Reference Manual for the ProSafe VPN Firewall FVS318v3 The Default DMZ Server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The firewall is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC's IP address is entered as the Default DMZ Server. Note: For security, NETGEAR strongly recommends that you avoid using the Default DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network. To assign a computer or server to be a Default DMZ server: 1. Click Default DMZ Server. 2. Type the IP address for that server. 3. Click Apply. Note: In this application, the use of the term "DMZ" has become common, although it is a misnomer. In traditional firewalls, a DMZ is actually a separate physical network port. A true DMZ port is for connecting servers that require greater access from the outside, and will therefore be provided with a different level of security by the firewall. A better term for our application is Exposed Host. Respond to Ping on Internet WAN Port If you want the firewall to respond to a ping from the Internet, click the Respond to Ping on Internet WAN Port check box. This should only be used as a diagnostic tool, since it allows your firewall to be discovered. Don't check this box unless you have a specific reason to do so.

The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The firewall is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC’s IP address
is entered as the Default DMZ Server.
To assign a computer or server to be a Default DMZ server:
1.
Click
Default DMZ Server
.
2.
Type the IP address for that server.
3.
Click
Apply
.
Respond to Ping on Internet WAN Port
If you want the firewall to respond to a ping from the Internet, click the
Respond to Ping on
Internet WAN Port
check box. This should only be used as a diagnostic tool, since it allows your
firewall to be discovered. Don't check this box unless you have a specific reason to do so.
Note:
For security, NETGEAR strongly recommends that you avoid using the Default
DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses
much of the protection of the firewall, and is exposed to many exploits from the Internet.
If compromised, the computer can be used to attack your network.
Note:
In this application, the use of the term “DMZ” has become common, although it is
a misnomer. In traditional firewalls, a DMZ is actually a separate physical network port.
A true DMZ port is for connecting servers that require greater access from the outside,
and will therefore be provided with a different level of security by the firewall. A better
term for our application is Exposed Host.
