The following table describes the labels in this screen.
15.9 TR-069
TR-069 is a standard that defines how your ZyXEL Device can be managed via a management
server such as ZyXEL’s Vantage CNM Access. TR-069 is based on sending RPCs (Remote
Procedure Call) between a management server and a client device (for example the ZyXEL
Device). RPCs are sent in XML (Extensible Markup Language) format using HTTP as a
transport protocol.
An administrator can use CNM Access to remotely set up the ZyXEL Device, modify settings,
perform firmware upgrades as well as monitor and diagnose the ZyXEL Device. All you have
to do is enable the device to be managed by CNM Access and specify the CNM Access IP
address or domain name and username and password.
Follow the procedure below to configure your ZyXEL Device to be managed by CNM Access.
See the Command Interpreter appendix for information on the command structure and how to
access the CLI (Command Line Interface) on the ZyXEL Device.

LABEL
DESCRIPTION
ICMP
Internet Control Message Protocol is a message control and error-reporting
protocol between a host server and a gateway to the Internet. ICMP uses Internet
Protocol (IP) datagrams, but the messages are processed by the TCP/IP software
and directly apparent to the application user.
Respond to Ping
on
The ZyXEL Device will not respond to any incoming Ping requests when
Disable
is
selected. Select
LAN
to reply to incoming LAN Ping requests.
Select
WAN
to reply
to incoming WAN Ping requests. Otherwise, select
LAN & WAN
to reply to both
incoming LAN and WAN Ping requests.
Do not respond to
requests for
unauthorized
services
Select this option to prevent hackers from finding the ZyXEL Device by probing for
unused ports. If you select this option, the ZyXEL Device will not respond to port
request(s) for unused ports, thus leaving the unused ports and the ZyXEL Device
unseen. By default this option is not selected and the ZyXEL Device will reply with
an ICMP Port Unreachable packet for a port probe on its unused UDP ports, and a
TCP Reset packet for a port probe on its unused TCP ports.
Note that the probing packets must first traverse the ZyXEL Device's firewall
mechanism before reaching this anti-probing mechanism. Therefore if the firewall
mechanism blocks a probing packet, the ZyXEL Device reacts based on the
firewall policy, which by default, is to send a TCP reset packet for a blocked TCP
packet. You can use the command "
sys firewall tcprst rst
[on|off]
" to change this policy. When the firewall mechanism blocks a UDP
packet, it drops the packet without sending a response packet.
