Configuring A Static Nat Ip Address For All Interfaces - AudioCodes Mediant 800B User Manual

User's Manual
a. If configured, uses the single Static NAT IP address for all interfaces - see
''Configuring a Static NAT IP Address for All Interfaces'' on page 135.
b. If configured, uses the NAT Translation table which configures NAT per interface - see
Configuring NAT Translation per IP Interface on page 136.
If NAT is not configured by any of the above-mentioned methods, the device sends the
packet according to its IP address configured in the Interface table.
Note:
The figure below illustrates the NAT problem faced by the SIP networks where the device
is located behind a NAT:

Configuring a Static NAT IP Address for All Interfaces

You can configure a global (public) IP address of the router to enable static NAT between
the device and the Internet for all network interfaces. Thus, the device replaces the source
IP address for media of all outgoing SIP messages sent on any of its network interfaces to
this public IP address.
The following procedure describes how to configure a static NAT address in the Web
interface. You can also configure this using the ini file parameter, StaticNATIP or CLI
command, configure voip > sip-definition general-settings > nat-ip-addr.

To configure a single static NAT IP address:
1. Open the SIP General Parameters page (Configuration tab > VoIP menu > SIP
Definitions > General Parameters).
