Select Advanced > Setup > WAN Setup:
The following settings are available:
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. This
should be disabled only in special circumstances.
Default DMZ Server. This feature is sometimes helpful when you are playing online
•
games or videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See the following section,
more details.
Respond to Ping on Internet Port. If you want the router to respond to a ping from
•
the Internet, select this check box. Use this setting 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.
Disable IGMP Proxying. IGMP proxying allows a computer on the local area network
•
(LAN) to receive the multicast traffic it is interested in from the Internet. If you do not
need this feature, you can select this check box to disable it.
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 is rarely required, and should not be
done unless you are sure it is necessary for your ISP connection. See
on page 35.
MTU Size
NAT Filtering. Network Address Translation (NAT) determines how the router
•
processes inbound traffic. 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.
