DMZ If you have a client PC that cannot run an Internet application properly

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.
Figure 58 DMZ Screen
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:
1 Check the Enable 1-to-1 NAT checkbox.
2 Enter the last digits of the LAN IP address in the Client PC IP Address field.
Enter the IP address (if known) that will be accessing the DMZ PC into the
Public IP Address field, so that only the computer on the Internet at this
address can access the DMZ PC without firewall protection. If the IP
address is not known, or if more than one PC on the Internet will need to
access the DMZ PC, then set the Public IP Address to 0.0.0.0.
3 Click Apply.
