To complement the powerful firewall technologies incorporated 

into the router product, you can use the comprehensive set of 

security management features to regulate the types of Internet 

access permitted. You may set up time-based access policies 

and block objectionable websites from children, or even set up 

packet filtering rules to control the transmission of TCP, UDP 

packets for different ports. 

More than just a “NAT” firewall, there is a powerful Stateful Packet 

Inspection (SPI) firewall  in the router.  Stateful inspection 

compares certain key parts of the packet to a database of 

trusted information.  SPI Firewall is unlike the normal firewall that 

only checks the headers of the packets, it also scrutinizes the 

contents of the packets, ensuring the integrity of the packets. 

As the router handles the incoming and outgoing traffic of data 

packets between the internal and external network, it checks 

whether incoming WAN packets are legitimate replies to requests 

from LAN users before allowing them to pass into the LAN. This 

checking provides effective firewall protection because rogue 

Internet packets will be automatically discarded. 

The router uses a private key encryption known as Wired 

Equivalent Privacy protocol with key lengths of either 64-bit or 128-

bit, so that data communication in your wireless network can be 

protected. Additionally, with WPA-PSK, the router provides home 

and SOHO users with the highest-level security.
