Description

Stateful Packet

 

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, H.323 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.
