Section 3 - Conguration
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.
Check the enable UPnP box to allow the router to be detected by devices with
UPnP enabled. From your Windows computer the router will be displayed in your
network settings. Double-click the icon to access the web-based conguration
utility.
This feature also will allow clients on your network to automatically open ports
on the router so you do not have to manually open them (i.e., virtual server/port forwarding). If you disable UPnP, you may have
to manually open ports for certain applications and games in the Virtual Server or Port Forwarding sections. Please refer to the
application manufacturer for a list of ports needed.
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.
Allows application 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 o.
