What You Need To Know
The information in this section can help you configure the screens for your WAN
connection, as well as enable/disable some advanced features of your NBG4604.
7.3.1
Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower
layer protocol. To set up a WAN connection to the Internet, you need to use the
same encapsulation method used by your ISP (Internet Service Provider). If your
ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP
(Point-to-Point Tunneling Protocol), they should also provide a username and
password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the NBG4604, which makes it accessible
from an outside network. It is used by the NBG4604 to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the NBG4604 tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the
subnet mask and DNS server IP address(es) (and a gateway IP address if you use
the Ethernet or ENET ENCAP encapsulation method).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP
address and vice versa, for instance, the IP address of www.zyxel.com is
204.217.0.2. The DNS server is extremely important because without it, you must
know the IP address of a computer before you can access it.
The NBG4604 can get the DNS server addresses in the following ways.
1
The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP gives you DNS server addresses, manually
enter them in the DNS server fields.
2
If your ISP dynamically assigns the DNS server IP addresses (along with the
NBG4604’s WAN IP address), set the DNS server fields to get the DNS server
address from the ISP.

WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by
either using the factory default or cloning the MAC address from a computer on
your LAN. Choose
Factory Default
to select the factory assigned default MAC
Address.
Otherwise,
click
Clone the computer's MAC address - IP Address
and enter
the IP address of the computer on the LAN whose MAC you are cloning. Once it is
successfully configured, the address will be copied to configuration file. It is
recommended that you clone the MAC address prior to hooking up the WAN Port.
7.3.2
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
Figure 59
Multicast Example
In the multicast example above, systems A and D comprise one multicast group.
In multicasting, the server only needs to send one data stream and this is
delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group - it is not used to carry user data. The
NBG4604 supports both IGMP version 1 (
IGMP-v1
) and IGMP version 2 (
IGMP-
v2
).
At start up, the NBG4604 queries all directly connected networks to gather group
membership. After that, the NBG4604 periodically updates this information. IP
multicasting can be enabled/disabled on the NBG4604 LAN and/or WAN interfaces
in the Web Configurator (
LAN
;
WAN
). Select
None
to disable IP multicasting on
these interfaces.

7.3.3
NetBIOS over TCP/IP
NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets
that enable a computer to connect to and communicate with a LAN. For some dial-
up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
However it may sometimes be necessary to allow NetBIOS packets to pass
through to the WAN in order to find a computer on the WAN.
7.3.4
Auto-Bridge
In the rear panel of your NBG4604, you can see four LAN ports (1 to 4) and one
WAN port. The WAN port is for your Internet access connection, and the LAN ports
are for your network devices. The WAN port has a different IP address from the
LAN ports.
When you enable auto-bridging in your NBG4604, all five ports (4 LAN ports and
the WAN port) share the same IP address as shown in the figure below.
Figure 60
Autobridging Example
This might happen if you put the NBG4604 behind a NAT router that assigns it this
IP address. When the NBG4604 is in auto-bridge mode, the NBG4604 acts as an
AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this mode, your
NAT, DHCP server and firewall on the NBG4604 are not available. You do not have
to reconfigure them if you return to router mode.
Auto-bridging only works under the following conditions:
•
The WAN IP must be 192.168.x.y (where x and y must be from zero to nine). If
the LAN IP address and the WAN IP address are in the same subnet but
x or
y
is greater than nine, the device operates in router mode (with firewall
available).
•
The device must be in
Router Mode
(see
Chapter 21 on page 189
for more
information) for auto-bridging to become active.
IP Address: 192.168.1.20

7.4.2
PPPoE Encapsulation
The NBG4604 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an
IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with
a broadband modem (DSL, cable, wireless, etc.) connection. The
PPP over
Ethernet
option is for a dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that
works with existing access control systems (for example Radius).
IP Address
Enter your WAN IP address in this field if you selected
Use Fixed IP
Address
.
IP Subnet
Mask
Enter the
IP Subnet Mask
in this field.
Gateway IP
Address
Enter a
Gateway IP Address
(if your ISP gave you one) in this field.
DNS Servers
First DNS Server
Second DNS
Server
Select
From ISP
if your ISP dynamically assigns DNS server
information (and the NBG4604's WAN IP address). The field to the right
displays the (read-only) DNS server IP address that the ISP assigns.
Select
User-Defined
if you have the IP address of a DNS server. Enter
the DNS server's IP address in the field to the right. If you chose
User-
Defined
, but leave the IP address set to 0.0.0.0,
User-Defined
changes to
None
after you click
Apply
. If you set a second choice to
User-Defined
, and enter the same IP address, the second
User-
Defined
changes to
None
after you click
Apply
.
Select
None
if you do not want to configure DNS servers. If you do not
configure a DNS server, you must know the IP address of a computer in
order to access it.
WAN MAC
Address
The MAC address section allows users to configure the WAN port's MAC
address by either using the NBG4604’s MAC address, copying the MAC
address from a computer on your LAN or manually entering a MAC
address.
Factory default
Select
Factory default
to use the factory assigned default MAC
Address.
Clone the
computer’s MAC
address - IP
Address
Select
Clone the computer's MAC address - IP Address
and enter
the IP address of the computer on the LAN whose MAC you are cloning.
Once it is successfully configured, the address will be copied to the rom
file. It will not change unless you change the setting or upload a
different ROM file.
Set WAN MAC

Select this option and enter the MAC address you want to use.
Apply
Click
Apply
to save your changes back to the NBG4604.
