The
General Settings
page consists of a manipulation radio buttons
group to select the mode of the NAT Traversal usage for the SIP traffic
(any incoming and outgoing SIP messages from and to the Quadro will
be routed through the NAT PC).
•
Automatic
– with this selection, system will analyze the Quadro’s
WAN IP address and if it is in the IP range specified for local
networks (according to RFC), the SIP traffic will be routed through
NAT. Otherwise, if Quadro’s WAN IP address is outside the
specified IP range, no SIP traffic will be routed through NAT server.
•
Force
– with this selection, all the SIP traffic will be routed through
the NAT server.
•
Disable
– with this selection, no SIP traffic will be routed through the
NAT server.

The
SIP Parameters
page is used to configure NAT specific settings for SIP and offers two independent groups of settings:
UDP Parameters
:
Manipulation radio buttons allow you to select the type of connection over
NAT:
Selecting
Use STUN
will switch to automatic discovery of Mapped
settings for the SIP UDP traffic over NAT. STUN settings are
configured on the STUN parameters page (see below).
Selecting
Use Manual NAT Traversal
allows you to manually define
the mapped settings for the SIP UDP traffic over NAT:
Mapped Hos
t requires the IP address of the mapped host for SIP UDP
traffic over NAT.
Mapped Port
requires the port number on the mapped host for the SIP
UDP traffic over NAT.
TCP Parameters:
Mapped Hos
t requires the IP address of the mapped host for SIP TCP
traffic over NAT.
Mapped Port
requires the port number on the mapped host for the SIP
TCP traffic over NAT.

The
RTP Parameters
page is used to choose between the STUN and
Manual NAT traversal connection for the RTP traffic and to define the
RTP/RTCP ports for the connection over NAT.
Manipulation radio buttons allow you to select the type of connection over
NAT:
Selecting
Use STUN
will switch to automatic discovery of Mapped
settings for the RTP UDP traffic over NAT. STUN settings are configured
on the STUN Parameters page (see below).
Selecting
Use Manual NAT Traversal
allows you to manually define the
RTP/RTCP port ranges for the RTP traffic over NAT:
•
The
Mapped Host
text fields require the Mapped Host for RTP
traffic over NAT.
•
Mapped RTP/RTCP Port Range:
Min
- minimal port has to be higher than 1024 and lower than the
maximal port range. Only even numbers are allowed.
Max
- maximal port has to be lower than 65536 and higher than the
minimal port range. Only odd numbers are allowed.
Please Note:
RTP/RTCP Mapped Port ranges should be greater than or
equal to the RTP/RTCP port ranges defined on the
page.
