XRT-811 Features
XRT-811 incorporates many advanced features, carefully designed to provide sophisticated
functions while being easy to use.
Internet Access Features
• Shared Internet Access. All users on the LAN or WLAN can access the Internet
through XRT-811, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address
Translation).
• DSL & Cable Modem Support. XRT-811 has a 10/100M Ethernet port for connecting
a DSL or Cable Modem. All popular DSL and Cable Modems are supported. SingTel RAS
and Big Pond (Australia) login support is also included.
• PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN
port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Direct Connection" type
services.
• Fixed or Dynamic IP Address. On the Internet (WAN port) connection, XRT-811
supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP
Address.

XRT-811 User’s Manual
Advanced Internet Functions
• Communication Applications. Support for Internet communication applications, such
as interactive Games, Telephony, and Conferencing applications, which are often difficult
to use when behind a Firewall, is included.
• Special Internet Applications. Applications which use non-standard connections or
port numbers are normally blocked by the Firewall. The ability to define and allow such
applications is provided, to enable such applications to be used normally.
• Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
• DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way
communication with Servers or individual users on the Internet. This provides the ability to
run programs, which are incompatible with Firewalls.
• URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
• Internet Access Log. See which Internet connections have been made.
• VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
• DHCP Server Support.Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. XRT-811 can act as a DHCP Server for
devices on your local LAN and WLAN.
• Multi Segment LAN Support. LANs containing one or more segments are supported,
via XRT-811's RIP (Routing Information Protocol) support and built-in static routing table.
Network Printer
• Shared Printer (Network Printer). A printer connected to XRT-811's parallel port can
be shared by all PCs on the LAN or WLAN.
• Multiple OS Support. Clients may use any of the following operating systems:
• Windows 95/98/ME
• Windows NT 4.0, 2000, or XP.
• Unix
• Multi-protocol Support. The following printing methods are supported:
• Windows peer-to-peer printing over TCP/IP, using the supplied port driver.
• Windows LPD printing, using a Windows Server running NT 4.0 or Windows 2000
Server. In this situation, no software needs to be installed on the client PCs.
• Unix LPD printing. No additional software needs to be installed.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-
ration.
• Remote Management. XRT-811 can be managed from any PC on your LAN. And, if
the Internet connection exists, it can also (optionally) be configured via the Internet.
• UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and con-
figuration of XRT-811. UPnP is by supported by Windows ME, XP, or later.

Introduction
Security Features
• Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
• NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology is that by allowing all LAN users to share a single IP address, the location and even
the existence of each PC is hidden. From the external viewpoint, there is no network, only
a single device - XRT-811.
• Stateful Inspection Firewall. All incoming data packets are monitored and all incom-
ing server requests are filtered, thus protecting your network from malicious attacks from
external sources.
• Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much bandwidth
and so many resources that Internet access becomes unavailable. XRT-811 incorporates
protection against DoS attacks.
Package Contents
The following items should be included:
• XRT-811 Unit

The default value 255.255.255.0 is standard for small (class "C")
networks. For other networks, use the Subnet Mask for the LAN
segment to which XRT-811 is attached (the same value as the PCs on
that LAN segment).
• If Enabled, XRT-811 will allocate IP Addresses to PCs (DHCP
clients) on your LAN when they start up. The default (and recommended) value is Enabled.
• If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-configured to
treat XRT-811 as the default Gateway. See the following section
for further details.
• The Start IP Address and Finish IP Address fields set the values
used by the DHCP server when allocating IP Addresses to DHCP
clients. This range also determines the number of DHCP clients
supported.

DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a
DHCP Client (PC or device) upon request.
• The client request is made when the client device starts up (boots).
• The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
• XRT-811 can act as a DHCP server.
• Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client.
This is the default Windows setting for the TCP/IP network protocol. However, Windows
uses the term Obtain an IP Address automatically instead of "DHCP Client".
• You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your
LAN does not have other Routers, this means there must only be one (1) DHCP Server on
your LAN.)
Using XRT-811's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this screen,
you can:
• Enable or Disable XRT-811's DHCP Server function.
• Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices
iNote
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP
Server, rather than XRT-811's, the following procedure is required.
1. Disable the DHCP Server feature in XRT-811. This setting is on the LAN screen.
2. Configure the DHCP Server to provide XRT-811's IP Address as the Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 95/98/ME.
See Chapter 4 - Client Configuration for the procedure to check these settings.

PC Configuration
This Chapter details the PC Configuration required on the local ("Internal")
LAN.
Overview
For each PC, the following may need to be configured:
• TCP/IP network settings
• Internet Access configuration
• Printer configuration
Windows Clients
This section describes how to configure Windows clients for:
• Internet access via XRT-811
• Sharing the Printer connected to XRT-811.
The first step is to check the PC's TCP/IP settings.
XRT-811 uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP
protocol be installed and configured on each PC.
TCP/IP Settings - Overview
If using the default Broadband Router settings, and the default Windows
TCP/IP settings, no changes need to be made.
• By default, XRT-811 will act as a DHCP Server, automatically providing a suitable IP
Address (and related information) to each PC when the PC boots.
• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP
client.
If using a Fixed (specified) IP address, the following changes are required:
• The Gateway must be set to the IP address of XRT-811
• The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
iNote
configure the Router itself. Refer to Chapter 8 - Advanced
Setup for details.

Printer Setup for Windows
XRT-811 provides printing support for 2 methods for printing from Windows:
• Print Port Driver. After installing the Print Port Driver, Windows users can print directly
to XRT-811. Print jobs are spooled (queued) on each PC.
The supplied Print Port Driver supports Windows 95/98, Windows ME, Windows NT4.0,
Windows 2000 and Windows XP.
• LPD/LPR Printing. If using Windows NT 4.0 Server or Windows 2000 Server,
LPD/LPR printing can be used. No software needs to be installed on either the Windows
Server or each client PC. Print jobs will be spooled (queued) on the Windows Server, and
can be managed using the standard Windows Server tools.
Print Port Driver Setup
The following procedure is for all versions of Windows (95/98/ME, NT4.0, 2000, XP). The
Windows "Add Printer" screens will vary depending on your version or Windows, but the

Communication Applications
Most applications are supported transparently by XRT-811. But sometimes it is not clear which
PC should receive an incoming connection. This problem could arise with the Communication Applications listed on this screen.
If this problem arises, you can use this screen to set which PC should receive an incoming
connection, as described below.
Communication Applications
Select an Application
Send incoming calls to
This lists applications, which may generate incoming connections,
where the destination PC (on your local LAN) is unknown.
This lists the PCs on your LAN.
• If necessary, you can add PCs manually, using the "PC
Database" option on the advanced menu.
• For each application listed above, you can choose a destina-
tion PC.
• There is no need to "Save" after each change; you can set the
destination PC for each application, then click "Save".
Special Applications
If you use Internet applications, which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by XRT-811's firewall. In this
case, you can define the application as a "Special Application".
Special Applications Screen
This screen can be reached by clicking the Special Applications button on the Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the
client (PC) viewpoint

from the special application or service. (Note: Some applications use
different protocols for outgoing and incoming data).
• Start - Enter the beginning of the range of port numbers used by the
application server, for data you receive. If the application uses a single
port number, enter it in both the "Start" and "Finish" fields.
• Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you receive.
• Type - Select the protocol (TCP or UDP) used when you send data to
the remote system or service.
• Start - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a single
port number, enter it in both the "Start" and "Finish" fields.
• Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you send to it. If the application uses a single port
number, enter it in both the "Start" and "Finish" fields.
Using a Special Application
• Configure the Special Applications screen as required.
• On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Special
Application. The "Time-out" period may be up to 3 minutes.
If an application still cannot function correctly,
iNote
try using the "DMZ" feature.
DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the
Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet
users or Servers.
• This allows almost any application to be used on the "DMZ PC".
• The "DMZ PC" will receive all "Unknown" connections and data.

Dynamic DNS (Dynamic Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your
IP address may change whenever you connect, which makes it difficult to connect to you.
The Service works as follows:
1. You must register for the service at http://www.dyndns.org (Registration is free). Your
password will be E-mailed to you.
2. After registration, use the "Create New Host" option (at www.dyndns.org) to request your
desired Domain name.
3. Enter your data from www.dyndns.org in XRT-811 's DDNS screen.
4. XRT-811 will then automatically ensure that your current IP Address is recorded at
http://www.dyndns.org
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using
your Domain name, as shown on this screen.

XRT-811 User’s Manual
Virtual Servers
This feature allows you to make Servers on your LAN accessible to Internet users. Normally,
Internet users would not be able to access a server on your LAN because:
• Your Server does not have a valid external IP Address.
• Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
Figure 35: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Address, but
using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your
Virtual Servers using a URL, instead of an IP Address.

Firewall Rules
For normal operation and LAN protection, it is not necessary to use this screen.
The Firewall will always block DoS (Denial of Service) attacks. A DoS attack does not attempt
to steal data or damage your PCs, but overloads your Internet connection so you can not use it the service is unavailable.
As well, you can use this screen to create Firewall rules to block or allow specific traffic. But
Incorrect configuration may cause serious problems.
This feature is for advanced administrators only!

Click the Firewall Rules option on the Security menu to see a screen like the following example.
This example contains two (2) rules for outgoing traffic.
Since the default rule for outgoing (LAN => WAN) traffic is "Allow",

Note:
• A DoS attack does not attempt to steal data or damage your PCs,
but overloads your Internet connection so you can not use it - the

• This device uses "Stateful Inspection" technology. This system can
detect situations where individual TCP/IP packets are valid, but
collectively they become a DoS attack.
This setting affects the number of "half-open" connections allowed.
• A "half-open" connection arises when a remote client contacts the
Server with a connection request, but then does not reply to the
Server's response.
• While the optimum number of "half-open" connections allowed

You must use this IP Address to connect (see below).
This IP Address is allocated by your ISP. But if using a Dynamic IP
Address, this value can change each time you connect to your ISP. So
it is better if your ISP allocates you a Fixed IP Address.
To connect from a remote PC via the Internet
1. Ensure your Internet connection is established, and start your Web Browser.
2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of XRT-811. If
the port number is not 80, the port number is also required. (After the IP Address, enter ":"
followed by the port number.)
e.g.
HTTP://123.123.123.123:8080
This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.

Routing
Overview
• If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
• If XRT-811 is only acting as a Gateway for the local LAN segment, ignore the "Routing"
page even if your LAN has other Routers.
• If your LAN has a standard Router (e.g. Cisco) on your LAN, and XRT-811 is to act as a
Gateway for all LAN segments, enable RIP (Routing Information Protocol) and ignore the
Static Routing table.
• If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure
the Static Routing table instead. (You also need to configure the other Routers.)
• If using Windows 2000 Data center Server as a software Router, enable RIP on XRT-811,
and ensure the following Windows 2000 settings are correct:
• Open Routing and Remote Access
• In the console tree, select Routing and Remote Access , [server name], IP Routing,
RIP
• In the "Details" pane, right-click the interface you want to configure for RIP version 2,
and then click "Properties".
• On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and
Incoming packet protocol to "RIP version 1 and 2".
Routing Screen
The routing table is accessed by the Routing link on the Advanced screen.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table,
as explained above, although is it possible to use both methods simultaneously.
Static Routing Table
• If RIP is not used, an entry in the routing table is required for each LAN segment on your
Network, other than the segment to which this device is attached.
• The other Routers must also be configured. See Configuring Other Routers on your LAN

Configuring Other Routers on your LAN
It is essential that all IP packets for devices not on the local LAN be passed to XRT-811, so
that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local
LAN must be configured to use XRT-811 as the Default Route or Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as XRT-811. This router
requires that the Default Route is XRT-811 itself. Typically, routers have a special entry for the
Default Route. It should be configured as follows.
Destination IP Address
Network Mask
Gateway IP Address
Metric
Normally 0.0.0.0, but check your router documentation.
Normally 0.0.0.0, but check your router documentation.
The IP Address of XRT-811.

Other Routers on the Local LAN
Other routers on the local LAN must use XRT-811's Local Router as the Default Route. The
entries will be the same as XRT-811's local router, with the exception of the Gateway IP Address.
• For a router with a direct connection to XRT-811's local Router, the Gateway IP Address
is the address of XRT-811's local router.
• For routers which must forward packets to another router before reaching XRT-811's local
router, the Gateway IP Address is the address of the intermediate router.

Appendix A
Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using XRT-811
and some possible solutions to them. If you follow the suggested steps and XRT-811 still does
not function properly, contact your dealer for further advice.
General Problems
Problem 1: Can't connect to XRT-811 to configure it.
Solution 1:
Check the following:
• XRT-811 is properly installed, LAN connections are OK, and it is
powered ON.
• Ensure that your PC and XRT-811 are on the same network segment. (If
you don't have a router, this must be the case.)
• If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
• If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with XRT-811's default IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match XRT-
811.
In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.
Internet Access
Problem 1:When I enter a URL or IP address I get a time out error.
Solution 1:
A number of things could be causing this. Try the following troubleshooting
steps.
• Check if other PCs work. If they do, ensure that your PCs IP settings are
correct. If using a Fixed (Static) IP Address, check the Network Mask,
Default gateway and DNS as well as the IP Address.
• If the PCs are configured correctly, but still not working, check XRT-
811. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
• If XRT-811 is configured correctly, check your Internet connection
(DSL/Cable modem etc) to see that it is working correctly.
Problem 2: Some applications do not run properly when using XRT-811.
Solution 2:
XRT-811 processes the data passing through it, so it is not transparent.
Use the Special Applications feature to allow the use of Internet applications

which do not function correctly.
If this does solve the problem you can use the DMZ function. This should
work with almost every application, but:
• It is a security risk, since the firewall is disabled.
• Only one (1) PC can use this feature.
Printing
Problem 1:When I tried to install the Printing software for Peer-to-Peer printing,
I received an error message and the installation was aborted..
Solution 1:
Problem 2:I am using Windows 95, and the Printing software installed and ran,
Solution 2:
This may be caused by an existing installation of the printer port software.
Before attempting another installation:
• Remove the existing installation
• Restart your PC
To remove an existing printer port installation:
1. Open Start - Settings - Control Panel - Add/Remove Programs
2. Look for an entry with a name like "Shared Port", "Shared Printer
Port", "Print Server Driver" or "Print Server Port".
3. Select this item, click "Add/Remove", and confirm the deletion.

XRT-811 User’s Manual
Glossary
Bridge: A bridge is an intelligent, internetworking device that forwards or filters packets
between different networks based on data link layer (MAC) address information.
Default Gateway (Router): Every non-router IP device needs to configure a default gateway’s
IP address. When the device sends out an IP packet, if the destination is not on the same network, the device has to send the packet to its default gateway, which will then send it out
towards the destination.
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives every computer on your home network an IP address.
DNS Server IP Address: DNS stands for Domain Name System, which allows Internet servers
to have a domain name (such as www.Broadbandrouter.com) and one or more IP addresses
(such as 192.34.45.8). A DNS server keeps a database of Internet servers and their respective
domain names and IP addresses, so that when a domain name is requested (as in typing
"www.planet.com.tw" into your Internet browser), the user is sent to the proper IP address. The
DNS server IP address used by the computers on your home network is the location of the DNS
server your ISP has assigned to you.
DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your existing
phone lines to transmit data at high speeds.
Ethernet: A standard for computer networks. Ethernet networks are connected by special
cables and hubs, and move data around at up to 10/100 million bits per second (Mbps).
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP address
consists of a series of four numbers separated by periods, that identifies a single, unique Internet computer host in an IP network. Example: 192.168.0.1. It consists of 2 portions: the IP
network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded decimal
numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything from 000 to 255,
or as four cascaded binary numbers separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb,
where each “b” can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive leading
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be
described simply as “x” number of leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP address that
correspond to 1’s in the network mask become part of the IP network address, and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, and its host ID is,
00000000.00000000.00000000.00000111 . This is a convenient and efficient method for
routers to route IP packets to their destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP address for
the Internet router located at the ISP's office.
90
Appendix A - Troubleshooting
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected together in
a relatively small area (such as a house or an office). Your home network is considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the hardware
address of a device connected to a network. The MAC address is a unique identifier for a
device with an Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds
to the Manufacturer ID (unique for each manufacturer), plus 3 bytes that are often used as the
product’s serial number.
NAT: Network Address Translation. This process allows all of the computers on your home
network to use one IP address. Using the broadband router’s NAT capability, you can access
the Internet from any computer on your home network without having to purchase more IP
addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network application/protocol over another. Below is a list of common applications and protocol/port numbers:
Application Protocol Port Number
Telnet TCP 23
FTP TCP 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
SNMP UCP 161
SNMP Trap UDP 162
HTTP TCP 80
PPTP TCP 1723
PC Anywhere TCP 5631
PC Anywhere UDP 5632
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data transmission method originally created for dial-up connections; PPPoE is for Ethernet connections.
PPPoE relies on two widely accepted standards, Ethernet and the Point-to-Point Protocol. It is a
communications protocol for transmitting information over Ethernet between different manufacturers
Protocol: A protocol is a set of rules for interaction agreed upon between multiple parties so
that when they interface with each other based on such a protocol, the interpretation of their
behavior is well defined and can be made objectively, without confusion or misunderstanding.
Router: A router is an intelligent network device that forwards packets between different
networks based on network layer address information such as IP addresses.
91
XRT-811 User’s Manual
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided by
your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used
to create IP address numbers used only within a particular network (as opposed to valid IP
address numbers recognized by the Internet, which must be assigned by InterNIC).
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable
Datagram Protocol (UDP). TCP/IP is the standard protocol for data transmission over the
Internet. Both TCP and UDP are transport layer protocol. TCP performs proper error detection
and error recovery, and thus is reliable. UDP on the other hand is not reliable. They both run on
top of the IP (Internet Protocol), a network layer protocol.
WAN: Wide Area Network. A network that connects computers located in geographically
separate areas (e.g. different buildings, cities, countries). The Internet is a wide area network.
Web-based management Graphical User Interface (GUI): Many devices support a graphical
user interface that is based on the web browser. This means the user can use the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the device being managed.
