[NATBindingDefaultTimeout]
[EnableIPAddrTranslation]
Version 6.4
0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
Defines the IP address of the secondary STUN server.
The valid range is the legal IP addresses. The default value is
0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
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.
Enables the NAT mechanism.

[0] Enable

[1] Disable (default)
Note: The compare operation that is performed on the IP address is
enabled by default and is configured by the parameter
EnableIPAddrTranslation. The compare operation that is performed
on the UDP port is disabled by default and is configured by the
parameter EnableUDPPortTranslation.
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.
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 value is 30.
Note: For this parameter to take effect, a device reset is required.
Enables IP address translation for RTP, RTCP, and T.38 packets.

[0] = Disable IP address translation.

[1] = Enable IP address translation (default).

[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
