[. . . ] In this case, you can use a commercial Dynamic DNS service, which allows you to register your domain to their IP address, and forwards traffic directed at your domain to your frequently changing IP address. Note: If your ISP assigns a private WAN IP address (such as 192. 168. x. x or 10. x. x. x), the Dynamic DNS service will not work because private addresses are not routed on the Internet. Your router contains a client that can connect to the Dynamic DNS service provided by DynDNS. org. You must first visit their website at www. dyndns. org and obtain an account and host name, which you specify in the router. Then, whenever your ISP-assigned IP address changes, your 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 router at hostname. dyndns. org. The Dynamic DNS screen displays. Figure 4-3 4-6 v1. 3, February 2009 Customizing Your Network Settings NETGEAR Wireless-N Router WNR2000 User Manual To configure for a Dynamic DNS service: 1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. Enter the host name (or domain name) that your Dynamic DNS service provider gave you. This is the name that you use to log in to your account, not your host name. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use Wildcards check box to activate this feature. For example, the wildcard feature causes *. yourhost. dyndns. org to be aliased to the same IP address as yourhost. dyndns. org. Click Apply to save your configuration.

The WAN Setup screen displays. Figure 4-4 Disabling the SPI Firewall The Stateful Packet Inspection (SPI) firewall protects your network and computers against attacks and intrusions. A stateful packet firewall carefully inspects incoming traffic packets, looking for known exploits such as malformed, oversized, or out-of-sequence packets. The firewall should be disabled only in special circumstances, such as when you are troubleshooting application issues. Setting Up a Default DMZ Server 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 router is programmed to recognize some of these applications and to work correctly with 4-8 v1. 3, February 2009 Customizing Your Network Settings NETGEAR Wireless-N Router WNR2000 User Manual them, but there are other applications that might not function well. In some cases, one local computer can run the application correctly if that computer's IP address is entered as the default DMZ server. A computer 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. Incoming traffic from the Internet is usually discarded by the router 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.
