SPI (Stateful Packet Inspection, also known as dynamic packet filtering)
helps to prevent cyber attacks by tracking more states per session. It
validates that the traffic passing through the session conforms to the
protocol.
Enable this feature to protect your network from certain kinds of
“spoofing” attacks, where the attackers disguise their origin.
Specify the IP address of the computer on the LAN that you want to have
unrestricted Internet communication. If this computer obtains it’s IP
address automatically using DHCP, be sure to make a static reservation

Firewall Settings
A firewall protects your network from the outside world. The DIR-862L offers a firewall type functionality. The SPI feature helps
prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications.
If you choose to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the
chosen computer completely to the outside world.
DIR-862L
Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec through
NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network,
try turning this ALG off. Please check with the system administrator of your corporate network whether your VPN client supports
NAT traversal.
Allows applications that uses Real Time Streaming Protocol to receive streaming media from the Internet. QuickTime and Real Player
are some of the common applications using this protocol.
Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have
the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are
having trouble making VoIP calls, try turning this ALG off.
