– 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 realized 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 – identifies the method that will be used by client for obtaining its public address
information. The following modes are possible:
STUN – use STUN protocol for public address determination;
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 mode, you should define the following settings:
– STUN server address – STUN server IP address or domain name;
– STUN server port – STUN server UDP port (default value is 3478);
– 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.
When Manual mode is selected, client public address should be entered with NAT address setting (in IPv4
format).
