Introduction
1.1 An Overview of the WebShare 241
Broadband Sharing and IP sharing
The WebShare 241 supports 4 x 10/100 Mbps auto-negotiating Fast Ethernet ports for
connection to your PC or LAN and downstream (with built-in ADSL2+ modem) rate up to
24Mbps. Power by NAT technology, dozens of network users can surf on the Internet and
share the ADSL connection simultaneously by using one ISP account and one single IP
address.
Security: Firewall & VLAN
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.
The VLANs allow to segment the traffic of net and, in this way, they improve management
and performance of entire network.
Quality of Service and IP Throttling
QoS gives you full control over which types of outgoing data traffic should be given priority by
the router, ensuring important data like gaming packets move through the router at lightning
speed, even under heavy load.
Using IP Throttling, bandwidth limits can be enforced on any system within your LAN, or even
on a particular application.
Easy Configuration and Management
Support web based GUI and Telnet for configuration and management. Also supports remote
management (Web and telnet) capability for remote user to configure and manage this
product. It incorporates besides a client Dynamic DNS.

1.3 WebShare 241 Features
ADSL Router2+ provides the following features:
•ADSL Multi-Mode Standard: Supports downstream transmission rates of up to
8Mbps, the router is capable of up to 12/24 Mbps with ADSL2/2+, and upstream
transmission rates of up to 1024Kbps. It also supports rate management that allows
ADSL subscribers to select an Internet access speed suiting their needs and budgets.
It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1);
G.lite (G992.2); G.hs(G994.1); G.dmt.bis(ITU G.992.3); Gdmt.bisplus(ITU G.992.5)].
•Fast Ethernet Switch: A 4-port 10/100Mbps fast Ethernet switch is supported in the
LAN site and automatic switching between MDI and MDI-X for 10Base-T and
100Base-TX ports is supported. An Ethernet straight or cross-over cable can be used
directly, this fast Ethernet switch will detect it automatically.
•Multi-Protocol to Establish A Connection: Supports PPPoA (RFC 2364 - PPP 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
the ISP. The product also supports VC-based and LLC-based multiplexing.
•Quick Installation Wizard: Supports a WEB GUI page to install this device quickly.
With this wizard, an end user can enter the information easily which they from the ISP,
then surf the Internet immediately.
•Universal Plug and Play (UPnP) and UPnP NAT Traversal: This protocol is used to
enable simple and robust connectivity among stand-alone devices and PCs from
many different vendors. It makes network simple and affordable for users. UPnP
architecture leverages TCP/IP and the Web to enable seamless proximity networking
in addition to control and data transfer among networked devices.
•Network Address Translation (NAT): Allows multi-users to access outside resource
such as Internet simultaneously with one IP address/one Internet access account.
Besides, many application layer gateway (ALG) are supported such as web browser,
ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting and others.
•Firewall: Supports SOHO firewall with NAT technology. Automatically detects and
blocks the Denial of Service (DoS) attack. The URL-blocking, packet filtering are also
supported. The hacker’s attack will be recorded associated with timestamp in the
security logging area. More firewall features will be added continually, please visit our
web site to download latest firmware.
•VLAN: A VLAN is a group of end-stations that are not constrained by their physical
location and can communicate as if a common broadcast domain, a LAN. The primary
utility of using VLAN is to reduce latency and need for routers, using faster switching
instead. Other VLAN utility includes:

WEBSHARE 241

•Security, Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched to
only those confidential users within the VLAN.
•Cost Reduction, VLANs can be used to create multiple broadcast domains,
thus eliminating the need of expensive routers.
•Port-based (or port-group) VLAN is the common method of implementing a
VLAN, and is the one supplied in the Switch.
•QoS: QoS gives you full control over which types of outgoing data traffic should be
given priority by the Router, ensuring important data like gaming packets move
through the Router at lightning speed, even under heavy load. The QoS features are
configurable by source IP address, destination IP address, protocol, and port. You can
throttle the speed at which different types of outgoing data pass through the router, to
ensure P2P users don’t saturate upload bandwidth, or office browsing doesn’t bring
client web serving to a halt. In addition, or alternatively, you can simply change the
priority of different types of upload data and let the router sort out the actual speeds.
•Domain Name System (DNS) relay: provides an easy way to map the domain name
(a friendly name for users such as www.yahoo.com) and IP address. When a local
machine sets its DNS server with this router’s IP address, then every DNS conversion
requests packet from the PC to this router will be forwarded to the real DNS in the
outside network. After the router gets the reply, then forwards it back to the PC.
•Dynamic Domain Name System (DDNS): The Dynamic DNS service allows you to
alias a dynamic IP address to a static hostname. This dynamic IP address is the WAN
IP address. For example, to use the service, you must first apply an account from this
free Web server http://www.dyndns.org/. There are more than 5 DDNS servers
supported.
•PPP over Ethernet (PPPoE): Provide embedded PPPoE client function to establish a
connection. Users can get greater access speed without changing the operation
concept, sharing the same ISP account and paying for one access account. No
PPPoE client software is required for the local computer. The Always ON, Dial On
Demand and auto disconnection (Idle Timer) functions are provided too.
•Virtual Server: Users can specify some services to be visible from outside users. The
router can detect incoming service request and forward it to the specific local
computer to handle it. For example, users can assign a PC in a LAN acting as a WEB
server inside and expose it to the outside network. Outside users can browse an
inside web server directly while it is protected by NAT. A DMZ host setting is also
provided to a local computer exposed to the outside network, Internet
•Rich Packet Filtering: Not only filters the packet based on IP address, but also based
on Port numbers. It also provides a higher-level security control.
•Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the
DHCP client can get an IP address from the Internet Server Provider (ISP)
automatically. In the LAN site, the DHCP server can allocate up to 253 client IP
addresses and distribute them including IP address, subnet mask as well as DNS IP
address to local computers. It provides an easy way to manage the local IP network.

•Static and RIP1/2 Routing: Supports an easy static table or RIP1/2 routing protocol
to support routing capability.
•SNTP: An easy way to get the network real time information from an SNTP server.
•SNMP: SNMP is an application layer protocol that is used for managing networks
(V1,V2 and V3)
•Web based GUI: supports web based GUI for configuration and management. It is
user-friendly with an on-line help, providing necessary information and assist user
timing. It also supports remote management capability for remote users to configure
and manage this product.
•Firmware Upgradeable: the device can be upgraded to the latest firmware through
the WEB based GUI.
•Rich management interfaces: Supports flexible management interfaces with local
console port, LAN port, and WAN port. Users can use terminal application through
console port to configure and manage the device, or Telnet, WEB GUI, and SNMP
through LAN or WAN ports to configure and manage a device.
