Virtual Circuit: Enter Virtual Circuit Index that you plan to setup for the NAT function.
NAT Status: This field shows the current status of the NAT function for the current VC.

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.

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

following screen.

whole inside network appear as a single machine to the outside world.
