•Disable Port Scan and DoS Protection. DoS protection protects 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. By default, this check box is cleared.
•Default DMZ Server. A demilitarized zone (DMZ) server can be helpful when you play online games and use videoconferencing. Be careful when you use this feature because it makes the firewall security less effective. For more information, see Default DMZ Server on page 44.
•Respond to Ping on Internet Port. If you want the router to respond to a ping from the Internet, select this check box. By default, this check box is cleared. Use this feature only as a diagnostic tool because it allows your 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. This change is rarely required. Do not make this change unless you are sure that it is necessary for your ISP connection. For more information, see Change the MTU Size on page 45.
