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.

4.3.4 DMZ

Virtual DMZ exposes one client to the Internet, allowing this client to receive all inbound packets directed to your Local Area

Network.

Inbound traffic from the Internet is usually discarded and routed to a specific client only if port forwarding or a port trigger has been configured on the network. In a DMZ configuration, one network client receives all inbound packets.

Setting up DMZ on a network is useful when you need incoming ports open or you want to host a domain, web, or e-mail server.

Caution: Opening all the ports on a client to the Internet makes the network vulnerable to outside attacks. Please be aware of the security risks involved in using DMZ.

To set up DMZ:

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

> DMZ tab.

2. Configure the setting below. When done, click Apply.

IP address of Exposed Station: Key in the client’s LAN IP address that will provide the DMZ service and be exposed on the Internet. Ensure that the server client has a static IP address.

To remove DMZ:

1. Delete the client’s LAN IP address from the IP Address of

Exposed Station text box.

2. When done, click Apply.
