DMZ hosting is used to support online gaming and Internet conferencing
services. These programs usually require multiple open ports, making the
network accessible from the Internet. DMZ hosting symbolically places the DMZ
host computer outside of the Gateway’s network. We recommend activating
DMZ hosting only as long as necessary.

Warning : The DMZ Host computer will be vulnerable to computer hackers on
the Internet while in DMZ mode.
6.6 NAT (Network Address Translation)
Selecting NAT in the “Security” screen generates the “NAT” screen. The Gateway’s
basic firewall security is based on NAT. Disabling NAT allows the computers
connected to the Gateway to be accessed by outside parties, and can cause the
loss of Internet connectivity. Do not turn NAT off unless instructed to do so by
Verizon.
