The following settings display:
• Disable IPv4 Firewall Protection. NETGEAR
recommends that you leave this check
box empty so that the firewall protects your modem router.
• Disable Port Scan and DoS Protection. DoS prote
ction protects your LAN against
denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, and many
others. Select this check box only in special circumstances.
• Default DMZ Server.
This feature is disabled by default. It is sometimes helpful when
you are playing online games or videoconferencing, but it makes the firewall security

Set Up a Default DMZ Server on page 41.
• Respond to Ping on Internet Port. This fea
