NAT Traversal Settings
The
NAT Traversal
Settings
page is divided into separate pages used to configure SIP NAT parameters, RTP and STUN parameters for NAT and a
page where the NAT Exclusion table may be filled.
Use NAT Traversal for SIP
checkbox applies to all pages and is used to enable NAT traversal for the SIP traffic, hence any incoming and outgoing
SIP messages from and to the Quadro will be routed through the NAT PC.
The
SIP Parameters
page is used to configure NAT specific
settings for SIP. and offers two independent group of settings:
UDP Parameters
:
Manipulation radio buttons allow 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 to define
manually 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.
Fig. II-60: SIP Parameters page
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 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 to define manually
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 for FXS Lines
and
Mapped
RTP/RTCP Port Range for IP Lines:
•
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.
