SPI (Stateful Packet Inspection), also known as dynamic packet ltering, helps
to prevent cyber attacks by tracking more state per session. It validates that
the trac passing through the session conforms to the protocol.
Enable this feature to protect your network from certain kinds of “spoong”
attacks.
If an application has trouble working from behind the router, you can expose
one computer to the Internet and run the application on that computer.
Note: Placing a computer in the DMZ may expose that computer to a variety
of security risks. Use of this option is only recommended as a last resort.
Specify the IP address of the computer on the LAN that you want to have
unrestricted Internet communication. If this computer obtains its IP address
automatically using DHCP, be sure to make a static reservation on the Setup
> Network Settings page so that the IP address of the DMZ machine does
not change.
Allows multiple machines on the LAN to connect to their corporate network
using PPTP protocol.
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 o. Please check with the system administrator of your corporate
network whether your VPN client supports
NAT traversal.

A rewall protects your network from the outside world. The DIR-655 oers a rewall type functionality. The Stateful Packet Inpection (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.
