88 CHAPTER 5: CONFIGURING THE ROUTER 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. In the default setting (line 1), Public IP address is set to 0.0.0.0 and it is automatically transformed by default WAN IP. We only allow one DMZ server to be accessed by public IPs (Many to 1 NAT). If you have more than one DMZ server, you have to set a second WAN IP in line 2 and define which IP address of DMZ server you would like to set in the Client PC IP address. For this Router, only 1 to 1 NAT function is allowed. 2 Click Apply.
