Static Route
16.1 Overview
The ZyXEL Device usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the ZyXEL Device send data to
devices not reachable through the default gateway, use static routes.
For example, the next figure shows a computer (A) connected to the ZyXEL
Device’s LAN interface. The ZyXEL Device routes most traffic from A to the
Internet through the ZyXEL Device’s default gateway (R1). You create one static
route to connect to services offered by your ISP behind router R2. You create
another static route to communicate with a separate network behind a router R3
connected to the LAN.

802.1Q/1P
17.1 Overview
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned
into multiple logical networks. A VLAN group can be treated as an individual
device. Each group can have its own rules about where and how to forward traffic.
You can assign any ports on the ZyXEL Device to a VLAN group and configure the
settings for the group. You may also set the priority level for traffic transmitted
through the ports.

Ports
VLAN Groups
802.1P
Priority Levels
17.1.1 What You Can Do in the 802.1Q/1P Screens
• Use the Group Setting screen (Section 17.2 on page 324) to activate 802.1Q/
1P, specify the management VLAN group, display the VLAN groups and
configure the settings for each VLAN group.
• Use the Port Setting screen (Section 17.3 on page 327) to configure the PVID
and assign traffic priority for each port.
17.1.2 What You Need to Know About 802.1Q/1P
IEEE 802.1P Priority
IEEE 802.1P specifies the user priority field and defines up to eight separate traffic
types by inserting a tag into a MAC-layer frame that contains bits to define class of
service.
P-2612HWU-F1 User’s Guide
317
Chapter 17 802.1Q/1P
IEEE 802.1Q Tagged VLAN
Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the
VLAN membership of a frame across bridges - they are not confined to the device
on which they were created. The VLAN ID associates a frame with a specific VLAN
and provides the information that devices need to process the frame across the
network.
PVC
A virtual circuit is a logical point-to-point circuit between customer sites.
Permanent means that the circuit is preprogrammed by the carrier as a path
through the network. It does not need to be set up or torn down for each session.
Forwarding Tagged and Untagged Frames
Each port on the device is capable of passing tagged or untagged frames. To
forward a frame from an 802.1Q VLAN-aware device to an 802.1Q VLAN-unaware
device, the ZyXEL Device first decides where to forward the frame and then strips
off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware device to an
802.1Q VLAN-aware switch, the ZyXEL Device first decides where to forward the
frame, and then inserts a VLAN tag reflecting the ingress port's default VID. The
default PVID is VLAN 1 for all ports, but this can be changed.
Whether to tag an outgoing frame depends on the setting of the egress port on a
per-VLAN, per-port basis (recall that a port can belong to multiple VLANs). If the
tagging on the egress port is enabled for the VID of a frame, then the frame is
transmitted as a tagged frame; otherwise, it is transmitted as an untagged frame.

traffic. You want to set a lower priority for this type of traffic, so you want to group
these ports and PVC2 into one VLAN (VLAN3). PVC2 priority is set to low level of
service.
SSID1 and SSID2 are two wireless networks. You want to create medium priority
for this type of traffic, so you want to group these ports and PVC3 into one VLAN
(VLAN4). PVC3 priority is set to medium level of service.

Quality of Service (QoS)
This chapter contains information about configuring QoS, editing classifiers and
viewing the ZyXEL Device’s QoS packet statistics.
18.1 Overview
This chapter discusses the ZyXEL Device’s QoS screens. Use these screens to set
up your ZyXEL Device to use QoS for traffic management.
Quality of Service (QoS) refers to both a network’s ability to deliver data with
minimum delay, and the networking methods used to control the use of
bandwidth. QoS allows the ZyXEL Device to group and prioritize application traffic
and fine-tune network performance.
Without QoS, all traffic data is equally likely to be dropped when the network is
congested. This can cause a reduction in network performance and make the
network inadequate for time-critical application such as video-on-demand.
The ZyXEL Device assigns each packet a priority and then queues the packet
accordingly. Packets assigned a high priority are processed more quickly than
those with low priority if there is congestion, allowing time-sensitive applications
to flow more smoothly. Time-sensitive applications include both those that require
a low level of latency (delay) and a low level of jitter (variations in delay) such as
Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a
problem such as Internet radio or streaming video.
• See Section 18.5 on page 341 for advanced technical information on SIP.
18.1.1 What You Can Do in the QoS Screens
• Use the General screen (Section 18.2 on page 333) to enable QoS on the
ZyXEL Device, decide allowable bandwidth using QoS and configure priority
mapping settings for traffic that does not match a custom class.
• Use the Class Setup screen (Section 18.3 on page 335) to set up classifiers to
sort traffic into different flows and assign priority and define actions to be
performed for a classified traffic flow.
P-2612HWU-F1 User’s Guide
329
Chapter 18 Quality of Service (QoS)
• Use the Monitor screen (Section 18.4 on page 341) to view the ZyXEL Device’s
QoS-related packet statistics.
18.1.2 What You Need to Know About QoS
QoS versus Cos
QoS is used to prioritize source-to-destination traffic flows. All packets in the same
flow are given the same priority. CoS (class of service) is a way of managing traffic
in a network by grouping similar types of traffic together and treating each type as
a class. You can use CoS to give different priorities to different packet types.
CoS technologies include IEEE 802.1p layer 2 tagging and DiffServ (Differentiated
Services or DS). IEEE 802.1p tagging makes use of three bits in the packet
header, while DiffServ is a new protocol and defines a new DS field, which replaces
the eight-bit ToS (Type of Service) field in the IP header.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DSCP (DiffServ
Code Point) value, IEEE 802.1p priority level and VLAN ID number in a matched
packet. When the packet passes through a compatible network, the networking
device, such as a backbone switch, can provide specific treatment or service
based on the tag or marker.
18.1.3 QoS Class Setup Example
In the following figure, your Internet connection has an upstream transmission
speed of 50 Mbps. You configure a classifier to assign the highest priority queue
(6) to VoIP traffic from the LAN interface, so that voice traffic would not get
delayed when there is network congestion. Traffic from the boss’s IP address
(192.168.1.23 for example) is mapped to queue 5. Traffic that does not match

LABEL
DESCRIPTION
Active QoS
Select the check box to turn on QoS to improve your network performance.
You can give priority to traffic that the ZyXEL Device forwards out through
the WAN interface. Give high priority to voice and video to make them run
more smoothly. Similarly, give low priority to many large file downloads so
that they do not reduce the quality of other applications.
WAN
Managed
Bandwidth
Enter the amount of bandwidth for the WAN interface that you want to
allocate using QoS.
The recommendation is to set this speed to match the interface’s actual
transmission speed. For example, set the WAN interface speed to 100000
kbps if your Internet connection has an upstream transmission speed of 100
Mbps.
Setting this number higher than the interface’s actual transmission speed
will stop lower priority traffic from being sent if higher priority traffic uses all
of the actual bandwidth.
If you set this number lower than the interface’s actual transmission speed,
the ZyXEL Device will not use some of the interface’s available bandwidth.

These fields are ignored if traffic matches a class you configured in the
Class Setup screen.
If you select ON and traffic does not match a class configured in the Class
Setup screen, the ZyXEL Device assigns priority to unmatched traffic based
on the IEEE 802.1p priority level, IP precedence and/or packet length. See
Section 18.5.4 on page 343 for more information.
If you select OFF, traffic which does not match a class is mapped to queue
two.

P-2612HWU-F1 User’s Guide
341
Chapter 18 Quality of Service (QoS)
18.5.1 IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to
identify the VLAN membership of a frame across bridges. A VLAN tag includes the
12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a
specific VLAN and provides the information that devices need to process the frame
across the network.
IEEE 802.1p specifies the user priority field and defines up to eight separate traffic
types. The following table describes the traffic types defined in the IEEE 802.1d
standard (which incorporates the 802.1p).
Table 111 IEEE 802.1p Priority Level and Traffic Type
PRIORITY
LEVEL
TRAFFIC TYPE
Level 7
Typically used for network control traffic such as router configuration
messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is the
variations in delay).
Level 5
Typically used for video that consumes high bandwidth and is sensitive to
jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA
(Systems Network Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would
include important business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk
transfers that are allowed but that should not affect other applications and
users.
Level 0
Typically used for best-effort traffic.
18.5.2 IP Precedence
Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to
prioritize packets in a layer-3 network. IP precedence uses three bits of the eightbit ToS (Type of Service) field in the IP header. There are eight classes of services
(ranging from zero to seven) in IP precedence. Zero is the lowest priority level and
seven is the highest.
18.5.3 DiffServ
QoS is used to prioritize source-to-destination traffic flows. All packets in the flow
are given the same priority. You can use CoS (class of service) to give different
priorities to different packet types.
342
P-2612HWU-F1 User’s Guide
Chapter 18 Quality of Service (QoS)
DiffServ (Differentiated Services) is a class of service (CoS) model that marks
packets so that they receive specific per-hop treatment at DiffServ-compliant
network devices along the route based on the application types and traffic flow.
Packets are marked with DiffServ Code Points (DSCPs) indicating the level of
service desired. This allows the intermediary DiffServ-compliant network devices
to handle the packets differently depending on the code points without the need to
negotiate paths or remember state information for every flow. In addition,
applications do not have to request a particular service or give advanced notice of
where the traffic is going.
DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of
Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and
a 6-bit DSCP field which can define up to 64 service levels. The following figure
illustrates the DS field.
DSCP is backward compatible with the three precedence bits in the ToS octet so
that non-DiffServ compliant, ToS-enabled network device will not conflict with the
DSCP mapping.
DSCP (6 bits)
Unused (2 bits)
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior),
that each packet gets across the DiffServ network. Based on the marking rule,
different kinds of traffic can be marked for different kinds of forwarding. Resources
can then be allocated according to the DSCP values and the configured policies.
18.5.4 Automatic Priority Queue Assignment
If you enable QoS on the ZyXEL Device, the ZyXEL Device can automatically base
on the IEEE 802.1p priority level, IP precedence and/or packet length to assign
priority to traffic which does not match a class.
The following table shows you the internal layer-2 and layer-3 QoS mapping on
the ZyXEL Device. On the ZyXEL Device, traffic assigned to higher priority queues

Dynamic DNS Setup
This chapter discusses how to configure your ZyXEL Device to use Dynamic DNS.
19.1 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 applications such
as NetMeeting and CU-SeeMe). 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.
19.1.1 What You Can Do in the DDNS Screen
Use the Dynamic DNS screen (Section 19.2 on page 346) to enable DDNS and
configure the DDNS settings on the ZyXEL Device.
19.1.2 What You Need To Know About DDNS
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.

Remote Management
Configuration
20.1 Overview
Remote management allows you to determine which services/protocols can access
which ZyXEL Device interface (if any) from which computers.The following figure
shows remote management of the ZyXEL Device coming in from the WAN.
Figure 206 Remote Management From the WAN
LAN
WAN
HTTP
Internet
Telnet
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.

Chapter 20 Remote Management Configuration
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.
Telnet
HTTP
20.1.1 What You Can Do in the Remote Management Screens
• Use the WWW screen (Section 20.2 on page 351) to configure through which
interface(s) and from which IP address(es) users can use HTTP to manage the
ZyXEL Device.
• Use the Telnet screen (Section 20.3 on page 352) to configure through which
interface(s) and from which IP address(es) users can use Telnet to manage the
ZyXEL Device.

interface(s) and from which IP address(es) users can use FTP to access the
ZyXEL Device.
• Use the SNMP screen (Section 20.5 on page 354) to configure your ZyXEL
Device’s settings for Simple Network Management Protocol management.
• Use the DNS screen (Section 20.6 on page 357) to configure through which
interface(s) and from which IP address(es) users can send DNS queries to the
ZyXEL Device.
• Use the ICMP screen (Section 20.7 on page 358) to set whether or not your
ZyXEL Device will respond to pings and probes for services that you have not
made available.
20.1.2 What You Need to Know About Remote Management
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 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.

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.
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.

20.5 The SNMP Screen
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.
Figure 210 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and
a manager.
354
P-2612HWU-F1 User’s Guide
Chapter 20 Remote Management Configuration
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 and node port status. 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.
Supported MIBs
The ZyXEL Device supports MIB II, which 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.
SNMP Traps
The ZyXEL Device will send traps to the SNMP manager when any one of the
following events occurs:
Table 117 SNMP Traps
TRAP #
TRAP NAME
DESCRIPTION
coldStart (defined in RFC1215)
A trap is sent after booting (power on).
warmStart (defined in RFC1215)
A trap is sent after booting (software reboot).
authenticationFailure (defined
in RFC-1215)
A trap is sent to the manager when receiving
any SNMP get or set requirements with the
wrong community (password).
whyReboot (defined in ZYXEL- A trap is sent with the reason of restart before
MIB)
rebooting when the system is going to restart
(warm start).

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.

Select WLAN to reply to incoming WLAN Ping requests.
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. If this option is not selected, 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 rule checks before reaching this anti-probing mechanism.
Therefore if a firewall rule stops a probing packet, the ZyXEL Device
reacts based on the firewall rule to either 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.

Universal Plug-and-Play (UPnP)
21.1 Overview
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.
21.1.1 What You Can Do in the UPnP Screen
Use the UPnP screen (Section 21.2 on page 363) to enable UPnP on the ZyXEL
Device and allow UPnP-enabled applications to automatically configure the ZyXEL
Device.
21.1.2 What You Need to Know About UPnP
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.
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
P-2612HWU-F1 User’s Guide
361
Chapter 21 Universal Plug-and-Play (UPnP)
Windows Messenger is an example of an application that supports NAT traversal
and UPnP.
See the NAT chapter for more information on NAT.
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.
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.

Select this check box to allow UPnP-enabled applications to
automatically configure the ZyXEL Device so that they can
communicate through the ZyXEL Device, for example by using
NAT traversal, UPnP applications automatically reserve a NAT
forwarding port in order to communicate with another UPnP
enabled device; this eliminates the need to manually configure
port forwarding for the UPnP enabled application.

Chapter 22 File Sharing
22.1.2 What You Need to Know About File-Sharing
User Account
This gives you access to the file-sharing server. It includes your user name and
password.
Workgroup name
This is the name given to a set of computers that are connected on a network and
share resources such as a printer or files. Windows automatically assigns the
workgroup name when you set up a network.
Shares
When settings are set to default, each USB device connected to the ZyXEL Device
is given a folder, called a “share”. If a USB hard drive connected to the ZyXEL
Device has more than one partition, then each partition will be allocated a share.
You can also configure a “share” to be a sub-folder or file on the USB device.
File Systems
A file system is a way of storing and organizing files on your hard drive and
storage device. Often different operating systems such as Windows or Linux have
different file systems. The file-sharing feature on your ZyXEL Device supports File
Allocation Table (FAT) and FAT32 file systems.
Common Internet File System
The ZyXEL Device uses Common Internet File System (CIFS) protocol for its file
sharing functions. CIFS compatible computers can access the USB file storage
devices connected to the ZyXEL Device. CIFS protocol is supported on Microsoft
Windows, Linux Samba and other operating systems (refer to your systems
specifications for CIFS compatibility).
File Transfer Protocol
This is a method of transferring data from one computer to another over a
network such as the Internet.
22.1.3 Before You Begin
Make sure the ZyXEL Device is connected to your network and turned on.
376
P-2612HWU-F1 User’s Guide
Chapter 22 File Sharing
Connect the USB device to one of the ZyXEL Device’s USB ports. Make sure the
ZyXEL Device is connected to your network.
The ZyXEL Device detects the USB device and makes its contents available for
browsing. If you are connecting a USB hard drive that comes with an external
power supply, make sure it is connected to an appropriate power source that is on.
Note: If your USB device cannot be detected by ZyXEL Device, see the
troubleshooting for suggestions.

Sharing a USB Printer
This chapter describes how you can share a USB printer via your ZyXEL Device.
23.1 Overview
The ZyXEL Device allows you to share a USB printer on your LAN. You can do this
by connecting a USB printer to one of the USB ports on the ZyXEL Device and then
configuring a TCP/IP port on the computers connected to your network.
Figure 244 Sharing a USB Printer
23.1.1 What You Need to Know About Printer Sharing
Print Server
This is a computer or other device which manages one or more printers, and
which sends print jobs to each printer from the computer itself or other devices.
Operating System
An operating system (OS) is the interface which helps you manage a computer.
Common examples are Microsoft Windows, Mac OS or Linux.
P-2612HWU-F1 User’s Guide
389
Chapter 23 Sharing a USB Printer
TCP/IP
TCP/IP (Transmission Control Protocol/ Internet Protocol) is a set of
communications protocols that most of the Internet runs on.
Port
A port maps a network service such as http to a process running on your
computer, such as a process run by your web browser. When traffic from the
Internet is received on your computer, the port number is used to identify which
process running on your computer it is intended for.
Line Printer Remote Protocol
The Line Printer Remote (LPR) Protocol is software that provides printer spooling
and print-server features using TCP/IP to connect printers and computers on a
network.
Supported OSs
Your operating system must support TCP/IP ports for printing and be compatible
with the LPR protocol.
The following OSs support ZyXEL Device’s printer sharing feature.
• Microsoft Windows 95, Windows 98 SE (Second Edition), Windows Me, Windows
NT 4.0, Windows 2000, Windows XP or Macintosh OS X.
23.1.2 Before You Begin
To configure the print server you need the following:
• Your ZyXEL Device must be connected to your computer and any other devices
on your network. The USB printer must be connected to your ZyXEL Device.
• A USB printer with the driver already installed on your computer.
• The computers on your network must have the printer software already installed
before they can create a TCP/IP port for printing via the network. Follow your
printer manufacturers instructions on how to install the printer software on your
computer.
Note: Your printer’s installation instructions may ask that you connect the printer to
your computer. Connect your printer to the ZyXEL Device instead.
23.1.3 What You Can Do with Printer Sharing

Configure a TCP/IP Printer Port
This example shows how you can configure a TCP/IP printer port. This example is
done using the Windows 2000 Professional operating system. Some menu items
may look different on your operating system. The TCP/IP port must be configured
with the IP address of the ZyXEL Device and must use the LPR protocol to
communicate with the printer. Consult your operating systems documentation for
instructions on how to do this or follow the instructions below if you have a
Windows 2000/XP operating system.
Click Start > Settings, then right click on Printers and select Open.

24.1 Overview
This chapter shows you how to configure system related settings, such as system
time, password, name, the domain name and the inactivity timeout interval.
24.1.1 What You Can Do in the System Settings Screens
• Use the General screen (Section 24.2 on page 412) to configure system
settings.
• Use the Time Setting screen (Section 24.3 on page 414) to set the system
time.
24.1.2 What You Need to Know About System Settings
Domain Name
This is a network address that identifies the owner of a network connection. For
example, in the network address “www.zyxel.com/support/files”, the domain
name is “www.zyxel.com”.
DHCP
DHCP (Dynamic Host Configuration Protocol) is a method of allocating IP
addresses to devices on a network from a DHCP Server. Often your ISP or a router
on your network performs this function.
LAN
A LAN (local area network) is typically a network which covers a small area, made
up of computers and other devices which share resources such as Internet access
and printers.

24.2 The General Screen
Use the General screen to configure system settings such as the system and
domain name, inactivity timeout interval and system password.
The System Name is for identification purposes. However, because some ISPs
check this name you should enter your computer's "Computer Name". Find the
system name of your Windows computer by following one of the steps below.
• In Windows XP, click start, My Computer, View system information and
then click the Computer Name tab. Note the entry in the Full computer
name field and enter it as the ZyXEL Device System Name.

Get from Time
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 sends when you
turn on the ZyXEL Device. 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.
Time Zone Setup
Time Zone
Choose the time zone of your location. This will set the time difference
between your time zone and Greenwich Mean Time (GMT).
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 Daylight Savings. 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
second Sunday of March. 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 Second, Sunday, March 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).

Here are a couple of examples:
Daylight Saving Time ends in the United States on the first Sunday of
November. 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

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 same moment (1 A.M. GMT or UTC). So in

Logs
25.1 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.
25.1.1 What You Can Do in the Log Screens
• Use the View Log screen (Section 25.2 on page 417) to see the logs for the
categories that you selected in the Log Settings screen.
• Use The Log Settings screen (Section 25.3 on page 418) to configure to where
the ZyXEL Device is to send logs; the schedule for when the ZyXEL Device is to
send the logs and which logs and/or immediate alerts the ZyXEL Device is to
record.
25.1.2 What You Need To Know About Logs
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.
25.2 The View Log Screen
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 25.3 on page 418).

CHAPTER
27
Tools
Do not interrupt the file transfer process as this may
PERMANENTLY DAMAGE your ZyXEL Device.
27.1 Overview
Use the instructions in this chapter to change the device’s configuration file or
upgrade its firmware. After you configure your device, you can backup the
configuration file to a computer. That way if you later misconfigure the device, you
can upload the backed up configuration file to return to your previous settings.
You can alternately upload the factory default configuration file if you want to
return the device to the original default settings. The firmware determines the
device’s available features and functionality. You can download new firmware
releases from your nearest ZyXEL FTP site (or www.zyxel.com) to use to upgrade
your device’s performance.
Only use firmware for your device’s specific model. Refer to the
label on the bottom of your ZyXEL Device.
27.1.1 What You Can Do in the Tool Screens
• Use the Firmware Upgrade screen (Section 27.2 on page 446) to upload
firmware to your device.
• Use the Configuration screen (Section 27.3 on page 449) to backup and
restore device configurations. You can also reset your device settings back to
the factory default.
• Use the Restart screen (Section 27.4 on page 452) to restart your ZyXEL
device.
27.1.2 What You Need To Know About Tools
Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory
default settings in the menus such as password, DHCP Setup, and TCP/IP Setup. It
P-2612HWU-F1 User’s Guide
439
Chapter 27 Tools
arrives from ZyXEL with a “rom” filename extension. Once you have customized
the ZyXEL Device's settings, they can be saved back to your computer under a
filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file)
is the system firmware and has a “bin” filename extension. Find this firmware at
www.zyxel.com.With many FTP and TFTP clients, the filenames are similar to
those seen next.
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file
"firmware.bin" to the ZyXEL Device.
ftp> get rom-0 config.cfg
This is a sample FTP session saving the current configuration to the computer file
“config.cfg”.
If your (T)FTP client does not allow you to have a destination filename different
than the source, you will need to rename them as the ZyXEL Device only
recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for
later use.
The following table is a summary. Please note that the internal filename refers to
the filename on the ZyXEL Device and the external filename refers to the filename
not on the ZyXEL Device, that is, on your computer, local network or FTP site and
so the name (but not the extension) may vary. After uploading new firmware, see
the Status screen to confirm that you have uploaded the correct firmware
version.

The firewall is active (turn the firewall off or create a firewall rule to allow access
from the WAN).
You have disabled the FTP service in the Remote Management screen.
The IP you entered in the Secured Client IP field does not match the client IP. If it
does not match, the device will disallow the FTP session immediately.
27.1.3 Before You Begin
• Ensure you have either created a firewall rule to allow access from the WAN or
turned the firewall off, otherwise the FTP will not function.
• Make sure the FTP service has not been disabled in the Remote Management
screen.
27.1.4 Tool Examples
Using FTP or TFTP to Restore Configuration
This example shows you how to restore a previously saved configuration. Note
that this function erases the current configuration before restoring a previous back
up configuration; please do not attempt to restore unless you have a backup
configuration file stored on disk.
FTP is the preferred method for restoring your current computer configuration to
your device since FTP is faster. Please note that you must wait for the system to
automatically restart after the file transfer is complete.
Do not interrupt the file transfer process as this may
PERMANENTLY DAMAGE your device. When the Restore
Configuration process is complete, the device automatically
restarts.

FTP and TFTP Firmware and Configuration File Uploads
These examples show you how to upload firmware and configuration files.
Do not interrupt the file transfer process as this may
PERMANENTLY DAMAGE your device.
FTP is the preferred method for uploading the firmware and configuration. To use
this feature, your computer must have an FTP client. The following sections give
examples of how to upload the firmware and the configuration files.
FTP File Upload Command from the DOS Prompt Example
Launch the FTP client on your computer.
Enter “open”, followed by a space and the IP address of your device.
Press [ENTER] when prompted for a username.
Enter your password as requested (the default is “1234”).
Enter “bin” to set transfer mode to binary.
Use “put” to transfer files from the computer to the device, for example, “put
firmware.bin ras” transfers the firmware on your computer (firmware.bin) to the
device and renames it “ras”. Similarly, “put config.rom rom-0” transfers the
configuration file on your computer (config.rom) to the device and renames it
“rom-0”. Likewise “get rom-0 config.rom” transfers the configuration file on the
device to your computer and renames it “config.rom.” See earlier in this chapter
for more information on filename conventions.
Enter “quit” to exit the ftp prompt.

More commands (found in GUI-based FTP clients) are listed in this chapter.
Refer to Section 27.1.2 on page 439 to read about configurations that disallow
TFTP and FTP over WAN.
TFTP File Upload
The device also supports the uploading of firmware files using TFTP (Trivial File
Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not
recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To transfer
the firmware and the configuration file, follow the procedure shown next.
Use telnet from your computer to connect to the device and log in. Because TFTP
does not have any security checks, the device records the IP address of the telnet
client and accepts TFTP requests only from this address.
Enter the command “sys stdio 0” to disable the management idle timeout, so the
TFTP transfer will not be interrupted. Enter “command sys stdio 5” to restore the
five-minute management idle timeout (default) when the file transfer is complete.
Launch the TFTP client on your computer and connect to the device. Set the
transfer mode to binary before starting data transfer.
Use the TFTP client (see the example below) to transfer files between the device
and the computer. The file name for the firmware is “ras”.
Note that the telnet connection must be active and the device in CI mode before
and during the TFTP transfer. For details on TFTP commands (see following
example), please consult the documentation of your TFTP client program. For
UNIX, use “get” to transfer from the device to the computer, “put” the other way
around, and “binary” to set binary transfer mode.
TFTP Upload Command Example
The following is an example TFTP command:
tftp [-i] host put firmware.bin ras
Where “i” specifies binary image transfer mode (use this mode when transferring
binary files), “host” is the device’s IP address, “put” transfers the file source on
the computer (firmware.bin – name of the firmware on the computer) to the file
destination on the remote host (ras - name of the firmware on the device).
Commands that you may see in GUI-based TFTP clients are listed earlier in this
chapter.

Enter your password as requested (the default is “1234”).
Enter “bin” to set transfer mode to binary.
Use “get” to transfer files from the ZyXEL Device to the computer, for example,
“get rom-0 config.rom” transfers the configuration file on the ZyXEL Device to
your computer and renames it “config.rom”. See earlier in this chapter for more
information on filename conventions.
Enter “quit” to exit the ftp prompt.
