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 analize 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 parsed over 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 SIP traffic will be routed
through NAT server.
• Disable – with this selection, no SIP traffic will be routed
through NAT server.

settings for SIP. and offers two independent group of settings:

Selecting Use Manual NAT Traversal allows to define
manually 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.
