2.5.5 Applications Command
1. Set up DMZ function.
Command
Parameter Description
Gateway(config)# applications
dmz
Enable DMZ function. DMZ stands for
“Demilitarized Zone”. It is an IP address
on the private network of the Residential
Gateway. But it is exposed to the Internet
for special-purpose services. So a host on
the private network can be assigned the
IP address of the DMZ to provide services
to the hosts on the Internet. The network
administrator should be cautious of
adopting DMZ. If a host is on DMZ, it is
not protected by the firewall. And the
Residential Gateway will open all ports to
expose DMZ to the Internet. This may
expose the local network to a variety of
security risk.
