NAT Status: This field shows the current status of the NAT function for the current VC. You
can go to the previous screen (shown in Figure 4-4) to activate the function.
Number of IPs; This field is to specify how many IPs are provided by your ISP for current VC.
It can be single IP or multiple IPs. We select Multiple to explain.
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.

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