NETGEAR genie Advanced Home24C3000 WiFi Cable Modem Router Attack, UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This setting should be disabled only in special circumstances. •Default DMZ Server. This feature is sometimes helpful when you are playing online games or videoconferencing. Be careful when using this feature, it makes the firewall security less effective. The default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The gateway is programmed to recognize some of these applications and to work correctly with them, but some applications do not function well. In some cases, one local computer can run the application correctly if the IP address of that computer is entered as the default DMZ server.•Respond to Ping on Internet Port. If you want the modem router to respond to a ping from the Internet, select this check box. Use this feature only as a diagnostic tool because it also allows your modem router to be discovered. Do not select this check box unless you have a specific reason.•MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might need to reduce the MTU. Reduce the MTU only if you are sure that it is necessary for your ISP connection.•Disable SIP/ALG. The Session Initiation Protocol (SIP) Application Level Gateway (ALG) is disabled by default which is useful when running certain applications. To enable SIP/ALG and optimize VoIP phone calls that use the SIP, uncheck the check box.The default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The modem router is programmed to recognize some of these applications and to work correctly with them, but some applications do not function well. In some cases, one local computer can run the application correctly if the IP address of that computer is entered as the default DMZ server.WARNING:DMZ servers pose a security risk. A computer that is designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network.The modem router discards incoming traffic from the Internet unless the traffic is a response to one of your local computers or a service that you have configured in the Port Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the default DMZ server.To set up a default DMZ server: 1. On the WAN Setup screen, select the Default DMZ Server check box.2. Type the IP address.
NETGEAR genie Advanced Home25 C3000 WiFi Cable Modem Router3. Click the Apply button.LAN SetupThe LAN Setup screen allows you to configure LAN services such as the IP address of the gateway and DHCP.

Specify the start of the range for the pool of IP addresses in the same subnet as the modem router.•Ending IP Address. Specify the end of the range for the pool of IP addresses in the same subnet as the modem router.Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer receives the same IP address each time it accesses the DHCP server of the modem router. Assign reserved IP addresses to servers that require permanent IP settings. Use the Router as a DHCP ServerBy default, the modem router functions as a DHCP server. This capability allows the modem router to assign IP, DNS server, and default gateway addresses to all computers connected to the LAN that is connected to the modem router. The assigned default gateway address is the LAN address of the modem router. The modem router assigns IP addresses to the attached computers from a pool of addresses that are specified in this screen. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN. For most applications, the default DHCP and TCP/IP settings of the modem router are satisfactory. You can specify the pool of IP addresses that can be assigned by setting the starting IP address and ending IP address. These addresses are part of the same IP address subnet as the LAN that is connected to the modem router. Using the default addressing scheme, you define a range between 192.168.0.2 and 192.168.0.254. You can save part of the range for devices with fixed addresses.The modem router delivers the following parameters to any LAN device that requests DHCP:•An IP address from the range you have defined•Subnet mask•Gateway IP address (the LAN IP address of the modem router)
NETGEAR genie Advanced Home27 C3000 WiFi Cable Modem Router•Primary DNS server (if you entered a primary DNS address in the Internet Setup screen; otherwise, the LAN IP address of the modem router)•Secondary DNS server (if you entered a secondary DNS address in the Internet Setup screen)To use another device on your network as the DHCP server or to configure manually the network settings of all of your computers, clear the Use Router as DHCP Server check box and click the Apply button. Otherwise, leave this check box selected. If this service is not enabled and no other DHCP server is available on your network, set the IP addresses of your computer manually or other devices cannot access the modem router.Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the DHCP server of the modem router.

Click the Apply button.Your changes are saved.Block Services (Port Filtering)Server computers perform services at the request of client computers. For example, web servers serve web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on the Internet sends a request for service to a server computer, a service or port number identifies the requested service. This number displays as the destination port number in the transmitted IP packets. For example, a packet that is sent with the destination port number 80 is an HTTP (web server) request. The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF at http://www.ietf.org/) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 - 65535 by the authors of the application. Although the modem router already holds a list of many service port numbers, you are not limited to these choices. You can often determine port number information by contacting the publisher of the application, by asking user groups or newsgroups, or by searching.The Block Services screen lets you add and block specific Internet services by computers on your network. This capability is called service blocking or port filtering. To add a service for blocking, first determine which port number or range of numbers the application uses. To block services:1.

Click the Add button.The Wireless Card Access List screen displays.8. Click the Apply button.Port Forwarding and Port TriggeringBy default, the modem router blocks inbound traffic from the Internet to your computers except for replies to your outbound traffic. 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 modem router does not recognize their replies.Your modem 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 BasicsWhen a computer on your network accesses a computer on the Internet, your computer sends your modem router a message containing the source and destination address and process information. Before forwarding your message to the remote computer, your modem 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 with the following address and port information. The request message is sent to your modem router.Source address. The IP address of your computer.Source port number. 5678, which is the browser session. Destination address. The IP address of www.example.com, which your computer finds by asking a DNS server.Destination port number. 80, which is the standard port number for a web server process.
Advanced Settings52C3000 WiFi Cable Modem Router 3. Your modem router creates an entry in its internal session table describing this communication session between your computer and the web server at www.example.com. Before sending the web page request message to www.example.com, your modem router stores the original information and then modifies the source information in the request message, performing Network Address Translation (NAT):•The source address is replaced with the public IP address of your modem router. This step is necessary because your computer uses a private IP address that is not globally unique and cannot be used on the Internet.•The source port number is changed to a number that is chosen by the modem router, such as 33333. This step is necessary because two computers could independently be using the same session number.Your modem router then sends this request message through the Internet to the web server at www.example.com.4. The web server at www.example.com composes a return message with the requested web page data. The return message contains the following address and port information. The web server then sends this reply message to your modem router.Source address. The IP address of www.example.com.Source port number. 80, which is the standard port number for a web server process.Destination address. The public IP address of your modem router.Destination port number. 33333.5. Upon receiving the incoming message, your modem router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the modem router then modifies the message to restore the original address information that is replaced by NAT. Your modem router sends this reply message to your computer, which displays the web page from www.example.com. The message now contains the following address and port information.Source address. The IP address of www.example.com.Source port number. 80, which is the standard port number for a web server process.Destination address. The IP address of your computer.Destination port number. 5678, which is the browser session that made the initial request.6. When you finish your browser session, your modem router eventually detects a period of inactivity in the communications. Your modem router then removes the session information from its session table, and incoming traffic is no longer accepted on port number 33333.Port Triggering to Open Incoming PortsIn the preceding example, requests are sent to a remote computer by your modem router from a particular service port number, and replies from the remote computer to your modem router are directed to that port number. If the remote server sends a reply to a different port number, your modem router does not recognize it and discards it. However, some application
Advanced Settings53 C3000 WiFi Cable Modem Routerservers (such as FTP and IRC servers) send replies to multiple port numbers. Using the port triggering function of your modem router, you can tell the modem router to open more incoming ports when a particular outgoing port originates a session.An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination port 6667. The IRC server not only responds to your originating source port, but also sends an “identify” message to your computer on port 113. Using port triggering, you can tell the modem router, “When you initiate a session with destination port 6667, you must allow incoming traffic also on port 113 to reach the originating computer.” Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined:1. You open an IRC client program to start a chat session on your computer. 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your modem router.3. Your modem router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your modem router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server. 4. Noting your port triggering rule and having observed the destination port number of 6667, your modem router creates an additional session entry to send any incoming port 113 traffic to your computer.5. The IRC server sends a return message to your modem router using the NAT-assigned source port (as in the previous example, say port 33333) as the destination port. The IRC server also sends an identify message to your modem router with destination port 113.6. Upon receiving the incoming message to destination port 33333, your modem router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the modem router restores the original address information that is replaced by NAT and sends this reply message to your computer.7. Upon receiving the incoming message to destination port 113, your modem router checks its session table and learns that there is an active session for port 113, associated with your computer. The modem router replaces the destination IP address of the message with the IP address of your computer and forwards the message to your computer.8. When you finish your chat session, your modem router eventually senses a period of inactivity in the communications. The modem router then removes the session information from its session table, and incoming traffic is no longer accepted on ports 33333 or 113.To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that triggers the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.Note: Only one computer at a time can use the triggered application.
Advanced Settings54C3000 WiFi Cable Modem Router Port Forwarding to Permit External Host CommunicationsIn both of the preceding examples, your computer initiates an application session with a server computer on the Internet. However, you need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your modem router ignores any inbound traffic that is not a response to your own outbound traffic. You can configure exceptions to this default rule by using the port forwarding feature. A typical application of port forwarding can be shown by reversing the client-server relationship from the previous web server example. In this case, a browser on a remote computer accesses a web server running on a computer in your local network. Using port forwarding, you can tell the modem router, “When you receive incoming traffic on port 80 (the standard port number for a web server process), forward it to the local computer at 192.168.0.123.” The following sequence shows the effects of the port forwarding rule you have defined:1. The user of a remote computer opens a browser and requests a web page from www.example.com, which resolves to the public IP address of your modem router. The remote computer composes a web page request message with the following destination information: Destination address. The IP address of www.example.com, which is the address of your modem router.Destination port number. 80, which is the standard port number for a web server process.The remote computer then sends this request message through the Internet to your modem router.2. Your modem router receives the request message and looks in its rules table for any rules covering the disposition of incoming port 80 traffic. Your port forwarding rule specifies that incoming port 80 traffic is forwarded to local IP address 192.168.0.123. Therefore, your modem router modifies the destination information in the request message:The destination address is replaced with 192.168.0.123.Your modem router then sends this request message to your local network.3. Your web server at 192.168.0.123 receives the request and composes a return message with the requested web page data. Your web server then sends this reply message to your modem router.4. Your modem router performs Network Address Translation (NAT) on the source IP address, and sends this request message through the Internet to the remote computer, which displays the web page from www.example.com.To configure port forwarding, you need to know which inbound ports the application needs. Usually you can determine this information by contacting the publisher of the application or the relevant user groups and newsgroups.
Advanced Settings55 C3000 WiFi Cable Modem RouterHow Port Forwarding Differs from Port TriggeringThe following points summarize the differences between port forwarding and port triggering:•Port triggering is used by any computer on your network, although only one computer can use it at a time.•Port forwarding is configured for a single computer on your network.•Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity.•Port forwarding is always active and is never triggered.Set Up Port Forwarding to Local ServersUsing the port forwarding feature, you can allow certain types of incoming traffic to reach servers on your local network. For example, you want to make a local web server, FTP server, or game server visible and available to the Internet.Use the Port Forwarding/Port Triggering screen to configure the modem router to forward specific incoming protocols to computers on your local network. In addition to servers for specific applications, you can also specify a default DMZ server to which all other incoming protocols are forwarded.Before starting, you determine which type of service, application, or game you want to provide, and the local IP address of the computer that provides the service. The server computer always must have the same IP address.To set up port forwarding:Tip: To ensure that your server computer always has the same IP address, use the reserved IP address feature of your wireless cable gateway. 1. From the Advanced tab, select Advanced Setup > Port Forwarding/Port Triggering.

Click Edit Service or Delete Service.Application example: Making a Local Web Server PublicIf you host a web server on your local network, you can use port forwarding to allow web requests from anyone on the Internet to reach your web server. To make a local web server public:1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation. In this example, your modem router always gives your web server an IP address of 192.168.0.33.
Advanced Settings58C3000 WiFi Cable Modem Router 2. In the Port Forwarding/Port Triggering screen, configure the modem router to forward the HTTP service to the local address of your web server at 192.168.0.33. HTTP (port 80) is the standard protocol for web servers.3. (Optional) Register a host name with a Dynamic DNS service, and configure your modem router to use the name as described in Dynamic DNS on page 60. To access your web server from the Internet, a remote user must know the IP address that your ISP assigns. However, if you use a Dynamic DNS service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.Set Up Port TriggeringPort triggering is a dynamic extension of port forwarding that is useful in these cases:•More than one local computer needs port forwarding for the same application (but not simultaneously).•An application opens incoming ports that are different from the outgoing port.When port triggering is enabled, the modem router monitors outbound traffic looking for a specified outbound “trigger” port. When the modem router detects outbound traffic on that port, it remembers the IP address of the local computer that sent the data. The modem router then temporarily opens the specified incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering computer. While port forwarding creates a static mapping of a port number or range to a single local computer, port triggering can dynamically open ports to any computer that needs them and can close the ports when they are no longer needed.Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, or remote assistance (a feature in Windows XP), enable Universal Plug and Play (UPnP) according to the instructions in Remote Management on page 61.To set up port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that triggers the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.To set up port triggering: 1. From the Advanced tab, select Advanced Setup > Port Forwarding/Port Triggering.
Advanced Settings59 C3000 WiFi Cable Modem Router2. Select the Port Triggering radio button.3. Clear the Disable Port Triggering check box if it is selected.Note: If the Disable Port Triggering check box is selected after you configure port triggering, port triggering is disabled. However, any port triggering configuration information you added to the modem router is retained even though it is not used.4. In the Port Triggering Time-out field, enter a value up to 9999 minutes. 5. This value controls the inactivity timer for the designated inbound ports. The inbound ports close when the inactivity time expires. This step is required because the modem router cannot be sure when the application has terminated.6. Click the Add Service button.The following screen displays:
Advanced Settings60C3000 WiFi Cable Modem Router 7. In the Service Name field, type a descriptive service name. No spaces are allowed for the service name field.8. In the Service User list, select Any (the default) to allow any computer on the Internet to use this service. Otherwise, select Single address, and enter the IP address of one computer to restrict the service to a particular computer. 9. Select the service type, either TCP or UDP or both (TCP/UDP). If you are not sure, select TCP/UDP.10. In the Triggering Port field, enter the number of the outbound traffic port that causes the inbound ports open. 11. Enter the inbound connection port information in the Connection Type, Starting Port, and Ending Port fields.12. Click the Apply button.The service displays in the Port Triggering Portmap table. Dynamic DNSIf your Internet service provider (ISP) gave you a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you do not know in advance what your IP address is, and the address can change frequently. In this case, you can use a commercial Dynamic DNS service. This type of service lets you register your domain to their IP address and forwards traffic directed at your domain to your frequently changing IP address.If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private addresses are not routed on the Internet.Your modem router contains a client that can connect to the Dynamic DNS service that DynDNS.org provided. First visit their website at http://www.dyndns.org and obtain an account and host name that you configure in the modem router. Then, whenever your ISP-assigned IP address changes, your modem router automatically contacts the Dynamic DNS service provider, logs in to your account, and registers your new IP address. If your host name is hostname, for example, you can reach your modem router at http://hostname.dyndns.org.To set up Dynamic DNS:1. From the Advanced tab, select Advanced Setup > Dynamic DNS.
Advanced Settings61 C3000 WiFi Cable Modem RouterThe following screen displays:2. Register for an account with one of the Dynamic DNS service providers whose names display in the Service Provider list.3. Select the Use a Dynamic DNS Service check box. 4. Select the name of your Dynamic DNS service provider. If your Dynamic DNS service provider is DynDNS.org, for example, select www.dyndns.org.5. Type the host name (or domain name) that your Dynamic DNS service provider gave you.6. Type the user name for your Dynamic DNS account. This name is the name that you use to log in to your account, not your host name.7. Type the password (or key) for your Dynamic DNS account. 8. Click the Apply button.Your configuration is saved.Remote ManagementThe remote management feature lets you access your modem router over the Internet to view or change its settings.Note: Be sure to change the modem router default login password to a secure password. The ideal password contains no dictionary words from any language and contains uppercase and lowercase letters, numbers, and symbols. It can be up to 30 characters. See Set Password on page 41.
Advanced Settings62C3000 WiFi Cable Modem Router To set up remote management:1. From the Advanced tab, select Advanced Setup > Remote Management. 2. Select the Turn Remote Management On check box.3. Under Allow Remote Access By, specify the external IP addresses to be allowed to access the modem router’s remote management.Note: For enhanced security, restrict access to as few external IP addresses as practical.•To allow access from a single IP address on the Internet, select Only This Computer. Enter the IP address that will be allowed access. •To allow access from a range of IP addresses on the Internet, select IP Address Range. To define the allowed range, enter a beginning and ending IP address. •To specify IP addresses, select IP Address List and type in the allowed IP addresses. •To allow access from any IP address on the Internet, select Everyone. 4. Specify the port number for accessing the web management interface.Normal web browser access uses the standard HTTP service port 80. For greater security, enter a custom port number for the remote web management interface. Choose a number from 1024 to 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.5. Click the Apply button.Your changes take effect.6. When you access your modem router from the Internet, type your modem router’s WAN IP address into your browser’s address or location field followed by a colon (:) and the custom port number.
Advanced Settings63 C3000 WiFi Cable Modem RouterFor example, if your external address is 134.177.0.123 and you use port number 8080, enter http://134.177.0.123:8080 in your browser.Universal Plug and PlayUniversal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to 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.Note: If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications such as instant messaging or remote assistance (a feature in Windows XP), enable UPnP.To turn on Universal Plug and Play:1. From the Advanced tab, select Advanced Setup > UPnP. 2. Specify the following settings:Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is enabled. If this check box is not selected, the modem router does not allow any device to control the resources automatically, such as port forwarding (mapping) of the modem router. Advertisement Period. The advertisement period is how often the modem router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of more network traffic. Longer durations can compromise the freshness of the device status, but can significantly reduce network traffic.
Advanced Settings64C3000 WiFi Cable Modem Router Advertisement Time to Live. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is four hops, which are fine for most home networks. If you notice that some devices are not being updated or reached correctly, you should increase this value.UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the modem router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address. 3. Click the Apply button. Your settings are saved.
