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>)#

source-ip-address

Defines the source IP address (IPv4 or IPv6). Outgoing packets sent from this IP address are NAT'ed.

Note: The parameter is applicable only to Mediant VE in HA mode that is deployed on the Azure cloud platform.

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.

src-start-port

Defines the optional starting port range (0-65535) of the IP interface, used as matching criteria for the NAT rule.

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
