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 RTP Settings page.

The STUN Parameters page enables auto
matic NAT
configuration through the STUN server and is used to configure
the STUN (Simple Traversal of UDP over NAT) client on the
Quadro. This page requires the following data to be inserted:
The STUN Server text field requires the STUN server’s
hostname or IP address. The STUN Port text field requires the
STUN server port number.
The Secondary STUN Server and Secondary STUN Port text
fields respectively require the parameters of the secondary
STUN server.
The Polling Interval drop down list contains the possible time
intervals between referrals to the STUN server.

The Keep-alive interval text field provides the options to select the time interval (in seconds) for keeping NAT mapping alive. The value should be in
the range of 10 to 300 seconds.
The NAT IP checking interval text field indicates the interval (in seconds) between the NAT IP checking attempts (used to distinguish the possible
NAT IP address changes and to perform registration on the new host). The value should be in the range of 10 to 3600.
The NAT Exclusion Table lists all possible IP ranges that are not included in the NAT process, but may be accessed directly. IP addresses that are
not listed in the NAT Exclusion Table are accessed over NAT. For example, if a Quadro user needs to make SIP calls within the local network as
well as outside of that network, all local IP addresses are required to be excluded from NAT traversal settings by being listed in this table. Otherwise,
a malfunction may occur in SIP operations.
The NAT Exclusion Table page
offers the following input
options:
Each record in the table has a corresponding checkbox
assigned to its row. The checkbox is used to delete or to edit
the corresponding record. Only one record may be edited at a
time. An error message will appear if no selection is made or
more than one is selected.
Each column heading in the table is a link. By clicking on the
column heading, the table will be sorted by the selected column.
When sorting (ascending or descending), arrows will be
displayed next to the column heading.
Add opens the Add Entry page where a new IP range can be
added.

The Add Entry page includes the following text fields:
IP address requires the IP address that is placed behind NAT
within the local network.
Subnet Mask requires the subnet mask corresponding to the
specified IP address.

To Configure the NAT Exclusion Table
1. Press the Add button on the NAT Exclusion Table page. The Add Entry page will appear in the browser window.
2. Specify an IP Address and its Subnet Mask in the corresponding text fields.
