Configure the Firewall 
 
Configure SPI Firewall 
(Available in Wireless Routing Client and Gateway modes) 
Stateful Packet Inspection (SPI) thwarts common hacker attacks like IP 
Spoofing, Port Scanning, Ping of Death, and SynFlood by comparing 
certain key parts of the packet to a database of trusted information 
before allowing it through. 
 
 
 
NOTE 
Firewall security rules should be planned carefully as incorrect 
configuration may cause improper network function.
