Nat - Encore ENDSL-A2+R2 User Manual

4.4.3 NAT

Network Address Translation (NAT) is a method for disguising the private IP addresses you
use on your LAN as the public IP address you use on the Internet. You define NAT rules that
specify exactly how and when to translate between public and private IP addresses. Simply
select this option to setup the NAT function for your ADSL router.
Virtual Circuit (VC): The Virtual Circuit (VC) properties of the ATM VC interface identify a
unique path that your ADSL/Ethernet router uses to communicate via the ATM-based network
with the telephone company central office equipment.
NAT Status: This filed shows the current status of the NAT function for the current VC.
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.
Note: For VCs with single IP, they share the same DMZ & Virtual servers; for VCs with multiple
IPs, each VC cab 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.
