Management

19.1 Overview

This chapter explains how to configure TR-069 and remote management on the NVG2053.

19.1.1What You Can Do in this Chapter

•Use the TR-069 screen (Section 19.5 on page 204) to configure the NVG2053’s TR-069 auto-configuration settings.

•Use the WWW screen (Section 19.5 on page 204) to configure the NVG2053’s HTTP management settings.

•Use the Telnet screen (Section 19.5 on page 204) to specify which interfaces allow Telnet access and from which IP address the access can come.

•Use the ICMP screen (Section 19.6 on page 205) to specify which of the NVG2053’s interfaces will respond to Ping requests.

19.2 What You Need To Know

Firewall Rules

When you configure remote management to allow management from any network except the LAN, you still need to configure a firewall rule to allow access. See Chapter 13 on page 251 for details on configuring firewall rules.

You can also disable a service on the NVG2053 by not allowing access for the service/protocol through any of the NVG2053 interfaces.

Remote Management Sessions

You may only have one remote management session running at a time. The NVG2053 automatically disconnects a remote management session of lower priority when another remote management session of higher priority starts. The priorities for the different types of remote management sessions are as follows.

Remote Management Limitations

Remote management does not work when:

1You have not enabled that service on the interface in the corresponding remote management screen.

2You have disabled that service in one of the remote management screens.

3The IP address in the Secured Client IP Address field does not match the client IP address. If it does not match, the NVG2053 will disconnect the session immediately.

4There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time.

5There is a firewall rule that blocks it.

System Timeout

There is a default system management idle timeout of five minutes (three hundred seconds). The NVG2053 automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling. You can change the timeout period in the Maintenance > General screen.

19.3 The TR-069 Screen

TR-069 defines how Customer Premise Equipment (CPE), for example your NVG2053, can be managed over the WAN by an Auto Configuration Server (ACS). TR-069 is based on sending Remote Procedure Calls (RPCs) between an ACS and a client device. RPCs are sent in Extensible Markup Language (XML) format over HTTP or HTTPS.

An administrator can use an ACS to remotely set up the NVG2053, modify settings, perform firmware upgrades as well as monitor and diagnose the NVG2053. You have to enable the device to be managed by the ACS and specify the ACS IP address or domain name and username and password.
