[. . . ] Registration is required before you can use our telephone support service. Setup documentation is available on the CD, on the support website, and on the documentation website. When the wireless router is connected to the Internet, click the Knowledge Base or the Documentation link under Web Support on the main menu to view support information. Trademarks NETGEAR and the NETGEAR logo are registered trademarks, and RangeMax and Smart Wizard are trademarks of NETGEAR. [. . . ] 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 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. warning: DMZ servers pose a security risk. 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. This computer is called the default DMZ server. The WAN Setup screen lets you configure a default DMZ server. In the Default DMZ Server fields, enter the IP address for that computer or server. Responding to a Ping on the Internet (WAN) Port If you want the router to respond to a ping from the Internet, select the Respond to Ping on Internet Port check box. This should be used only as a diagnostic tool, since it allows your router to be discovered by Internet scanners. Do not select this check box unless you have a specific reason to do so, such as when troubleshooting your connection. 0, January 2009 4-7 N150 Wireless Router WNR1000 User Manual Setting the MTU Size The normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE connections, or 1450 for PPTP connections. For some ISPs, you might need to reduce the MTU size, but this is rarely required and should not be done unless you are sure it is necessary for your ISP connection. For more information, see “Changing the MTU Size” on page 5-15. In the MTU Size field, enter a new size between 64 and 1500. Secured NAT provides a secured firewall to protect the computers on the LAN from attacks from the Internet, but might prevent some Internet games, point-to-point applications, or multimedia applications from functioning. Open NAT provides a much less secured firewall, but allows almost all Internet applications to function. For more information about NAT, see “How Your Computer Accesses a Remote Computer through Your Router” on page 5-2. In the NAT Filtering area, select either the Secured or the Open radio button. [. . . ] Restoring the Default Configuration and Password This section explains how to restore the factory default configuration settings that reset the router’s user name to admin, the password to password, and the IP address to 192. You can erase the current configuration and restore factory defaults in two ways: • • Use the Erase function of the router. To use the Erase function, see “Erasing the Configuration” on page 6-7. Use the restore factory settings button on the rear panel of the router. [. . . ]
