Setting Up A Default Dmz Server; Responding To A Ping On The Internet (Wan) Port; Setting The Mtu Size - NETGEAR WGR614v11 User Manual

Setting 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 there are other applications that might not function well. In some
cases, one local computer can run the application correctly if that computer's IP address 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.
Incoming traffic from the Internet is usually discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have it
forwarded to one computer on your network. This computer is called the default DMZ server.
The WAN Setup screen lets you configure a default DMZ server.
To assign a computer or server to be a default DMZ server:
1. Select the Default DMZ Server check box.
2. In the Default DMZ Server fields, enter the IP address for that computer or server.
3. Click Apply.

Responding to a Ping on the Internet (WAN) Port

If you want the router to respond to a ping from the Internet, select the Respond to Ping on
Internet Port check box. This should be used only as a diagnostic tool, since it allows your
router to be discovered by Internet scanners. Do not select this check box unless you have a
specific reason to do so, such as when troubleshooting your connection.

Setting the MTU Size

The normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE
connections, or 1450 for PPTP connections. For some ISPs, you might need to reduce the
MTU size, but this is rarely required and should not be done unless you are sure it is
necessary for your ISP connection. For more information, see
page 70.
