AC1600 WiFi Cable Modem Router 7. The following table describes the protection and ping options on the WAN Setup page. Field Description Disable IPv4 Firewall Protection IPv4 firewall protection can secure your network against malicious packets. To disable IPv4 firewall protection, select the Disable IPv4 Firewall Protection check box. By default, IPv4 firewall protection is enabled. NETGEAR recommends that you leave the firewall enabled to protect your network. Disable Port Scan and DoS Protection Port scan and DoS protection can protect your LAN against denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, Teardrop Attack, UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. However, when port scan and DoS protection are enabled, some Apple computers might not be able to connect to the Internet. By default, port scan and DoS protection are disabled. To enable port scan and DoS protection, clear the Disable Port Scan and DoS Protection check box. Note: Enabling port scan and DoS protection might affect the performance of the modem router. Respond to Ping on Internet Port By default, this check box is cleared to prevent the modem router from responding to a ping from the Internet. To enable the modem router to respond to a ping, select the Respond to Ping on Internet Port check box. Note: When you allow the modem router to respond to a ping from the Internet, the modem router could be discovered by anyone and in that way become vulnerable to attacks. For optimum security, keep this check box cleared. 8. If you changed the settings, click the Apply button. Your settings are saved. Set 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 modem router can detect some of these applications and function correctly with them but other applications 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 that is designated as the default DMZ server loses firewall protection from exploits on the Internet. Once compromised, the DMZ server computer attacks other computers on your network.
