CONFIGURING THE BARRICADE

Parameter	Defaults	Description
Stateful Packet	Enabled	This option allows you to select different
Inspection		application types that are using dynamic port
		numbers. If you wish to use Stateful Packet
		Inspection (SPI) for blocking packets, click on the
		Yes radio button in the “Enable SPI and Anti-DoS
		firewall protection” field and then check the
		inspection type that you need, such as Packet
		Fragmentation, TCP Connection, UDP Session,
		FTP Service and TFTP Service.
		It is called a “stateful” packet inspection because it
		examines the contents of the packet to determine
		the state of the communication; i.e., it ensures that
		the stated destination computer has previously
		requested the current communication. This is a
		way of ensuring that all communications are
		initiated by the recipient computer and are taking
		place only with sources that are known and trusted
		from previous interactions. In addition to being
		more rigorous in their inspection of packets,
		stateful inspection firewalls also close off ports
		until a connection to the specific port is requested.
		When particular types of traffic are checked, only
		the particular type of traffic initiated from the
		internal LAN will be allowed. For example, if the
		user only checks FTP Service in the Stateful Packet
		Inspection section, all incoming traffic will be
		blocked except for FTP connections initiated from
		the local LAN.
