Parameter Description
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 (parameter NATMode).

For information on RTP Multiplexing, see RTP Multiplexing
(ThroughPacket).
[EnableUDPPortTranslation] 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., parameter
NATMode and the parameter EnableIpAddrTranslation to 1).
