•
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 Set up a default DMZ server on page 83.
•
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, 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
Change the MTU size on page 48.
•
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.
•
Disable SIP ALG. The application-level gateway (ALG) for the Session Initiation
Protocol (SIP) is enabled by default for enhanced address and port translation.
However, some types of VoIP and video traffic might not work well when the SIP
