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.

Chapter 19 Management
Telnet
HTTP
Remote Management Limitations
Remote management does not work when:
You have not enabled that service on the interface in the corresponding remote
management screen.
You have disabled that service in one of the remote management screens.
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.
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.
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.

features on the NVG2053.
Wireless Functionality
Allows IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n
wireless clients to connect to the NVG2053 wirelessly. Enable
wireless security ( WPA(2)-PSK) and/or MAC filtering to protect
your wireless network.
Note: The NVG2053 may be prone to RF (Radio
Frequency) interference from other 2.4 GHz devices
such as microwave ovens, wireless phones,
Bluetooth enabled devices, and other wireless LANs.
Firmware Upgrade
Download new firmware (when available) from the ZyXEL web
site and use the Web Configurator to put it on the NVG2053.
Note: Only upload firmware for your specific model!

Configuration Backup &
Restoration
Make a copy of the NVG2053’s configuration and put it back on
the NVG2053 later if you decide you want to revert back to an
earlier configuration.
Network Address
Translation (NAT)
Each computer on your network must have its own unique IP
address. Use NAT to convert a single public IP address to
multiple private IP addresses for the computers on your
network.
Firewall
You can configure firewall on the NVG2053 for secure Internet
access. When the firewall is on, by default, all incoming traffic
from the Internet to your network is blocked unless it is
initiated from your network. This means that probes from the
outside to your network are not allowed, but you can safely
browse the Internet and download files for example.
Remote Management
This allows you to decide whether a service (HTTP or Telnet
traffic for example) from a computer on a network (LAN or
WAN for example) can access the NVG2053.
Wireless LAN Scheduler
You can schedule the times the Wireless LAN is enabled/
disabled.
Time and Date
Get the current time and date from an external server when
you turn on your NVG2053. You can also set the time manually.
These dates and times are then used in logs.
