27 VoIP Subscriber Gateways
- Periodic inform enable – when checked, integrated TR-069 client performs periodic ACS
server polling at intervals equal to 'Periodic inform interval' value, in seconds. Goal of
the polling is to identify possible changes in the device configuration.
ACS connection request:
- Username, Password – username and password used by client to access ACS server.
Client connection request:
- Username, Password – username and password used by ACS server to access TR-069
client.
Software updating, changing and reading a current configuration, rebooting and resetting to the
default settings can be implemented via TR-069 protocol.
NAT settings:
If there is a NAT (network address translation) between the client and ACS server, ACS server
may not be able to establish the connection to client without specific technologies intended to prevent
such situations. These technologies allow the client to identify its so-called public address (NAT
address or in other words external address of a gateway that covers the client.) When public address is
identified, the client reports it to the server that uses this public address for establishing connection to
the client in the future.
- NAT Mode - determines how the client should receive information about their public
address. Available modes:
STUN – use STUN protocol for public address identification;
Manual – manual mode, when public address is explicit in configuration; in this
mode, you should add a forwarding rule on a device that acts as a NAT for TCP port
used by TR-069 client;
Off–NAT will not be used – this mode is recommended only when the device is
directly connected to ACS server without network address translation. In this case,
public address will match local client address.
When choosing STUN client operation mode, you should define the following settings:
- STUN server address – STUN server IP address or domain name;
- STUN server port – STUN server UDP port (3478 by default);
- Minimum keep alive period, seconds and Maximum keep alive period, seconds – define
the time interval in seconds for periodic transmission of messages to STUN server in
order to identify public address modification.
