Chapter 2. Wireless Settings | 1122. Wireless SettingsFor a wireless connection, you need to set up your wireless computer or device to use the gateway’s SSID, also called the wireless network name, and wireless security settings. NETGEAR strongly recommends that you use wireless security. This chapter includes:• Wireless Adapter Compatibility on this page• Security Basics on page 12• Add Clients (Computers or Devices) to Your Network on page 13• Wireless Settings Screen on page 14• Wireless Guest Networks on page 20• Set up Wi-Fi Multimedia on page 21Wireless Adapter CompatibilityA wireless adapter is the wireless radio in your PC or laptop that lets the PC or laptop connect to a wireless network. Most PCs and laptops come with an adapter already installed, but if it is outdated or slow, you can purchase a USB adapter to plug into a USB port.Make sure the wireless adapter in each computer in your wireless network supports the same security settings as the gateway. Note: If you connect devices to your gateway using WPS as described in Wi-Fi Protected Setup (WPS) Method on page 13, those devices assume the security settings of the gateway.
12 | Chapter 2. Wireless Settings Wireless Cable Modem Gateway CG2003D User Manual Security BasicsUnlike wired network data, wireless data transmissions extend beyond your walls and can be received by any device with a compatible wireless adapter (radio). For this reason, it is very important to maintain the preset security and understand the other security features available to you. Besides the preset security settings described above, your gateway has the security features described here and in Chapter 4, Content Filtering Settings.• Disable SSID broadcast• Restrict access by MAC address• Wireless security optionsDisable SSID BroadcastBy default, the gateway broadcasts its Wi-Fi network name (SSID) so devices can find it. If you change this setting to not allow the broadcast, wireless devices will not find your gateway unless they are configured with the same SSID. See Wireless Access Point Settings on page 16 for the procedure.Turning off SSID broadcast nullifies the wireless network discovery feature of some products such as Windows XP, but the data is still exposed to a determined snoop using specialized test equipment like wireless sniffers. If you allow the broadcast, be sure to keep wireless security enabled.Restrict Access by MAC AddressYou can enhance your network security by allowing access to only specific PCs based on their Media Access Control (MAC) addresses. You can restrict access to only trusted PCs so that unknown PCs cannot wirelessly connect to the gateway.The Wireless Station MAC address filtering adds additional security protection to the wireless security option that you have in force. Access List determines which wireless hardware devices are allowed to connect to the gateway by MAC address. See Advanced Wireless Settings on page 79 for the procedure.Wireless Security OptionsA security option is the type of security protocol applied to your wireless network. The security protocol encrypts data transmissions and ensures that only trusted devices receive authorization to connect to your network. There are several types of encryption: Wi-Fi Protected Access II (WPA2), WPA, and Wired Equivalent Privacy (WEP). WPA2 is the most recent, and is recommended if your equipment supports it. WPA has several options including pre-shared key (PSK) encryption and 802.1x encryption for enterprises. Note that it is also possible to disable wireless security. NETGEAR does not recommend this. You can view or change the wireless security options in the Wireless Settings screen. See Wireless Settings Screen on page 14.

Chapter 3. Content Filtering and Firewall Rules | 27Wireless Cable Modem Gateway CG2003D User Manual Port Forwarding and Port BlockingA firewall has two default rules, one for inbound traffic (WAN to LAN) and one for outbound traffic. • Inbound Rules (Port Forwarding) These rules restrict access from outsiders. The default rule is to block all access from outside except responses to requests from the LAN side. You can use port forwarding to add predefined or custom rules to specify exceptions to the default rule.• Outbound Rules (Port Blocking) These rules control access to outside resources from local users.The default rule is to allow all access from the LAN side to the outside. You can use port blocking to add predefined or custom rules to specify exceptions to the default rules. Set Up Port BlockingYou can use port blocking to block outbound traffic on specific ports. Note: Any outbound traffic that is not blocked by rules that you have created is allowed by the default rule.To configure port blocking and services to block specific outbound traffic:1. Select Advanced > Port Blocking. The Port Blocking screen displays.2. Under Add Predefined Service, select a predefined service from the Service field. (For example, FTP, which uses TCP ports 20 and 21.)

The Active Filters table now displays the list of ports that are currently forwarded.• To delete a service, select the radio button in the Active Filters table for the service that you want to delete, and then click Delete.Set Up Port ForwardingBecause the gateway uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a web server or game server) or computer visible and available to the Internet. The rule tells the Gateway to direct inbound traffic for a particular service to one local server or computer based on the destination port number. This is also known as port forwarding.Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
Chapter 3. Content Filtering and Firewall Rules | 29Wireless Cable Modem Gateway CG2003D User Manual To configure port forwarding and services for specific inbound traffic:1. Select Advanced > Port Forwarding. The Port Forwarding screen displays.2. Under Choose Predefined Service, select a predefined service from the Service field.

30 | Chapter 3. Content Filtering and Firewall Rules Wireless Cable Modem Gateway CG2003D User Manual Considerations for Port Forwarding• If the IP address of the local server PC is assigned by DHCP, it may change when the PC is rebooted. To avoid this, you can assign a static IP address to your server outside the range that is assigned by DHCP, but in the same subnet as the rest of your LAN. By default, the IP addresses in the range of 192.168.0.2 through 192.168.0.9 are reserved for this purpose.• Local PCs access the local server using the PCs’ local LAN address (192.168.0.XXX, by default). Attempts by local PCs to access the server using the external WAN IP address will fail.Remember that allowing inbound services opens holes in your firewall. Only enable those ports that are necessary for your network.Set up Port TriggeringPort triggering is an advanced feature that can be used to easily enable gaming and other Internet applications that would otherwise be blocked by the firewall. Using this feature requires that you know the port numbers that are used by the application.Once set up, port triggering operation is as follows:1. A PC makes an outgoing connection using a port number defined in the Port Triggering table.2. The gateway records this connection, opens the incoming port or ports associated with this entry in the Port Triggering List, and associates them with the PC.3. The remote system receives the PCs request, and responds using a different port number.4. The gateway matches the response to the previous request, and forwards the response to the PC. (Without port triggering, this response would be treated as a new connection request rather than a response. As such, it would be handled in accordance with the port forwarding rules.)Note: Only one PC can use a port triggering application at any time. After a PC has finished using a port triggering application, there is a short time-out period before the application can be used by another PC.
Chapter 3. Content Filtering and Firewall Rules | 31Wireless Cable Modem Gateway CG2003D User Manual To set up port triggering:1. Select Advanced > Port Triggering. The Port Triggering screen displays.2. For each port trigger that you would like to enable, enter the following settings in the Port Trigger List and enable the port trigger:• Trigger Range. The trigger range consists of the range of outgoing ports to be monitored to trigger the incoming port forwarding rule:- Start Port. Enter the start port for the trigger range.- End Port. Enter the start port for the trigger range.• Target Range. The target range consists of the range of incoming ports to be opened when triggered:- Start Port. Enter the start port for the target range.- End Port. Enter the start port for the target range.• Protocol. Select the protocol for the ports,:- TCP. Select TCP only.- UDP. Select UDP only.- Both. Select both TCP and UDP.• Select the Enable check box to activate the port trigger.3. Perform one of the following actions:• Click Apply to save your settings and activate the port triggers that you have enabled in step 2.• Click Delete to remove a port trigger that you can select by clicking the radio box next to the port trigger that you want to delete.• Click Reset to return all trigger and target ranges to their default values of zero.
