Table 35. Attack Checks screen settings for IPv4

Setting	Description
WAN Security Checks
Respond to Ping on	Select the Respond to Ping on Internet Ports check box to enable the wireless
Internet Ports	VPN firewall to respond to a ping from the Internet to its IPv4 address. A ping can be
	used as a diagnostic tool. Keep this check box cleared unless you have a specific
	reason to enable the wireless VPN firewall to respond to a ping from the Internet.
Enable Stealth Mode	Select the Enable Stealth Mode check box (which is the default setting) to prevent
	the wireless VPN firewall from responding to port scans from the WAN, thus making
	it less susceptible to discovery and attacks.
Block TCP flood	Select the Block TCP flood check box (which is the default setting) to enable the
	wireless VPN firewall to drop all invalid TCP packets and to protect the wireless VPN
	firewall from a SYN flood attack.
	A SYN flood is a form of denial of service attack in which an attacker sends a
	succession of SYN (synchronize) requests to a target system. When the system
	responds, the attacker does not complete the connections, thus leaving the
	connection half open and flooding the server with SYN messages. No legitimate
	connections can then be made.
