Version 6.6 649 Mediant 3000
User's Manual 53. Configuration Parameters Reference
Parameter Description
Address
[StaticNatIP]
Note: For this parameter to take effect, a device reset is required.
EMS: Binding Life Time
[NATBindingDefaultTim
eout]
Defines the default NAT binding lifetime in seconds. STUN refreshes
the binding information after this time expires.
The valid range is 0 to 2,592,000. The default is 30.
Note: For this parameter to take effect, a device reset is required.
[EnableIPAddrTranslatio
n] Enables IP address translation for RTP, RTCP, and T.38 packets.

[0] = Disable IP address translation.

[1] = (Default) Enable IP address translation.
When enabled, the device compares the source IP address of the first
incoming packet to the remote IP address stated in the opening of the
channel. If the two IP addresses don't match, the NAT mechanism is
activated. Consequently, the remote IP address of the outgoing stream
is replaced by the source IP address of the first incoming packet.
Notes:

The NAT mechanism must be enabled for this parameter to take
effect (i.e., the parameter DisableNAT is set to 0).

For information on RTP Multiplexing, see RTP Multiplexing
(ThroughPacket).
[EnableUDPPortTranslat
ion] Enables UDP port translation.

[0] = (Default) Disables UDP port translation.

[1] = Enables UDP port translation. The device compares the source
UDP port of the first incoming packet to the remote UDP port stated
in the opening of the channel. If the two UDP ports don't match, the
NAT mechanism is activated. Consequently, the remote UDP port of
the outgoing stream is replaced by the source UDP port of the first
incoming packet.
Notes:

For this parameter to take effect, a device reset is required.

The NAT mechanism and the IP address translation must be
enabled for this parameter to take effect (i.e., set the parameter
DisableNAT to 0 and the parameter EnableIpAddrTranslation to 1).
53.1.6 NFS Parameters
The Network File Systems (NFS) configuration parameters are described in the table
below.
NFS Parameters
Parameter Description
[NFSBasePort]
Defines the start of the range of numbers used for local UDP ports used
by the NFS client. The maximum number of local ports is maximum
channels plus maximum NFS servers.
The valid range is 0 to 65535. The default is 47000.
