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

network.
The router detects and discards incoming traffic from the Internet that is not a response to 
one of your local computers or a service that you have configured in the Port...
