• Trigger Port: Specify a trigger port to open the incoming port.

Protocol: Select the protocol, TCP, or UDP.

Incoming Port: Specify an incoming port to receive inbound data from the Internet.

Protocol: Select the protocol, TCP, or UDP.

NOTES:

• When connecting to an IRC server, a client PC makes an outgoing connection using the trigger port range 66660-7000. The IRC server responds by verifying the username and creating a new connection to the client PC using an incoming port.

• If Port Trigger is disabled, the router drops the connection because it is unable to determine which PC is requesting for IRC access.

When Port Trigger is enabled, the router assigns an incoming port to receive the inbound data. This incoming port closes once a specific time period has elapsed because the router is unsure when the application has been terminated.

• Port triggering only allows one client in the network to use a particular service and a specific incoming port at the same time.

• You cannot use the same application to trigger a port in more than one PC at the same time. The router will only forward the port back to the last computer to send the router a request/trigger.

4.3.3 Virtual Server/Port Forwarding

Port forwarding is a method to direct network traffic from the

Internet to a specific port or a specific range of ports to a device or number of devices on your local network. Setting up Port

Forwarding on your router allows PCs outside the network to access specific services provided by a PC in your network.

NOTE: When port forwarding is enabled, the ASUS router blocks unsolicited inbound traffic from the Internet and only allows replies from outbound requests from the LAN. The network client does not have access to the Internet directly, and vice versa.

To set up Port Forwarding:

1. From the navigation panel, go to Advanced Settings > WAN >

Virtual Server / Port Forwarding tab.

2. Configure the following settings below. When done, click

Apply.

Enable Port Forwarding: Choose Yes to enable Port

Forwarding.

Famous Server List: Determine which type of service you want to access.

Famous Game List: This item lists ports required for popular online games to work correctly.

FTP Server Port: Avoid assigning the port range 20:21 for your FTP server as this would conflict with the router’s native

FTP server assignment.

Service Name: Enter a service name.

Port Range: If you want to specify a Port Range for clients on the same network, enter the Service Name, the Port

Range (e.g. 10200:10300), the LAN IP address, and leave the

Local Port empty. Port range accepts various formats such as Port Range (300:350), individual ports (566,789) or Mix

(1015:1024,3021).

NOTES:

• When your network’s firewall is disabled and you set 80 as the HTTP server’s port range for your WAN setup, then your http server/web server would be in conflict with the router’s web user interface.

• A network makes use of ports in order to exchange data, with each port assigned a port number and a specific task. For example, port 80 is used for HTTP. A specific port can only be used by one application or service at a time. Hence, two PCs attempting to access data through the same port at the same time would fail. For example, you cannot set up Port Forwarding for port 100 for two PCs at the same time.

Local IP: Key in the client’s LAN IP address.

NOTE: Use a static IP address for the local client to make port forwarding work properly. Refer to section 4.2 LAN for information.

Local Port: Enter a specific port to receive forwarded packets.

Leave this field blank if you want the incoming packets to be redirected to the specified port range.

Protocol: Select the protocol. If you are unsure, select BOTH.

To check if Port Forwarding has been configured successfully:

• Ensure that your server or application is set up and running.

• You will need a client outside your LAN but has Internet access (referred to as “Internet client”). This client should not be connected to the ASUS router.

• On the Internet client, use the router’s WAN IP to access the server. If port forwarding has been successful, you should be able to access the files or applications.

Differences between port trigger and port forwarding:

• Port triggering will work even without setting up a specific

LAN IP address. Unlike port forwarding, which requires a static LAN IP address, port triggering allows dynamic port forwarding using the router. Predetermined port ranges are configured to accept incoming connections for a limited period of time. Port triggering allows multiple computers to run applications that would normally require manually forwarding the same ports to each PC on the network.

• Port triggering is more secure than port forwarding since the incoming ports are not open all the time. They are opened only when an application is making an outgoing connection through the trigger port.
