Table 5-1. WAN Setup Settings

Setting	Description
Disable Port Scan and DOS	This check box is usually clear so that the firewall protects your LAN
Protection	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	If you want the router to respond to a ping from the Internet, select this
WAN Port	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.
