Port Range Forward

Port Range Forwarding allows you to set up public services on your network, such as web servers, ftp servers, e-mail servers, or other specialized Internet applications. Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. When users send this type of request to your network via the Internet, the router will forward those requests to the appropriate PC.

If you only want to forward a single port, see Port Forwarding.

Note

Any PC whose port is being forwarded must have a static IP address assigned to it because its IP address may change when using the DHCP function.

To add a new Port Range Forwarding rule, click Add and fill in the fields below. To remove the last rule, click Remove.

Enter the name of the application in the field provided.

Enter the number of the first port of the range you want to seen by users on the Internet and forwarded to your PC.

Enter the number of the last port of the range you want to seen by users on the Internet and forwarded to your PC.

Chose the right protocol TCP, UDP or Both. Set this to what the application requires.

Enter the IP Address of the PC running the application.

Click the Enable checkbox to enable port forwarding for the application.

Check all values and click Save Settings to save your settings. Click the Cancel Changes button to cancel your unsaved changes.

Port Forward

Port Forwarding allows you to set up public services on your network, such as web servers, ftp servers, e-mail servers, or other specialized Internet applications. Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. When users send this type of request to your network via the Internet, the router will forward those requests to the appropriate PC.

If you want to forward a whole range of ports, see Port Range Forwarding.

Note

Any PC whose port is being forwarded must have a static IP address assigned to it because its IP address may change when using the DHCP function.

To add a new Port Forwarding rule, click Add and fill in the fields below. To remove the last rule, click Remove.

Enter the name of the application in the field provided.

Enter the number of the external port (the port number seen by users on the Internet).

Chose the right protocol TCP, UDP or Both. Set this to what the application requires.

Enter the IP Address of the PC running the application.

Enter the number of the internal port (the port number used by the application).

Click the Enable checkbox to enable port forwarding for the application.

Check all values and click Save Settings to save your settings. Click the Cancel Changes button to cancel your unsaved changes.

Port Triggering

Port Triggering allows you to do port forwarding without setting a fixed PC. By setting Port Triggering rules, you can allow inbound traffic to arrive at a specific LAN host, using ports different than those used for the outbound traffic. This is called port triggering since the outbound traffic triggers to which ports inbound traffic is directed.

If you want to forward ports to a PC with a static IP address, see Port Forwarding or Port Range Forwarding.

To add a new Port Triggering rule, click Add and fill in the fields below. To remove the last rule, click Delete.

Enter the name of the application in the field provided.

Enter the number of the first and the last port of the range, which should be triggered. If a PC sends outbound traffic from those ports, incoming traffic on the Forwarded Range will be forwarded to that PC.

Enter the number of the first and the last port of the range, which should be forwareded from the Internet to the PC, which has triggered the Triggered Range.

Click the Enable checkbox to enable port triggering for the application.

Check all values and click Save Settings to save your settings. Click the Cancel Changes button to cancel your unsaved changes.

Note

Remember to save your changes before adding another triggering rule.

Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) is a set of computer network protocols. This Microsoft technology is for automatic configuration of devices. The goals of UPnP are to allow devices to connect seamlessly and to simplify the implementation of networks in the home and corporate environments. UPnP achieves this by defining and publishing UPnP device control protocols built upon open, Internet-based communication standards.

The UPnP forwards table shows all open ports forwarded automatically by the UPnP process. You can delete forwards by clicking the trash can or click the Delete All button to clear all forwards.

Allows applications to automatically setup port forwardings.

If enabled, all UPnP port forwardings are deleted when the router starts up.

If enabled, a presentation url tag is sent with the device description. This allows the router to show up in Windows's My Network Places. 

Note

When enabling this option you may need to reboot your PC.

Demilitarized Zone (DMZ)

The DMZ (DeMilitarized Zone) hosting feature allows one local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port Forwarding feature is more secure because it only opens the ports you want to have opened, while DMZ hosting opens all the ports of one computer, exposing the computer so the Internet can see it.

Note

Any PC whose port is being forwarded must should have a new static IP address assigned to it because its IP address may change when using the DHCP function.

To expose one PC to the Internet, select Enable and enter the computer's IP address in the DMZ Host IP Address field.

To disable the DMZ, keep the default setting, Disable.

Quality Of Service (QoS)

Bandwidth management prioritizes the traffic on your router. Interactive traffic (telephony, browsing, telnet, etc.) gets priority and bulk traffic (file transfer, P2P) gets low priority. The main goal is to allow both types to live side-by side without unimportant trafic disturbing more critical things. All of this is more or less automatic.

QoS allows control of the bandwidth allocation to different services, netmasks, MAC addresses and the four LAN ports. QoS is divided into four bandwidth classes called Premium, Express, Standard, and Bulk. Unclassified services will use the Standard bandwidth class.

You must choose whether to apply bandwidth limits to the WAN device or the LAN & wireless LAN device. (The LAN and wireless LAN ports are bonded internally into a single virtual device).

• HFSC - Hierarchical Fair Service Curve. Queues attached to an interface build a tree, thus each queue can have further child queues. Each queue can have a priority and a bandwidth assigned. Priority mainly controls the time packets take to get sent out, while bandwidth has primarily effects on throughput.
• HTB - Hierarchical Token Bucket, it is a faster replacement for the CBQ qdisc in Linux.HTB helps in controlling the use of the outbound bandwidth on a given link. HTB allows you to use one physical link to simulate several slower links and to send different kinds of traffic on different simulated links. In both cases, you have to specify how to divide the physical link into simulated links and how to decide which simulated link to use for a given packet to be sent. In other words, HTB is useful for limiting a client's download/upload rates, thereby preventing his monopolization of the available bandwidth. 

In order to use bandwidth management (QoS) you must enter bandwidth values for your uplink and downlink. These are generally 80% to 90% of your maximum bandwidth.

Bandwidth classification based on the four categories will be enabled first on the hardware ports, then on MAC addresses, then netmasks and finally services. For example, if you enable classification based on a MAC address, this will override netmask and service classifications. However, the LAN port based classification will work together with MAC, netmask and service classifications, and will not override them.

• Exempt - This class tries to keep the bandwith and packet flow untouched.
• Premium - The top bandwidth class. By default handshaking and icmp packets fall into this class. This class should be used sparingly. Occasionally VoIP service may be placed in this class so that voice receives top priority.
• Express - The Express class is for interactive applications that require bandwidth above standard services so that interactive apps run smoothly.
• Standard - All services that are not specifically classed will fall under the standard class.
• Bulk - The bulk class is only allocated bandwidth when the remaining classes are idle. Use this class for P2P services and downloading services like FTP.
