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 SIP traffic will be routed

through NAT server.

• Disable – with this selection, no SIP traffic will be routed

through 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.

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 for FXS 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

RTP Settings page.
