nISP Name, Host Name, Gateway, DNS1 and DNS2 Address, DNS
Domain Name
Those information are provided by your ISP company.
nMTU(Maximum Transmission Unit)
This defines the maximum size of the packets sent from your computer
onto the network. Any messages larger than the MTU are divided into
smaller packets before being sent. Leave this on the default value(1500)
unless you have a particular reason to change it.
nNAT Setup
The Internet is expanding at an exponential rate. As the amount of
information and resources increases, it is becoming a requirement for even
the smallest businesses and homes to connect to the Internet. Network
Address Translation (NAT) is a method of connecting multiple computers
to the Internet (or any other IP network) using one IP address. This allows
home users and small businesses to connect their network to the Internet
cheaply and efficiently.
Universal Plug and Play (UPnP) is an architecture for pervasive peer-to-
peer network connectivity of PCs and intelligent devices or appliances,
particularly within the home. UPnP builds on Internet standards and
technologies, such as TCP/IP, HTTP, and XML, to enable these devices to
automatically connect with one another and work together to make
networking - particularly home networking - possible for more people.

GN-B46B Wireless Broadband Router User Guide
nSSID
The SSID is the name represent the router in the wireless network. This
SSID string is case sinsitive of up to 32 ASCII characters. The default
value is “GIGABYTE”, if the setup value is the default value, like “router”.
Only can accept the computer connection, which use the wireless card
SSID (or ESSID) set up, is “router”.
nRate
You can select one of the rates among 1M, 2M, 5.5M and 11M based on
your need. The default value is “auto/best”.
nHidden SSID
This setting allows you to hide the SSID in wireless transmission. Those
who don’t know the SSID will be able connect to the router. The default
value is “disable”.
nAuthentication Type
You may choose between “Open System”, “Shared Key”, and “Open
system & Shared Key”. The Authentication Type default is set to “Open
System”.
Open System, in which the sender and the recipient do NOT share a
secret key. Each party generates its own key-pair and asks the receiver to
accept the randomly generated key. Once accepted, this key is used for a
short time only. Then a new key is generated and agreed upon.
Shared Key is both the sender and the recipient share a secret key.
If the “Shared Key” option is selected, it will not be able to perform the
option “disable” of the WEP.
nWEP Key
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm, as described in the IEEE 802.1x
standard. When the “disable” is selected there is no WEP encryption.
When either “64bits” or “128bits” selected there is encrypted date transfer
to prevent unauthorized user to access the wireless network.
GN-B46B Wireless Broadband Router User Guide
49
There are two levels of encryption 64 bits and 128 bits. The 64 bits
encryption is referenced as a lower level encryption. The 128 bits
encryption is referenced as a higher level encryption.
64 (40) Bits WEP Key: xx-xx-xx-xx-xx
128 (104) bits WEP Key: xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx
The 64 bits WEP encryption use 40 bits as a secret key, which can
controlled by user, and 24 bits as the initialize vector, which user can not
control. These two portions plus together is 64 bits encryption. Some other
vendor’s product might refer as 40 bits encryption. It is the same thing.
The 128 bits WEP encryption use 104 bits as a secret key, which can
controlled by user, and 24 bits as the initialize vector, which user can not
control. These two portions plus together is 128 bits encryption. Some
other vendor’s product might refer as 104 bits encryption. It is the same
thing.
MAC Access Control
The MAC Access Control allows the router to define up to 32 hosts which are allowed to
access to the WAN port. To disable the MAC Access Control function, keep the default
value, Disable. To set up a MAC setting, click Enable.
50
GN-B46B Wireless Broadband Router User Guide
Static Routing Table
Under some of Internet environments, some of the subnet do not go through the default
gateway. Users can add those routing information to Static Routing Table themselves.
Verify the desired setting and then click the “Submit” button to set the value into GN-
B46B.
nDestination IP
The Destination IP address is the address of the network or host to which
the static route is assigned.
nNetmask
The Netmask determines which portion of a destination LAN IP address is
the network portion, and which portion is the host portion.
nGateway
This is the IP address of the gateway device that allows for contact
between the router and the network or host.
nMetric
Type a numeber between 1 and 15 as the Metric value. This represents
the number of routers between your network and the destination. Usually,
a setting of 2 or 3 works, but if this is a direct connection, set is to 1. The
default value is 1.

Virtual Server
DMZ
If you have a computer that cannot run an Internet application (e.g. internet game, vedio
conferencing, or VPN connections) properly from behind the NAT firewall, then you can
open the computer up to unrestricted two-way Internet access.To use the DMZ, you
have to set a static IP address for the computer. The IP Address (such as 192.168.1.1)
of the computer at the LAN terminal can be used to input to the field of LAN IP Address.
Verify the desired setting and then click the “Submit” button to set the value into GN-
B46B.
Virtual server setting split into two different case. Case 1 is router having only 1 global IP
address, PPPoE/DHCP/Static is this case. Case 2 is router having more than 1 global IP
address, normal having 8 or 16 IP address, PPPoE unnumbered is this case. In case 1,
virtual server only need to configure LAN host information, because WAN IP address
always the same, but in case 2, virtual server also need to configure which WAN IP ad-
dress need redirect to internal LAN host.
52
GN-B46B Wireless Broadband Router User Guide
PPPoE/DHCP/Static
Virtual Server provides a way to let the PC at the WAN end connect to a server of a PC
at the LAN end. Taking the IP address 192.168.1.1 of a PC on a FTP at the LAN for
example:
uProtocol: TCP
uPort: 21
uVitrual Server IP: 192.168.1.1
uEnable: enable
The PC at the WAN end can connect to the internal FTP server at the IP address
192.168.1.1 via the WAN end of the IP address of the FTP B46B.
GN-B46B Wireless Broadband Router User Guide
53
PPPoE Unnumber
The PPPoE Unnumer user may have multiple global IP addresses, therefore each IP
address needs to setup specifically.
Note: Your ISP may provides you a group of the Global IP,
e.g. 61.222.10.1 ~ 61.222.10.7(But only can use 61.222.10.2~61.222.10.6)
Taking the IP address 192.168.1.1 of a PC on a FTP at the LAN for example:
uGlobal IP: 61.222.10.2
uProtocol: TCP
uPort: 21
uVitrual Server IP: 192.168.1.1
uEnable: enable
The PC at the Global IP 61.222.10.2 can connect to the internal FTP server at the IP
address 192.168.1.1 via the WAN end of the IP address of the FTP GN-B46B.

VPN Pass Through
Virtual private networks (VPN)are secured private network connections, built on top of
publicly-accessible infrastructure, such as the Internet or the public telephone network.
VPNs typically employ some combination of encryption, digital certificates, strong user
authentication and access control to provide security to the traffic they carry. They usually
provide connectivity to many machines behind a gateway or firewall.
nPPTP Pass Through setting
PPTP stands for Point-to-Point Tunneling Protocol. It basically allows you to establish
a connection to a corporate network and you can share files and other data as if your
machine were actually on that local network.
nIPSec Pass Through setting
IPSec stands for IP Security. It provides authentication and encryption over the
Internet. It functions at Layer 3 and thus secures everything on the network. It has
become a standard protocol used for virtual private networks (VPNs).
GN-B46B supports Internet-industry standards technology to provide customers with open
interoperable VPN solutions such as Internet Protocol Security (IPSec) and Layer 2
Tunneling Protocol (L2TP) as well as Point-to-Point Tunneling Protocol (PPTP).
56
GN-B46B Wireless Broadband Router User Guide
Enable/Disable VPN pass through. If administrator configure a host to enable VPN pass
through, router will automatically setting virtual server and firewall setting for this host. All
VPN packets will be transparent and will redirect to this host. VPN pass through works,
either VPN server behind the LAN side or VPN server locate at WAN side. For different
VPN pass through setting, only 1 host can be configured as pass through.
nL2TP Pass Through setting
L2TP stands for Layer 2 Tunneling Protocol. It is an extension of the Point-to-Point
Tunneling Protocol and is also used to establish virtual private networks.

Appendix A: Glossary
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it needs to act
as a MDI or MDIX port. The auto-MDI/MDIX capability eliminates the need for crossover
cables.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that converts exist-
ing twisted-pair telephone lines into access paths for high-speed communications of vari-
ous sorts.
Auto-negotiate
To automatically determine the correct settings. The term is often used with communica-
tions and networking.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
the configuration of computers that use TCP/IP. DHCP can be used to automatically as-
sign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnet
mask and default router, and to provide other configuration information such as the ad-
dresses for printer, time and news servers.
DMZ
In computer networks, a DMZ (demilitarized zone) is a computer host or small network
inserted as a "neutral zone" between a company's private network and the outside public
network. It prevents outside users from getting direct access to a server that has company
data. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP
) servers, FTP servers, SMTP (e-mail) servers and DNS servers.
DNS
The Domain Name System (DNS) is a distributed Internet directory service. DNS is used
mostly to translate between domain names and IP addresses, and to control Internet email
delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be
located and email delivery stalls.
GN-B46B Wireless Broadband Router User Guide
69
Dynamic IP Address
An IP address that is automatically assigned to a client station in a TCP/IP network,
typically by a DHCP server.
Firewall
A system designed to prevent unauthorized access to or from a private network. Firewalls
can be implemented in both hardware and software, or a combination of both. Firewalls
are frequently used to prevent unauthorized Internet users from accessing private
networks connected to the Internet, especially intranets. All messages entering or leaving
the intranet pass through the firewall, which examines each message and blocks those
that do not meet the specified security criteria.
Gateway
A device, usually a router, that connects hosts on a local network to other networks.
IP Address
Every machine on the Internet has a unique identifying number, called an IP Address. A
typical IP address looks like this: 216.27.61.137
IPSec
IPSec stands for IP Security. It provides authentication and encryption over the Internet. It
functions at Layer 3 and thus secures everything on the network. It has become a
standard protocol used for virtual private networks (VPNs).
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access Control) address
is your computer's unique hardware number. Usually written in the form 01:23:45:67:89:
ab
MTU
The size in bytes of the largest packet that can be sent or received.
NAT
A technique by which several hosts share a single IP addree for access to the Internet.
Ping (Packet Internet Groper)
A utility to determine whether a specific IP address is accessible. It works by sending a
packet to the specified address and waiting for a reply. PING is used primarily to trouble-
shoot Internet connections.

SSID
The SSID is the name represent the router in the wireless network.
PPPoE
Point-to-Point over Ethernet is a protocol for connecting remote hosts to the Internet over
an always-on connection by simulating a dial-up connection.
Router
A device that forwards data packets along networks. A router is connected to at least two
networks, commonly two LANs or WANs or a LAN and its ISP’s network. Routers are
located at gateways, the places where two or more networks connect.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address has two
components, the network address and the host address. Subnetting enables the network
administrator to further divide the host part of the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of communications
protocols used to connect hosts on the Internet.
VPN
Virtual private networks are secured private network connections, built on top of publicly-
accessible infrastructure, such as the Internet or the public telephone network. VPNs
typically employ some combination of encryption, digital certificates, strong user
authentication and access control to provide security to the traffic they carry. They usually
provide connectivity to many machines behind a gateway or firewall.
WAN
Wide Area Network, a communication network that covers a relatively large geographic
area, consisting of two or more LANs. Broadband communication over the WAN is often
through public networks such as the ADSL or Cable systems, or through leased lines or
satellites. In its most basic definition, the Internet could be considered a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 64/128-bit shared
key algorithm, as described in the IEEE 802.11 standard.
