nat-translation

This command configures the NAT Translation table, which lets you define network address translation (NAT) rules for translating source IP addresses per VoIP interface (SIP control and RTP media traffic) into NAT IP addresses (global - public) when the device is located behind NAT.

Syntax

(config-network)# nat-translation <Index>
(nat-translation-<Index>)# 

Command	Description
Index	Defines the table row index.
src-end-port	Defines the optional ending port range (0-65535) of the IP interface, used as matching criteria for the NAT rule.
src-interface-name	Assigns an IP network interface (configured in the IP Interfaces table) to the rule. Outgoing packets sent from the specified network interface are NAT'ed.
network-source	Defines the alias name representing a VRF or an IP address of the source network interface that is used to bind to the SIP application.
src-start-port	Defines the optional starting port range (0-65535) of the IP interface, used as matching criteria for the NAT rule.
target-end-port	Defines the optional ending port range (0-65535) of the global address.
target-ip-address	Defines the global (public) IP address.
target-start-port	Defines the optional starting port range (0-65535) of the global address.

Example

This example configures a NATed IP address (202.1.1.1) for all traffic sent from IP network interface "voice":

# configure network
(config-network)# nat-translation 0
(nat-translation-0)# src-interface-name voice
(nat-translation-0)# target-ip-address 202.1.1.1
