Security Features
Internet Access Policies: Time-based Management, URL
filtering, Packet filtering
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.
Stateful Packet Inspection (SPI) firewall
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.
Built-in “NAT” firewall
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.
WPA-PSK and 64/128-bit WEP encryption support for
wireless security
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.
