Valid Range and Description
NATBindingDefaultTimeo
ut
Defines the default NAT binding lifetime in seconds. STUN is used to
refresh the binding information after this time expires.
The valid range is 0 to 2,592,000. The default value is 30.
DisableNAT
Enables / disables the Network Address Translation (NAT) mechanism.
ƒ
[0]
= Enabled.
ƒ
[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
ƒ
[0]
= Disable IP address translation.
ƒ
[1]
= Enable IP address translation for RTP, RTCP and T.38 packets
(default).
ƒ
[2]
= Enable IP address translation for ThroughPacket™.
ƒ
[3]
= Enable IP address translation for all protocols (RTP, RTCP, T38
and ThroughPacket™).
When enabled, the gateway 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 (DisableNAT = 0).
EnableUDPPortTranslatio
n
ƒ
[0]
= Disable UDP port translation (default).
ƒ
[1]
= Enable UDP port translation.
When enabled, the gateway 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.
Note:
The NAT mechanism and the IP address translation must be
enabled for this parameter to take effect (DisableNAT = 0,
EnableIpAddrTranslation = 1).
NoOpEnable
Enables or disables the transmission of RTP or T.38 No-Op packets.
ƒ
[0]
= Disable (default)
ƒ
[1]
= Enable
This mechanism ensures that the NAT binding remains open during RTP
or T.38 silence periods.
