CHAPTER 14
Dynamic DNS Setup
This chapter discusses how to configure your ZyXEL Device to use Dynamic DNS.
14.1 Dynamic DNS Overview
Dynamic DNS allows you to update your current dynamic IP address with one or many
dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You
can also access your FTP server or Web site on your own computer using a domain name (for
instance myhost.dhs.org, where myhost is a name of your choice) that will never change
instead of using an IP address that changes each time you reconnect. Your friends or relatives
will always be able to call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is
for people with a dynamic IP from their ISP or DHCP server that would still like to have a
domain name. The Dynamic DNS service provider will give you a password or key.
14.1.1 DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use,
for example, www.yourhost.dyndns.org and still reach your hostname.
If you have a private WAN IP address, then you cannot use Dynamic DNS.
See Section 14.2 on page 198 for configuration instruction.
14.2 Configuring Dynamic DNS
To change your ZyXEL Device’s DDNS, click Advanced > Dynamic DNS. The screen
appears as shown.

CHAPTER 15
Remote Management
Configuration
This chapter provides information on configuring remote management.
15.1 Remote Management Overview
Remote management allows you to determine which services/protocols can access which
ZyXEL Device interface (if any) from which computers.
Note: When you configure remote management to allow management from the WAN,
you still need to configure a firewall rule to allow access.
You may manage your ZyXEL Device from a remote location via:
• Internet (WAN only)
• ALL (LAN and WAN)
• LAN only,
• Neither (Disable).
Note: When you choose WAN only or LAN & WAN, you still need to configure a
firewall rule to allow access.
To disable remote management of a service, select Disable in the corresponding Access
Status field.
You may only have one remote management session running at a time. The ZyXEL Device
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.
1Telnet
2HTTP
15.1.1 Remote Management Limitations
Remote management over LAN or WAN will not work when:
• You have disabled that service in one of the remote management screens.
P-660H/HW-D Series User’s Guide
203 Chapter 15 Remote Management Configuration
• The IP address in the Secured Client IP field does not match the client IP address. If it
does not match, the ZyXEL Device 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.
15.1.2 Remote Management and NAT
When NAT is enabled:
• Use the ZyXEL Device’s WAN IP address when configuring from the WAN.
• Use the ZyXEL Device’s LAN IP address when configuring from the LAN.
15.1.3 System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds).
The ZyXEL Device 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.

Simple Network Management Protocol (SNMP) is a protocol used for exchanging
management information between network devices. SNMP is a member of the TCP/IP
protocol suite. Your ZyXEL Device supports SNMP agent functionality, which allows a
manager station to manage and monitor the ZyXEL Device through the network. The ZyXEL
Device supports SNMP version one (SNMPv1) and version two (SNMPv2). The next figure
illustrates an SNMP management operation.
Note: SNMP is only available if TCP/IP is configured.

207 Chapter 15 Remote Management Configuration
Figure 114 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the ZyXEL
Device). An agent translates the local management information from the managed device into
a form compatible with SNMP. The manager is the console through which network
administrators perform network management functions. It executes applications that control
and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection
of managed objects. SNMP allows a manager and agents to communicate for the purpose of
accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol
operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list
within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table
from an agent, it initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
15.6.1 Supported MIBs
The ZyXEL Device supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of
the MIBs is to let administrators collect statistical data and monitor status and performance.
P-660H/HW-D Series User’s Guide

15.6.2 SNMP Traps
The ZyXEL Device will send traps to the SNMP manager when any one of the following
events occurs:

1warmStart (defined in RFC-1215)A trap is sent after booting (software reboot).
6whyReboot (defined in ZYXEL-
MIB)
A trap is sent with the reason of restart before
rebooting when the system is going to restart (warm
start).
6a For intentional reboot: A trap is sent with the message "System reboot by
user!" if reboot is done intentionally, (for example,
download new files, CI command "sys reboot", etc.).
6b For fatal error: A trap is sent with the message of the fatal code if the
system reboots because of fatal errors.

If an outside user attempts to probe an unsupported port on your ZyXEL Device, an ICMP
response packet is automatically returned. This allows the outside user to know the ZyXEL
Device exists. Your ZyXEL Device supports anti-probing, which prevents the ICMP response
packet from being sent. This keeps outsiders from discovering your ZyXEL Device when
unsupported ports are probed.

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
corresponding firewall policy to send a TCP reset packet for a blocked TCP packet
or an ICMP port-unreachable packet for a blocked UDP packets or just drop the
packets without sending a response packet.

CHAPTER 16
Universal Plug-and-Play (UPnP)
This chapter introduces the UPnP feature in the web configurator.
16.1 Introducing Universal Plug and Play
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP
for simple peer-to-peer network connectivity between devices. A UPnP device can
dynamically join a network, obtain an IP address, convey its capabilities and learn about other
devices on the network. In turn, a device can leave a network smoothly and automatically
when it is no longer in use.
See Section 16.2.1 on page 215 for configuration instructions.
16.1.1 How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP).
Each UPnP compatible device installed on your network will appear as a separate icon.
Selecting the icon of a UPnP device will allow you to access the information and properties of
that device.
16.1.2 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through
NAT. UPnP network devices can automatically configure network addressing, announce their
presence in the network to other UPnP devices and enable exchange of simple product and
service descriptions. NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
P-660H/HW-D Series User’s Guide
215 Chapter 16 Universal Plug-and-Play (UPnP)
16.1.3 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and
opening firewall ports may present network security issues. Network information and
configuration may also be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the ZyXEL Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
16.2 UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device
(IGD) 1.0.
See the following sections for examples of installing and using UPnP.

Server
Select this radio button to have the ZyXEL Device get the time and date from the
time server you specified below.
Time Protocol Select the time service protocol that your time server uses. Not all time servers
support all protocols, so you may have to check with your ISP/network
administrator or use trial and error to find a protocol that works.
The main difference between them is the format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC 868) format displays a 4-byte integer giving the total number of
seconds since 1970/1/1 at 0:0:0.
The default, NTP (RFC 1305), is similar to Time (RFC 868).
Time Server
Address
Enter the IP address or URL (up to 20 extended ASCII characters in length) of
your time server. Check with your ISP/network administrator if you are unsure of
this information.

your time zone and Greenwich Mean Time (GMT).
Enable Daylight
Savings
Daylight saving is a period from late spring to early fall when many countries set
their clocks ahead of normal local time by one hour to give more daytime light in
the evening.
Select this option if you use Daylight Saving Time.

Start Date Configure the day and time when Daylight Saving Time starts if you selected
Enable Daylight Saving. The o'clock field uses the 24 hour format. Here are a
couple of examples:
Daylight Saving Time starts in most parts of the United States on the first Sunday
of April. Each time zone in the United States starts using Daylight Saving Time at
2 A.M. local time. So in the United States you would select First, Sunday, April
and type 2 in the o'clock field.
Daylight Saving Time starts in the European Union on the last Sunday of March.
All of the time zones in the European Union start using Daylight Saving Time at
the same moment (1 A.M. GMT or UTC). So in the European Union you would
select Last, Sunday, March. The time you type in the o'clock field depends on
your time zone. In Germany for instance, you would type 2 because Germany's
time zone is one hour ahead of GMT or UTC (GMT+1).
End Date Configure the day and time when Daylight Saving Time ends if you selected
Enable Daylight Saving. The o'clock field uses the 24 hour format. Here are a
couple of examples:
Daylight Saving Time ends in the United States on the last Sunday of October.
Each time zone in the United States stops using Daylight Saving Time at 2 A.M.
local time. So in the United States you would select Last, Sunday, October and
type 2 in the o'clock field.
Daylight Saving Time ends in the European Union on the last Sunday of October.
All of the time zones in the European Union stop using Daylight Saving Time at the

CHAPTER 18
Logs
This chapter contains information about configuring general log settings and viewing the
ZyXEL Device’s logs. Refer to the appendix for example log message explanations.
18.1 Logs Overview
The web configurator allows you to choose which categories of events and/or alerts to have
the ZyXEL Device log and then display the logs or have the ZyXEL Device send them to an
administrator (as e-mail) or to a syslog server.
18.1.1 Alerts and Logs
An alert is a type of log that warrants more serious attention. They include system errors,
attacks (access control) and attempted access to blocked web sites. Some categories such as
System Errors consist of both logs and alerts. You may differentiate them by their color in the
View Log screen. Alerts display in red and logs display in black.
18.2 Viewing the Logs
Click Maintenance > Logs to open the View Log screen. Use the View Log screen to see the
logs for the categories that you selected in the Log Settings screen (see Section 18.3 on page
233).
Log entries in red indicate alerts. The log wraps around and deletes the old entries after it fills.
Click a column heading to sort the entries. A triangle indicates ascending or descending sort
order.
