DMZ

(shown in Figure 4-39).The DMZ host feature allows one local host to be exposed to the 
Internet for a special-purpose service such as Internet gaming or videoconferencing. DMZ host 
forwards all the ports at the same time. Any PC whose port is being forwarded must have its 
DHCP client function disabled and should have a new static IP Address assigned to it because 
its IP Address may be changed when using the DHCP function.
