NAT Filtering. Network Address Translation (NAT) determines how the router
processes inbound traffic:
processes inbound traffic:
-
Secured NAT provides a secured firewall to protect the computers on the LAN
from attacks from the Internet, but might prevent some Internet games,
point-to-point applications, or multimedia applications from functioning. By default,
the Secured radio button is selected.

Open NAT provides a much less secured firewall, but allows almost all Internet
applications to function.

Disable SIP ALG. Some Voice over IP (VoIP) applications do not function well with
the Session Initiation Protocol (SIP) Application Layer Gateway (ALG). Selecting the
check box to turn off the SIP ALG might enable connected VoIP devices to create and
accept a VoIP call through the router. By default, this check box is cleared.

Disable IGMP Proxying. IGMP proxying allows computers on the LAN to receive the
multicast traffic they are subscribed to from the Internet. By default, this check box is
selected, and the IGMP proxy is disabled, preventing multicast traffic from the Internet
to the LAN. Clear the Disable IGMP Proxying check box to allow multicast traffic

Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The router is programmed to recognize some of these applications and to work
correctly with them, but other applications might not function well. In some cases, one local
computer can run the application correctly if the IP address for that computer is entered as
the default DMZ server.
