Virtual Server based on IP Forwarding

If you have subscribed to a range of IP addresses from your ISP, you may also define Virtual Servers based on IP Forwarding. This type of Virtual Server forwards all Internet requests, regardless of the TCP port of the application, to a computer in the private network. Refer to Figure 3.3.1-2.

Virtual Server based on

IP Forwarding

Figure 3.3.1-2 shows two Virtual Servers based on IP Forwarding. One maps the public IP 203.120.12.11 to private IP 192.168.168.10, and the other maps the public IP 203.120.12.12 to private IP 192.168.168.20.

Defining Virtual Server based on De-Militarized Zone (DMZ)

Due to the nature of Network Address Translator (NAT), the subnet behind the NAT cannot be reached from the Internet. If you know the TCP/UDP port of an application, such as HTTP, you can easily define a Virtual Server based on Port Forwarding behind the NAT to support a Web Server in your private subnet. However, if you are uncertain on the TCP/UDP port used by an application (certain Internet games), or an application utilizes varying TCP/UDP port, you may define a DMZ host of which the NetPassage 15 will direct all the unresolved Internet requests to.

For example, if the WAN interface of NetPassage 15 has been assigned an IP address of 203.120.12.20 and you have defined a DMZ host with IP address of 192.168.168.10, all the unresolved Internet requests to 203.120.12.20 will be forwarded to 192.168.168.10, regardless of the TCP/UDP port.
