Using the Advanced Gateway Setup DMZ Host Option
The
DMZ
(demilitarized zone)
Host
option allows you configure a network device as a
host visible to the Internet. The DMZ host receives the WAN traffic that NAT is unable to
translate. This can be used when applications do not work with port triggers.
Note:
Because DMZ host IP addresses are exposed to the Internet, it is strongly advised
a protection mechanism is used to avoid external attacks.
