Advanced Help
The Wireless section under Advanced contains three sections for further configurations.
Multiple connections are required by some applications, such as internet games, video conferencing, Internet telephony, and others. These applications have difficulties working through NAT (Network Address Translation). This section is used to open multiple ports or a range of ports in your router and redirect data through those ports to a single PC on your network.
DMZ means "Demilitarized Zone." If an application has trouble working from behind the router, you can expose one computer to the Internet and run the application on that computer.
When a LAN host is configured as a DMZ host, it becomes the destination for all incoming packets that do not match some other incoming session or rule. If any other ingress rule is in place, that will be used instead of sending packets to the DMZ host; so, an active session, virtual server, active port trigger, or port forwarding rule will take priority over sending a packet to the DMZ host. (The DMZ policy resembles a default port forwarding rule that forwards every port that is not specifically sent anywhere else.)
Note: Putting a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as a last resort.
In a home setting, parents can also restrict the time and day of the week certain computers can access the Internet.
You would only like to allow your child to access the Internet from Monday to Friday, and from 7:00pm to 9:00pm only.
Filters can be configured to manage your incoming and outgoing traffic. Click on the , and buttons to advance to the next section for further configuration.
When you use the Port Triggering or Port Forwarding features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN to cyberattacks from the Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP addresses of Internet hosts that you trust to access your LAN through the ports that you have opened. You might, for example, only allow access to a game server on your home LAN from the computers of friends whom you have invited to play the games on that server.
Inbound Filters can be used for limiting access to a server on your network to a system or group of systems. Filter rules can be used with Port Triggering features. Each filter can be used for several functions; for example a "Game Clan" filter might allow all of the members of a particular gaming group to play several different games for which gaming entries have been created. At the same time an "Admin" filter might only allow systems from your office network to access the WAN admin pages and an FTP server you use at home. If you add an IP address to a filter, the change is affected in all of the places where the filter is used.
Outbound Filters can be used to limit LAN computer from accessing the Internet. Filters can be used with Port Forwarding features. Outbound filter can be used in conjunction with the Inbound Filter to allow incoming and restrict outgoing access when playing a game over the Internet or simply downloading a file.
This allows you to prevent your router from Denial of Service(DOS) attacks.
Domain Name Server(DNS) is a server that translates URL/Domain Names to the corresponding IP address. Since URL/Domain Names are alphabetical, they are easier to remember. But the Internet is based on IP address.
Routing
Schedules can be created for use with enforcing rules. For example, if you want to restrict web access to Mon-Fri from 3pm to 8pm, you would create a schedule selecting Mon, Tue, Wed, Thu, and Fri and enter a Start Time of 3pm and End Time of 8pm.
