Advanced Settings37 NETGEAR DOCSIS 3.0 N450 Wi-Fi Data GatewayPort BlockingYou can use port blocking to block outbound traffic on specific ports. Outbound traffic 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 rule.Note: The default rule allows any outbound traffic not blocked by rules that you create.To configure port blocking:1. In the main menu, under Advanced, select Port Blocking.2. From the Service list, select the service you want to block. 3. To add a custom service that is not in the list of services, specify these settings in the Add Custom Service table:•Name. A name for the service.•Start Port. The start port for the service.•End Port. The end port for the service.•Protocol. The protocol for the ports:- TCP. TCP only.- UDP. UDP only.- Both. Both TCP and UDP.•Local IP Address.

Port forwarding affects the inbound rules. These rules restrict access from outsiders. By default,

Advanced Settings38NETGEAR DOCSIS 3.0 N450 Wi-Fi Data Gateway the gateway blocks access from outside except for responses to requests from the LAN side. You can use port forwarding to add rules to specify exceptions to the default rule.Because 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. Directing traffic is also known as port forwarding.Some residential broadband ISPs do not allow you to run server processes (such as a web or FTP server) from your location. Your ISP might check for servers and suspend your account if it finds active services at your location. See the ISP’s Acceptable Use policy.Pay attention to the following considerations before configuring port forwarding:•If the DHCP assigns the IP address of the local server computer, the address might change when the computer is rebooted. To keep the address from changing, you can assign a static IP address to your server outside the range that DHCP assigns, but in the same subnet as your LAN. By default, the IP addresses from 192.168.0.2 through 192.168.0.9 are reserved for this purpose.•Local computers must access the local server using the computers’ local LAN address (192.168.0.XXX, by default). Attempts by local computers to access the server using the external WAN IP address fail.•Port forwarding opens holes in your firewall. Enable only ports that are necessary.To configure port forwarding and services for specific inbound traffic:1. In the main menu, under Advanced, select Port Forwarding.2. From the Service list, select the service for which you want to configure port forwarding. 3. To add a custom rule that is not in the list of services, specify these settings in the Add Custom Rules table:•Name. A name for the service.•Start Port. The start port for the service.•End Port. The end port for the service.•Protocol. The protocol for the ports:- TCP. TCP only.- UDP. UDP only.- Both. Both TCP and UDP.•Local IP Address. Complete the local IP address for the computer that is using the service.4. Perform one of these actions:•Click Add. The Active Forwarding Rules table displays the list of forwarded ports.

Advanced Settings39 NETGEAR DOCSIS 3.0 N450 Wi-Fi Data Gateway•To delete a service, select the radio button in the Active Forwarding Rules table for the service that you want to delete, and click Delete.•To reset the selection in the Service list and to clear all the fields in the Add Custom Rules, click Reset.Port TriggeringPort triggering is an advanced feature that you can use to allow gaming and other Internet applications that the firewall would otherwise block. You must know the port numbers the application uses. Port triggering operates as follows:1. A computer 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 computer.3. The remote system receives the computer’s request, and responds using a different port number.4. The gateway matches the response to the previous request, and forwards the response to the computer. (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 computer at a time can use port triggering. After a computer finishes using a port triggering application, there is a short time-out period before another computer can use the application.To configure port triggering:1. In the main menu, under Advanced, select Port Triggering.

Advanced Settings40NETGEAR DOCSIS 3.0 N450 Wi-Fi Data Gateway 2. For each port trigger, enter the settings in the Port Triggering List:•Trigger Range. To specify the range of outgoing ports that are monitored to trigger the incoming port forwarding rule, enter the start port and end port.•Target Range. To specify the range of incoming ports that are opened when triggered, enter the start port and end port.•Protocol. Select the protocol for the ports:- TCP. Select TCP only. - UDP. Select UDP only. - Both. Select both TCP and UDP. 3. Select the Enable check box for the port trigger.4. Perform one of the following actions:•Click Apply to save your settings and activate the port triggers.•To remove a port trigger, select its radio button, and click Delete.•To return all trigger and target ranges to zero, click Reset.DMZ HostYou can use the DMZ Host screen to set up a default DMZ computer. Specifying a default DMZ computer allows you to set up a computer that is available to anyone on the Internet for services that you have not defined. To minimize security risks, set up the DMZ host only if you are willing to risk open access. If you do not define a DMZ host, the gateway discards any undefined service requests.To set up a DMZ host:1. In the main menu, under Advanced, select DMZ Host. 2. Select the Respond to Ping on WAN Port check box.When you select this check box, the gateway responds to a ping request instead of the DMZ computer.

Advanced Settings41 NETGEAR DOCSIS 3.0 N450 Wi-Fi Data GatewayFor example, some systems tracking the performance of the broadband connections in terms of latency and packet loss need the gateway to reply to ping requests.3. Type the last digits of the IP address in the DMZ Address field.The DMZ host feature is disabled when the last digit is zero.4. Click Apply.LAN IP SetupThe LAN IP screen allows you to configure LAN services such as the IP address of the gateway and DHCP. The TCP/IP and DHCP default values work fine in most cases. Note: If you disable the DHCP server, assign to your computer a static IP address to reconnect to the gateway and enable the DHCP server again.To configure LAN IP settings:1. In the main menu, under Advanced, select LAN IP. 2. Specify these settings:•LAN IP Address. The factory default setting is 192.168.0.1.•Subnet Mask. The network number portion of an IP address. Unless you are implementing subnetting, use 255.255.255.0 as the subnet mask.•DHCP Server. The Yes radio button is selected by default so the gateway acts as a DHCP server, providing the TCP/IP configuration for all the computers connected to it. If you plan to assign IP addresses manually, or you have another DHCP server on your network, select the No radio button.•Starting IP Address and Ending IP Address. These fields specify the range in the IP address pool. •Max Users. The maximum number of users on the network.

From the Auto column corresponding to the port you want to disable, clear the checkbox.3. Click Apply.Configure Universal Plug and Play (UPnP)Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. With UPnP, you can specify the following:•Advertisement period. Specifies how often the gateway broadcasts its UPnP information. The default is 30 minutes. Lower numbers ensure that control points have current device status at the expense of more network traffic. Larger numbers compromise the freshness of the device status but can significantly reduce network traffic.•Advertisement time to live. The time to live for the advertisement, measured in hops (steps) for each UPnP packet that is sent. Hops are the steps a packet takes between routers. The number of hops can range from 1 to 255. The default value for the advertisement time to live is four hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, you might need to increase this value slightly.To configure UPnP:1. In the main menu, under Advanced, select UPnP. 2. Select the Turn UPnP On check box.

Advanced Settings44NETGEAR DOCSIS 3.0 N450 Wi-Fi Data Gateway By default, this check box is cleared.
