CHAPTER 1: Introduction
1.1 An Overview of WebShare 111/141 ADSL2+ Router
Welcome to the WebShare 111/141 ADSL2+ Router. Your WebShare 111/141
ADSL2+ Router is an “all-in-one” unit, combining an ADSL modem, ADSL router
and Ethernet network switch, providing everything you need to get the machines
on your network connected to the Internet over your ADSL broadband connection.
The WebShare 111/141 ADSL2+ Router complies with ADSL2+ standards for
worldwide deployment and supports downstream rates of up to 24 Mbps and
upstream rates of up to 1 Mbps. It is designed for small office, home office and
residential users, enabling even faster speed Internet connections. User can
enjoy ADSL services and broadband multimedia applications such as interactive
gaming, video streaming and real-time audio much easier and faster than ever
before.
The product supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) over
ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed),
PPP over Ethernet (RFC 2516), and IPoA (RFC1577) to establish a connection
with ISP. The product also supports VC-based and LLC-based multiplexing.
It is the perfect solution to connect a small group of PCs to a high-speed
broadband Internet connection. Multi-users can have high-speed Internet access
simultaneously.
This product also serves as an Internet firewall, protecting your network from
being accessed by outside users. Not only provide the natural firewall function
(Network Address Translation, NAT), it also provides rich firewall features to
secure user’s network. All incoming data packets are monitored and filtered.
Besides, it can also be configured to block internal users from accessing to the
Internet.
The product provides two levels of security support. First, it masks LAN users’ IP
addresses which are invisible to outside users on the Internet, making it much
more difficult for a hacker to target a machine on your network. Secondly, it can
block and redirect certain ports to limit the services that outside users can access.
For example, to ensure that games and other Internet applications will run
properly, user can open some specific ports for outside users to access internal
services in network.
Integrated DHCP (Dynamic Host Control Protocol) services, client and server,
allow multiple users to get their IP addresses automatically on boot up from the
product. Simply set local machines as a DHCP client to accept a dynamically
assigned IP address from DHCP server and reboot. Each time local machine is
powered up; the router will recognize it and assign an IP address to instantly
connect it to the LAN.
For advanced users, Virtual Service function allows the product to provide limited
visibility to local machines with specific services for outside users. An ISP
A02-RA111 / A02-RA141 Pag. 1
WebShare 111/141
(Internet Service Providers) provided IP address can be set to the product and
then specific services can be rerouted to specific computers on the local network.
For instance, a dedicated web server can be connected to the Internet via the
product and then incoming requests for HTML that are received by the product
can be rerouted to the dedicated local web server, even though the server now
has a different IP address. In this example, the product is on the Internet and
vulnerable to attacks, but the server is protected.
Virtual Server can also be used to re-task services to multiple servers. For
instance, the product can be set to allow separated FTP, Web, and Multiplayer
game servers to share the same Internet-visible IP address while still protecting
the servers and LAN users from hackers.

CHAPTER 3: Configuration
WebShare 111/141 Router ADSL2+ can be configured with your web browser. A
web browser is included as a standard application in the following operating
systems: Windows 98/NT/2000/XP/Me, MAC, Linux, etc. The product provides a
very easy and user-friendly interface for configuration.
3.1 Before Configuration
PCs must have an Ethernet interface installed properly and be connected to the
router either directly or through an external repeater hub, and have TCP/IP
installed and configured to obtain an IP address through a DHCP server or a fixed
IP address that must be in the same subnet as the router. The default IP address
of the router is 192.168.1.254 and the subnet mask is 255.255.255.0 (i.e. any
attached PC must be in the same subnet, and have an IP address in the range of
192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to
get an IP address automatically from the router using DHCP. If you encounter any
problems accessing the router’s web interface it may also be advisable to
uninstall any kind of software firewall on your PCs, as they can cause problems
accessing the 192.168.1.254 IP address of the router. Users should make their
own decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation. First
of all, please check your PC’s network components. The TCP/IP protocol stack
and Ethernet network adapter must be installed. If not, please refer to your
Windows-related or other operating system manuals.
Any TCP/IP capable workstation can be used to communicate
with or through the WebShare 111/141 ADSL2+ Router. To
configure other types of workstations, please consult the
manufacturer’s documentation.

CHAPTER 4: Quick Start
This chapter provides information on the Wizard Setup screens in the web
configurator.
4.1 Wizard Setup Introduction
Use the Wizard Setup screens to configure your system for Internet access
settings and fill in the fields with the information in the Internet Account
Information table of the Compact Guide or Read Me First. Your ISP may have
already configured some of the fields in the wizard screens for you.
4.2 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ADSL Router
supports the following methods.
4.2.1 PPP over Ethernet
PPPoE provides access control and billing functionality in a manner similar to
dial-up services using PPP. The ADSL Router bridges a PPP session over
Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC
(Permanent Virtual Circuit) which connects to ADSL Access Concentrator where
the PPP session terminates. One PVC can support any number of PPP sessions
from your LAN. For more information on PPPoE, see the appendix.
4.2.2 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). It
provides access control and billing functionality in a manner similar to dial-up
services using PPP. The ADSL Router encapsulates the PPP session based on
RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the
Internet Service Provider's (ISP) DSLAM (digital access multiplexer). Please refer
to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more
information on PPP.
4.2.3 RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM
Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple
protocols over a single ATM virtual circuit (LLC-based multiplexing) and the
second method assumes that each protocol is carried over a separate ATM virtual
circuit (VC-based multiplexing). Please refer to the RFC for more detailed
information.
A02-RA111 / A02-RA141 Pag. 25
WebShare 111/141
4.3 Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is
carrying. Be sure to use the multiplexing method required by your ISP.
4.3.1 VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific
virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be
dominant in environments where dynamic creation of large numbers of ATM VCs
is fast and economical.
4.3.2 LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information
being contained in each packet header. Despite the extra bandwidth and
processing overhead, this method may be advantageous if it is not practical to
have a separate VC for each carried protocol, for example, if charging heavily
depends on the number of simultaneous VCs.
4.4 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel
Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255
and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM
traffic). Please see the appendix for more information.
4.5 Quick Start
Following next steps you can make operating WebShare Router ADSL2+ in short
time using PCs in DHCP mode. Refer to manual on Installation CD if you need
personalized configuration.
Click on Quick Start then Run Wizard to perform an automatic protocol

Static IP address: this configuration is valid in case of a subscription with a
static IP.
PPPoE/PPPoA
PPPoE (PPP over Ethernet) is an ADSL connection known as dial-up DSL. As
the PPPoA it has been created to integrate large band services paying a
particular attention to an easy configuration. The user can obtain an high access
speed and he can also share the same account with the ISP. No additional
software are required. This configuration is valid in case of a subscription with a
A02-RA111 / A02-RA141 Pag. 27

static IP and active NAT (SUA) (for the managing of the public class turn to the
CD handbook). Let’s see how to configure correctly this kind of ADSL
configuration.
Insert Username and Password and make sure that the parameters are, in case
of PPPoA, the ones in the picture, if not specifically shown by the ISP.
In case of PPPoE choose Connection Type=PPPoE LLC.
Click on Next.
You have to pay particular attention to the WAN-ADSL
connection. If you have any doubt turn to qualified personnel or
contact Atlantis-Land technical assistance. Atlantis Land will not
be considered responsible in case of wrong or bad
configuration.
STATIC IP ADDRESS
This configuration is valid in case of a subscription with a static IP and active NAT
SUA (for the managing of the public class turn to the CD Manual). Make sure that
the parameters are, in case of RFC1483, the ones in the picture, if not
specifically shown by the ISP.
Insert then the public static IP address given by the ISP and choose Connection
Type=1483 Routed IP LLC(IPoA). Make sure that the parameters are, the ones

CHAPTER 5: LAN Setup
This chapter describes how to configure LAN settings.
5.1 LAN Overview
A Local Area Network (LAN) is a shared communication system to which many
computers are attached. A LAN is a computer network limited to the immediate
area, usually the same building or floor of a building.
The LAN screens can help you configure a LAN DHCP server and manage IP
addresses.
5.1.1 LANs, WANs and the ADSL Router
The actual physical connection determines whether the ADSL Router ports are
LAN or WAN ports. There are two separate IP networks, one inside, the LAN
network; the other outside: the WAN network as shown next:
A02-RA111 / A02-RA141 Pag. 30
WebShare 111/141
5.2 DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding
IP address and vice versa, for example, the IP address of www.atlantis-land.com
is 204.217.0.2. The DNS server is extremely important because without it, you
must know the IP address of a machine before you can access it. The DNS
server addresses that you enter in the DHCP setup are passed to the client
machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses. The first
is for an ISP to tell a customer the DNS server addresses, usually in the form of
an information sheet, when s/he signs up. If your ISP gives you the DNS server
addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave
them blank.
Some ISP’s choose to pass the DNS servers using the DNS server extensions of
PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give
you explicit DNS servers, chances are the DNS servers are conveyed through
IPCP negotiation. The ADSL Router supports the IPCP DNS server extensions
through the DNS proxy feature.
If the Primary and Secondary DNS Server fields in DHCP Setup are not specified,
for instance, left as 0.0.0.0, the ADSL Router tells the DHCP clients that it itself is
the DNS server. When a computer sends a DNS query to the ADSL Router, the
ADSL Router forwards the query to the real DNS server learned through IPCP
and relays the response back to the computer.
Please note that DNS proxy works only when the ISP uses the IPCP DNS server
extensions. It does not mean you can leave the DNS servers out of the DHCP
setup under all circumstances. If your ISP gives you explicit DNS servers, make
sure that you enter their IP addresses in the DHCP Setup menu. This way, the
ADSL Router can pass the DNS servers to the computers and the computers can
query the DNS server directly without the ADSL Router’s intervention.
5.3 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without
it, you must know the IP address of a computer before you can access it.
There are two ways that an ISP disseminates the DNS server addresses.
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, enter them in the DNS Server fields in DHCP Setup.
2. Leave the DNS Server fields in DHCP Setup blank (for example 0.0.0.0). The
ADSL Router acts as a DNS proxy when this field is blank.
5.4 LAN TCP/IP
The ADSL Router has built-in DHCP server capability that assigns IP addresses
and DNS servers to systems that support DHCP client capability.
A02-RA111 / A02-RA141 Pag. 31
WebShare 111/141
5.4.1 Factory LAN Defaults
The LAN parameters of the ADSL Router are preset in the factory with the
following values:
IP address of 192.168.1.254 with subnet mask of 255.255.255.0 (24 bits)
DHCP server enabled with 100 client IP addresses starting from 192.168.1.100.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), read the embedded web configurator help
regarding what fields need to be configured.
5.4.2 IP Address and Subnet Mask
Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for
this information.
5.4.3 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets. When set to:
1. Both - the ADSL Router will broadcast its routing table periodically and
incorporate the RIP information that it receives.
2. In Only - the ADSL Router will not send any RIP packets but will accept all RIP
packets received.
3. Out Only - the ADSL Router will send out RIP packets but will not accept any
RIP packets received.
4. None - the ADSL Router will not send any RIP packets and will ignore any RIP
packets received.
The Dynamic Route field controls the format and the broadcasting method of the
RIP packets that the ADSL Router sends (it recognizes both formats when
receiving). RIP-1 is universally supported; but RIP-2 carries more information.
RIP-1 is probably adequate for most networks, unless you have an unusual
network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
5.4.4 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.
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.
IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but
A02-RA111 / A02-RA141 Pag. 32
WebShare 111/141
IGMP version 1 is still in wide use. If you would like to read more detailed
information about interoperability between IGMP version 2 and version 1, please
see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host
groups and can be in the range 224.0.0.0 to 239.255.255.255. The address
224.0.0.0 is not assigned to any group and is used by IP multicast computers.
The address 224.0.0.1 is used for query messages and is assigned to the
permanent group of all IP hosts (including gateways). All hosts must join the
224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is
assigned to the multicast routers group.
The ADSL Router supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the ADSL Router queries all directly connected networks
to gather group membership. After that, the ADSL Router periodically updates this
information. IP multicasting can be enabled/disabled on the ADSL Router LAN
and/or WAN interfaces in the web configurator (LAN; WAN). Select None to
disable IP multicasting on these interfaces.

CHAPTER 6: WAN Setup
This chapter describes how to configure WAN settings.
6.1 WAN Overview
A WAN (Wide Area Network) is an outside connection to another network or the
Internet.
See the Wizard Setup chapter for more information on the fields in the WAN
screens.
6.2 PPPoE Encapsulation
The ADSL Router supports PPPoE (Point-to-Point Protocol over Ethernet).
PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal
computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.)
connection. The PPPoE 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). PPPoE
provides a login and authentication method that the existing Microsoft Dial-Up
Networking software can activate, and therefore requires no new learning or
procedures for Windows users.
One of the benefits of PPPoE is the ability to let you access one of multiple
network services, a function known as dynamic service selection. This enables
the service provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier,
as it requires no specific configuration of the broadband modem at the customer
site.
By implementing PPPoE directly on the ADSL Router (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the ADSL Router does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
6.3 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables
secure transfer of data from a remote client to a private server, creating a Virtual
Private Network (VPN) using TCP/IP-based networks.
PPTP supports on-demand, multi-protocol and virtual private networking over
public networks, such as the Internet.
6.4 Traffic Shaping
Traffic Shaping is an agreement between the carrier and the subscriber to
regulate the average rate and “burstiness” or fluctuation of data transmission over
A02-RA111 / A02-RA141 Pag. 36
WebShare 111/141
an ATM network. This agreement helps eliminate congestion, which is important
for transmission of real time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells.
This parameter may be lower (but not higher) than the maximum line speed. 1
ATM cell is 53 bytes (424 bits), so a maximum speed of 832 Kbps gives a
maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is
dependent on the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source
that can be sent at the peak rate, and a parameter for burst-type traffic. SCR may
not be greater than the PCR; the system default is 0 cells/sec.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at
the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages
to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR
again.The following figure illustrates the relationship between PCR, SCR and
MBS.

CHAPTER 7: Network Address Translation
(NAT)
This chapter discusses how to configure NAT on the WebShare Router ADSL2+.
7.1 NAT Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP
address of a host in a packet, for example, the source address of an outgoing
packet, used within one network to a different IP address known within another
network.
7.1.1 NAT Definitions
Inside/outside denotes where a host is located relative to the ADSL Router, for
example, the computers of your subscribers are the inside hosts, while the web
servers on the Internet are the outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses
a router, for example, the local address refers to the IP address of a host when
the packet is in the local network, while the global address refers to the IP
address of the host when the same packet is traveling in the WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to
the IP address of a host used in a packet. Thus, an inside local address (ILA) is
the IP address of an inside host in a packet when the packet is still in the local
network, while an inside global address (IGA) is the IP address of the same inside
host when the packet is on the WAN side. The following table summarizes this
information.
Item Description
Inside This refers to the host on the LAN.
Outside This refers to the host on the WAN.
Local This refers to the packet address (source or destination) as the packet
travels on the LAN.
Global This refers to the packet address (source or destination) as the packet
travels on the WAN.
7.1.2 What NAT Does
In the simplest form, NAT changes the source IP address in a packet received
from a subscriber (the inside local address) to another (the inside global address)
before forwarding the packet to the WAN side. When the response comes back,
A02-RA111 / A02-RA141 Pag. 43
WebShare 111/141
NAT translates the destination address (the inside global address) back to the
inside local address before forwarding it to the original inside host. Note that the
IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically
assigned by the ISP. In addition, you can designate servers, for example, a web
server and a telnet server, on your local network and make them accessible to the
outside world. With no servers defined, the ADSL Router filters out all incoming
inquiries, thus preventing intruders from probing your network. For more
information on IP address translation, refer to RFC 1631, The IP Network Address
Translator (NAT).
7.1.3 How NAT Works
Each packet has two addresses – a source address and a destination address.
For outgoing packets, the ILA (Inside Local Address) is the source address on the
LAN, and the IGA (Inside Global Address) is the source address on the WAN. For
incoming packets, the ILA is the destination address on the LAN, and the IGA is
the destination address on the WAN. NAT maps private (local) IP addresses to
globally unique ones required for communication with hosts on other networks. It
replaces the original IP source address (and TCP or UDP source port numbers for
Many-to-One and Many-to-Many Overload NAT mapping) in each packet and
then forwards it to the Internet. The ADSL Router keeps track of the original
addresses and port numbers so incoming reply packets can have their original
values restored. The following figure illustrates this.
7.1.4 NAT Application
The following figure illustrates a possible NAT application, where three inside
LANs (logical LANs using IP Alias) behind the ADSL Router can communicate

with three distinct WAN networks. More examples follow at the end of this
chapter.
7.1.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
1. One to One: In One-to-One mode, the ADSL Router maps one local IP
address to one global IP address.
2. Many to One: In Many-to-One mode, the ADSL Router maps multiple local IP
addresses to one global IP address.
3. Many to Many Overload: In Many-to-Many Overload mode, the ADSL Router
maps the multiple local IP addresses to shared global IP addresses.
4. Many-to-Many No Overload: In Many-to-Many No Overload mode, the ADSL
Router maps each local IP address to a unique global IP address.
5. Server: This type allows you to specify inside servers of different services
behind the NAT to be accessible to the outside world.
The following table summarizes these types.

7.2 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a implementation of a subset of NAT that supports
two types of mapping, Many-to-One and Server. The ADSL Router also supports
Full Feature NAT to map multiple global IP addresses to multiple private LAN IP
addresses of clients or servers using mapping types as outlined in
7.3 Virtual Server and DMZ
A Virtual server set is a list of inside (behind NAT on the LAN) servers, for
example, web or FTP, that you can make visible to the outside world even though
SUA makes your whole inside network appear as a single computer to the outside
world.
You may enter a single port number or a range of port numbers to be forwarded,
and the local IP address of the desired server. The port number identifies a
service; for example, web service is on port 80 and FTP on port 21. In some
cases, such as for unknown services or where one server can support more than
one service (for example both FTP and web service), it might be better to specify
a range of port numbers. You can allocate a server IP address that corresponds to
a port or a range of ports.
Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
Default Server IP Address
In addition to the servers for specified services, NAT supports a default server IP
address. A default server receives packets from ports that are not specified in this
screen.
7.3.1 Port Forwarding: Services and Port Numbers
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example,
web or FTP, that you can make accessible to the outside world even though NAT
makes your whole inside network appear as a single machine to the outside
world.
Use the SUA Server page to forward incoming service requests to the server(s)
A02-RA111 / A02-RA141 Pag. 46
WebShare 111/141
on your local network. You may enter a single port number or a range of port
numbers to be forwarded, and the local IP address of the desired server. The port
number identifies a service; for example, web service is on port 80 and FTP on
port 21. In some cases, such as for unknown services or where one server can
support more than one service (for example both FTP and web service), it might
be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A
service request that does not have a server explicitly designated for it is
forwarded to the default server. If the default is not defined, the service request is
simply discarded.
The most often used port numbers are shown in the following table. Please refer

Ordering your rules is important because the ADSL Router applies the rules in the
order that you specify. When a rule matches the current packet, the ADSL Router
takes the corresponding action and the remaining rules are ignored. If there are
any empty rules before your new configured rule, your configured rule will be
pushed up by that number of empty rules. For example, if you have already
configured rules 1 to 6 in your current set and now you configure rule number 9.
In the set summary screen, the new rule will be rule 7, not 9. Now if you delete
rule 4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become
new rules 4, 5 and 6.

8.4 UPnP
UPnP offers peer-to-peer network connectivity for PCs and other network
devices, along with control and data transfer between devices. UPnP offers many
advantages for users running NAT routers through UPnP NAT Traversal, and on
supported systems makes tasks such as port forwarding much easier by letting
the application control the required settings, removing the need for the user to
control advanced configuration of their device.
Both the user’s Operating System and the relevant application must support
UPnP in addition to the router. Windows XP and Windows Me natively support
UPnP (when the component is installed), and Windows 98 users may install the
Internet Connection Sharing client from Windows XP in order to support UPnP.
Windows 2000 does not support UPnP.

Select this check box to allow UPnP-enabled
applications to automatically configure the
WEBSHARE ROUTER ADSL2+ so that they can
communicate through the WEBSHARE ROUTER
ADSL2+, 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
The Dynamic DNS function allows you to alias a dynamic IP address to a static
hostname, allowing users whose ISP does not assign them a static IP address to
use a domain name. This is especially useful for hosting servers via your ADSL
connection, so that anyone wishing to connect to you may use your domain
name, rather than having to use your dynamic IP address, which changes from
time to time. This dynamic IP address is the WAN IP address of the router, which
is assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS
provider using their website, for example http://www.dyndns.org/

9.2 NAT
The NAT (Network Address Translation - NAT, RFC 1631) is the translation of the
IP address of a host in a packet. The default setting is Dynamic NAPT. It
provides dynamic Network Address Translation capability between LAN and
multiple WAN connections, and the LAN traffic is routed to appropriate WAN
connections based on the destination IP addresses and Route Table. This
eliminates the need for the static NAT session configuration between multiple
LAN clients and multiple WAN connections.

The DMZ Host is a local computer exposed to the Internet. When setting a
particular internal IP address as the DMZ Host, all incoming packets will be

entries.

Select the Apply button to apply your changes.
9.2.3 Virtual Server
In TCP/IP and UDP networks a port is a 16-bit number used to identify which
application program (usually a server) incoming connections should be delivered
to. Some ports have numbers that are pre-assigned to them by the IANA (the
Internet Assigned Numbers Authority), and these are referred to as “well-known
ports”. Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the
WAN (i.e. from other machines on the Internet that are outside your local
network), or any application that can accept incoming connections (e.g.
Peer-to-peer/P2P software such as instant messaging applications and P2P
file-sharing applications) and are using NAT (Network Address Translation),
then you will usually need to configure your router to forward these
incoming connection attempts using specific ports to the PC on your
network running the application. You will also need to use port forwarding if
you want to host an online game server
The reason for this is that when using NAT, your publicly accessible IP address
will be used by and point to your router, which then needs to deliver all traffic to
the private IP addresses used by your PCs. Please see the WAN configuration
section of this manual for more information on NAT.
The device can be configured as a virtual server so that remote users accessing
services such as Web or FTP services via the public (WAN) IP address can be
automatically redirected to local servers in the LAN network. Depending on the
requested service (TCP/UDP port number), the device redirects the external
service request to the appropriate server within the LAN network.

If you have disabled the NAT option in the WAN-ISP section, the Virtual
Server function will hence be invalid.
If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid
conflicts. The easiest way of configuring Virtual Servers is to manually
assign static IP address to each virtual server PC, with an address that
does not fall into the range of IP addresses that are to be issued by the
DHCP server. You can configure the virtual server IP address manually,
but it must still be in the same subnet as the router.

Your router’s “firmware” is the software that allows it to operate and provides all
its functionality. Think of your router as a dedicated computer, and the firmware
as the software it runs. Over time this software may be improved and modified,
and your router allows you to upgrade the software it runs to take advantage of
these changes.
To upgrade the firmware of WEBSHARE ROUTER ADSL2+, you should
download or copy the firmware to your local environment first. Press the

Make sure you are using the correct IP address of the ADSL
Router. Check the IP address of the ADSL Router.
Ping the ADSL Router from your computer.
If you cannot ping the ADSL Router, check the IP addresses of
the ADSL Router and your computer. Make sure your computer
is set to get a dynamic IP address; or if you want to use a static
IP address on your computer, make sure that it is on the same
subnet as the ADSL Router.
