SPI (Stateful Packet Inspection)
Enables the packet automatic
authentication detection technology.
The firewall operates mainly at the
network layer. By running the dynamic
authentication for each connection, it
will also perform an alarming function
for application procedure. Meanwhile,
the packet authentication firewall may
decline the connections that use non-
standard communication protocol.
DoS (Denial of Service)
Prevents DoS attacks such as SYN
Flooding, Smurf, LAND, Ping of Death,
IP Spoofing and so on.
Block WAN Request
When enabled, shuts down outbound
ICMP and abnormal packet responses
in connection. Default value is
enabled, which prevents users from
pinging the WAN IP from outside the
network.
Remote Management
Must be enabled to enter the device’s
Web-based UI remotely. A valid
external IP address (WAN IP) for the
device should be filled in and the
modifiable default control port should
be adjusted (the default is set to 80,
modifiable).
HTTPS Multicast Pass Through
HTTPS is more secure. This feature
allows user to turn on HTTPS.
There are many audio and visual
streaming media on the network.
Broadcasting may allow the client end
to receive this type of packet message
format. This feature is off by default.

This feature allows users to enable/
disable UPnP.
