Static NAT Mapping

The Static NAT Mapping object is a child of the Static NAT Mappings object. It allows you to configure the Network Address Translation (NAT) mapping between IP addresses on an internal network (containing the NE) and those on an external network (containing Subscriber Gateways, Trunk / Access Gateways and SIP subscribers). You need to configure a Static NAT Mapping object for each range of IP addresses that needs to be mapped.


Parameter

Access

Description
Static NAT - first internal IP address Change The first address in the IP address range used in the internal network (the same network as the NE). This is a standard dotted-decimal IPv4 address.
Static NAT - last internal IP address Change The last address in the IP address range used in the internal network. This is a standard dotted-decimal IPv4 address, which must have a higher numeric value than Static NAT - first internal IP address. Alternatively, if you need to map a single address rather than a range, leave this field blank; the EMS will set it to be the same as the first internal IP address (that is, the range contains only one address).
Static NAT - first external IP address Change The first address in the IP address range used in the external network. This is a standard dotted-decimal IPv4 address.
Static NAT - last external IP address Read only The last address in the IP address range used in the external network (determined from the first external IP address and the size of the internal address range). This is a standard dotted-decimal IPv4 address.
