from behind the NAT firewall, then you can open the client up to unrestricted two-way
Internet access by defining a DMZ Host. The DMZ function allows you to re-direct all
packets going to your WAN port IP address to a particular IP address in your LAN. The
43
difference between the virtual server and the DMZ function is that the virtual server
re-directs a particular service/Internet application (e.g. FTP, websites) to a particular LAN
client/server, whereas DMZ re-directs all packets (regardless of services) going to your
WAN IP address to a particular LAN client/server.

Appendix A
How to Manually find your PC’s IP and MAC address
1) In Window’s open the Command Prompt program
2) Type ipconfig /all and <enter>
54
• Your PC’s IP address is the one entitled IP address (192.168.0.7)
• The router’s IP address is the one entitled Default Gateway (192.168.0.1)
• Your PC’s MAC Address is the one entitled Physical Address (00-48-54-12-41-44)
Glossary
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).
Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet for a
preconfigured amount of time, the connection will automatically be disconnected.
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.
55
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 forthe Internet router located at the ISP's office.
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 XRT-401E’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:
56
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.
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
graphicaluser 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.
