or multimedia applications from working. Open NAT provides a much less secured
firewall, but allows almost all Internet applications to work.
Disable SIP ALG. Some voice or video communication applications do not work well
with SIP ALG. Disabling SIP ALG might help your voice or video applications to create
or accept a call through the router.

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 page. Instead of discarding this traffic, the router can forward 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 an Internet browser from a computer or wireless device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
