those IP addresses will not be able to access the Internet.
- You can also filter users by entering their network port number. Enter the port numbers you want to
filter into the port numbers fields. Users who are connected to the Router will no longer be able
to access any port number listed there.
Blocking WAN Requests
- By enabling the Block WAN Request feature, you can prevent your network from being "pinged," or detected
by other Internet users. It also adds another layer of security to your network
by hiding your network ports. Both functions of the Block WAN Request feature
make it more difficult for outside users to work their way into your network.
- Under the "Filters" tab, which is under the "Advanced" tab, select "Enable" and click Apply.
