Disable IGMP Proxying. IGMP proxying allows a computer on the local area network
(LAN) to receive the multicast traffic it is interested in from the Internet. If you do not
need this feature, you can select this check box to disable it.

MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Change the
MTU only if you are sure that it is necessary for your ISP connection. See

NAT Filtering. Network Address Translation (NAT) determines how the router
processes inbound traffic. Secured NAT protects computers on the LAN from attacks
from the Internet but might prevent some Internet games, point-to-point applications,
or multimedia applications from working. Open NAT provides a much less secured
firewall but allows almost all Internet applications to work.

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.

WARNING:
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall and
is exposed to exploits from the Internet. If compromised, the DMZ
server computer can be used to attack other computers on your
network.

The router usually detects and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you configured in the Port
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can specify that the
router forwards the traffic to one computer on your network. This computer is called the
default DMZ server.

To set up a default DMZ server:
1.
Launch a web browser from a computer or wireless device that is connected to the
network.
