DMZ Figure 48 DMZ Screen
If you have a client PC that cannot run an Internet application properly
from behind the firewall, you can open the client up to unrestricted
two-way Internet access. This may be necessary if the NAT feature is
causing problems with an application such as a game or video
conferencing application.
Use this feature on a temporary basis. The computer in the DMZ is not
protected from hacker attacks.
To put a computer in the DMZ, enter the last digits of its LAN IP address in
the Static IP field. Put the IP address (if known) that will be accessing the
DMZ PC into the Public IP field, so that only the computer on the Internet
at this address can access this PC without firewall protection. If the IP
address is not known, or if more than one PC on the Internet will need to
access this PC, then set the Public IP to 0.0.0.0.
Click Apply.
Advanced From the Advanced screen, you can configure:
NAT (Network Address Translation)
