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 Multi-player game servers to share the same
Internet-visible IP address while still protecting the servers and LAN users from hackers.

1.3 TW-EA1000 Features
TW-EA1000 provides the following features:
ADSL Multi-Mode Standard:
Supports downstream transmission rates of up to 8Mbps 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).
Wireless Ethernet 802.11b access point:
Provides a wireless Ethernet 802.11b access point for
extending the communication media to WLAN.
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 crossover 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 packet filtering and SPI 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.
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
. There are more than 5 DDNS servers supported.
Virtual Private Network (VPN):
Allows a user to make a tunnel with a remote site directly to
secure the data transmission among the connection. Users can use
embedded PPTP
client/server
supported by this router to make a VPN tunnel or the user can run the PPTP client
in PC and the router already provides IPSec and PPTP pass through function to establish a VPN
connection if the user likes to run the PPTP client in his local computer.
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 will increase the performance in LAN and WAN, also provide 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.
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.
