SIP User's Manual 6. Configuration Parameters Reference
6.1.5 NAT Parameters
The Network Address Translation (NAT) parameters are described in the table below.
Table 6-5: NAT Parameters
Parameter Description
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 value is 30.
Note: For this parameter to take effect, a device reset is required.
Web: NAT IP Address
EMS: Static NAT IP Address
[StaticNatIP]
Global (public) IP address of the device to enable static Network
Address Translation (NAT) between the device and the Internet.
Note: For this parameter to take effect, a device reset is required.
EMS: Disable NAT
[DisableNAT]
Enables / disables the Network Address Translation (NAT)
mechanism.
 [0] = Enabled.
 [1] = Disabled (default).
Note: The compare operation that is performed on the IP address is
enabled by default and is controlled by the parameter
EnableIPAddrTranslation. The compare operation that is performed
on the UDP port is disabled by default and is controlled by the
parameter EnableUDPPortTranslation.
[EnableIPAddrTranslation]
Enables IP address translation for RTP, RTCP, and T.38 packets.
 [0] = Disable IP address translation.
 [1] = Enable IP address translation (default).
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.
Note: The NAT mechanism must be enabled for this parameter to
take effect (i.e., the parameter DisableNAT is set to 0).
[EnableUDPPortTranslation]
 [0] = Disable UDP port translation (default).
 [1] = Enable UDP port translation.
When enabled, 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., DisableNAT = 0,
EnableIpAddrTranslation = 1).
