Setting Description
Disable Port Scan and DOS
Protection This check box is usually clear so that the firewall protects your LAN
against port scans and denial of service (DOS) attacks. This check box
should be selected only in special circumstances.
Default DMZ Server This feature is sometimes helpful when you are using some online
games and videoconferencing. Be careful when using this feature
because it makes the firewall security less effective. See
“Setting Up a
Default DMZ Server” on page 5-3 .
Respond to Pin on Internet
WAN Port If you want the router to respond to a ping from the Internet, select this
check box. This should be used only as a diagnostic tool, since it allows
your router to be discovered. Do not select this check box unless you
have a specific reason to do so.
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.
