SPI (Stateful Packet Inspection):
The Router's Firewall uses Stateful Packet
Inspection to maintain connection information that passes through the firewall. It will
inspect all packets based on the established connection, prior to passing the
packets for processing through a higher protocol layer.

DoS (Denial of Service):
Protect internal networks from Internet attacks, such as
SYN Flooding, Smurf, LAND, Ping of Death, IP Spoofing and reassembly attacks.
z
Block WAN Request:
This feature is designed to prevent attacks through the
Internet. When it is enabled, the Router will drop both the unaccepted TCP request
and ICMP packets from the WAN side. The hacker will not find the Router by pinging
the WAN IP address. If DMZ is enabled, this function will be disabled.
z
Remote Management:
This Router supports remote management. If you want to
manage this Router through the WAN connection, you have to 'Enable' this option.
Users can select port 80 or port 8080 for remote management.
z
Multicast Pass Through:
IP Multicasting occurs when a single data transmission is
sent to multiple recipients at the same time. Using this feature, the Router allows IP
multicast packets to be forwarded to the appropriate computers.
z
MTU (Maximum Transmission Unit):
This feature specifies the largest packet size
permitted for network transmission. It is recommended that you enable this feature,
and the default of MTU size is 1500 bytes.
