User's Manual 426 Document #: LTRT-65422
MP-11x & MP-124
Parameter Description
Web: STUN Server Primary IP
EMS: Primary Server IP
[STUNServerPrimaryIP]
Defines the IP address of the primary STUN server.
The valid range is the legal IP addresses. The default is 0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
Web: STUN Server Secondary
IP
EMS: Secondary Server IP
[STUNServerSecondaryIP]
Defines the IP address of the secondary STUN server.
The valid range is the legal IP addresses. The default is 0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
[STUNServerDomainName] Defines the domain name for the Simple Traversal of User
Datagram Protocol (STUN) server's address (used for retrieving all
STUN servers with an SRV query). The STUN client can perform the
required SRV query to resolve this domain name to an IP address
and port, sort the server list, and use the servers according to the
sorted list.
Notes:

For this parameter to take effect, a device reset is required.

Use either the STUNServerPrimaryIP or the
STUNServerDomainName parameter, with priority to the first
one.
NAT Parameters
Web/EMS: NAT Traversal
[DisableNAT]
Enables the NAT mechanism. For more information, see 'First
Incoming Packet Mechanism' on page
127 .

[0] Enable

[1] Disable (default)
Web: NAT IP Address
EMS: Static NAT IP Address
[StaticNatIP]
Defines the global (public) IP address of the device to enable static
NAT between the device and the Internet.
Note: For this parameter to take effect, a device reset is required.
EMS: Binding Life Time
[NATBindingDefaultTimeout]
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.
[EnableIPAddrTranslation] Enables IP address translation for RTP, RTCP, and T.38 packets.

[0] = Disable IP address translation.

[1] = (Default) Enable IP address translation.

[2] = Enable IP address translation for RTP Multiplexing
(ThroughPacket™).

[3] = Enable IP address translation for all protocols (RTP, RTCP,
T.38 and RTP Multiplexing).
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).
