Network Address Translation (NAT)
NAT is a mechanism that allows IP addressing scheme to be hidden from any TCP/IP network to which TCP/IP traffic is routed. For example, an established network may be using a numbering scheme that is not consistent
The IPNC Network Address Translation (NAT) functionality allows an IP address or network (Internal) to be translated to single globally unique IP address (external). In this way
–Single IP Address Internet connectivity.
–Network address translation (NAT) allows an existing TCP/IP network- addressing scheme to be used for connection to the Internet.
NAT is automatically enabled on the IPNC under the following connection scenarios:
Condition | NAT status |
Service / Advanced IP Mask = 255.255.255.255 | On |
|
|
The IPNC is offered and accepts an IP address during the | On |

|
Service / Advanced IP Address = Blank |
|
A mask other than | Disabled. |
