CHAPTER 19
Management
19.1 Overview
This chapter explains how to configure TR-069 and remote management on the
NVG2053.
19.1.1 What 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.

2 HTTP
Remote Management Limitations
Remote management does not work when:
1 You have not enabled that service on the interface in the corresponding remote
management screen.
2 You have disabled that service in one of the remote management screens.
3 The 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.
4 There 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.
5 There 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.
