4.6 Advanced Security
DeMilitarized Zone (DMZ)
You may configure a single computer to be logically “outside” of the router’s
protective firewall. A computer in the DMZ will have unrestricted 2-way commu-
nications with the Internet (WAN). You should consider this option only when
your networked application or service cannot be accommodated through the
router’s Distributed Servers (see Chapter 5) or Popular Applications (see Sec-
tion 4.4) settings.
Note: If you enable this option, you should define the Secure Packet Inspection
(SPI) filters to protect your DMZ computer from unauthorized access or tamper-
ing.
To logically place a computer in the router’s DMZ:
1. Enter the IP address of the target computer. The first three numbers of the
IP address (default is 192.168.123) are automatically inserted for you.
2. Click the Apply New Advanced Security Settings button to save your
changes.
WARNING: Exercise caution before making changes in this section. Improper
settings could seriously compromise the security of your router and your net-
work.
