The following settings display:
•
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, and many
others. Select this check box only in special circumstances.
•
Default DMZ Server
. This feature is sometimes helpful when you are playing online
games or videoconferencing, but it makes the firewall security less effective. See
•
Respond to Ping on Internet Port
. This feature allows your router to be discovered.
Use this feature only as a diagnostic tool or if 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. Change the
MTU only if you are sure that it is necessary for your ISP connection. See
40.
•
NAT Filtering
. Network Address Translation (NAT) determines how the router
processes inbound traffic. Secured NAT protects computers on the LAN from attacks
from the Internet, but might prevent some Internet games, point-to-point applications,
or multimedia applications from working. Open NAT provides a much less secured
firewall, but allows almost all Internet applications to work.
