Note:

For VCs with single IP, they share the same DMZ and Virtual servers; for VCs with multiple IPs,

each VC can set DMZ and Virtual servers. Furthermore, for VCs with multiple IPs, they can define

the Address Mapping rules; for VCs with single IP, since they have only one IP, there is no need to

individually define the Address Mapping rule.

4.4.3.1. DMZ

Choose “

Advanced Setup

→

NAT

→

DMZ

” in Figure 4-28, you can configure the DMZ host in the

next screen. A DMZ (demilitarized zone) is a host between a private local network and the outside

public network. It prevents outside users from getting direct access to a server that has company

data. Users of the public network outside the company can access to the DMZ host.

Virtual Server

” in Figure 4-28, you can configure the Virtual

Server in the next screen.

The Virtual Server is the server or server(s) behind NAT (on the LAN), for example, Web server or

The protocol used for this application.

¾

Start

&

End port number:

Enter the specific Start and End Port number you want to forward.

Step 2:

Select the Rule index for the rule as shown in Figure 4-30.

Step 3:

Select the application you want from drop-down list, then the protocol and port number

will be added to the corresponding field automatically, you only need to configure the IP

address for the virtual server; If the application list does not contain the service that you

want, please configure the Port number, IP Address and Protocol manually.

Step 4:

After that, click
