N450 Wireless Router WNR2500 This IP address must be in the same subnet as the base station, but different from the LAN IP address of the base station. 5. To prevent wireless clients from associating with the repeater and allow LAN client associations only, select the Disable Wireless Client Association check box. You can leave the check box cleared if you prefer wireless clients to be able to associate with the repeater. 6. In the Base Station MAC Address field, enter the MAC addresses for the access point that will function as the base station. 7. Click the Apply button. 8. Verify connectivity across the LANs. A computer on any wireless or wired LAN segment of the base station or a repeater can connect to the Internet.

Port Forwarding and Port Triggering Configuration Concepts By default, the router blocks inbound traffic from the Internet to your computers except replies to your outbound traffic. You might need to create exceptions to this rule for these purposes: • To allow remote computers on the Internet to access a server on your local network • To allow certain applications and games to work correctly when your router does not recognize their replies Your router provides two features for creating these exceptions: port forwarding and port triggering. The next sections provide background information to help you understand how port forwarding and port triggering work, and the differences between the two. Remote Computer Access Basics When a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing the source and destination address and process information. Before forwarding your message to the remote computer, your router must modify the source information and create and track the communication session so that replies can be routed back to your computer. Here is an example of normal outbound traffic and the resulting inbound responses: 1. You open a browser, and your operating system assigns port number 5678 to this browser session. 2. You type http://www.example.com into the URL field, and your computer creates a web page request message and sends it to your router. The message contains the following address and port information: Advanced Settings 86

Port Forwarding and Port Triggering Configuration
Concepts
By default, the router blocks inbound traffic from the Internet to your computers except replies
to your outbound traffic. You might need to create exceptions to this rule for these purposes:
To allow remote computers on the Internet to access a server on your local network
To allow certain applications and games to work correctly when your router does not
recognize their replies
Your router provides two features for creating these exceptions: port forwarding and port
triggering. The next sections provide background information to help you understand how
port forwarding and port triggering work, and the differences between the two.
