STUN Parameters
The
STUN Parameters
page enables automatic NAT configuration
through the STUN server and is used to configure the STUN
(Simple Traversal of UDP over NAT) client on the QX. 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.
NAT Exclusion
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 QX 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.
