NAT Traversal Settings

The NAT Traversal Settings page is divided into separate pages used to configure General NAT settings, SIP NAT parameters, RTP and STUN
parameters for NAT and a page where the NAT Exclusion table may be filled.
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 Host 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 Host 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.
