Introduction
1.1 An Overview of the TW-EA1000
TW-EA1000 Wireless ADSL Firewall Router provides office and residential users the ideal
solution for sharing a high-speed ADSL broadband Internet connection among an 11Mbps
wireless network and a 10/100Mbps Fast Ethernet backbone. It can support 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).
The product 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 ISP. Besides, an embedded PPTP client and PPTP
server are supported to establish a VPN tunnel with a remote PPTP device. 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 provides the natural firewall function (Network Address Translation,
NAT), it also provides rich firewall features to secure a 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 three 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, a user can open some specific ports for outside users to access
internal services in the network. Finally it can also detect and block many Hacker Patterns and
not allow hackers into your network.
Integrated DHCP services, client and server, allows up to 253 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 a 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 Server function allows the product to provide limited visibility to
local machines with specific services for outside users. An ISP 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
1
TW-EA1000 Wireless ADSL Firewall Router
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.

Chapter 1 Introduction
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
http://www.dyndns.org/. 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 di stri bute 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.

3.1 Before Configuration
This section describes the configuration required by LAN-attached PCs that communicate with
the TW-EA1000, either to configure the device, or for network access. These PCs must have an
Ethernet interface installed properly, be connected to the TW-EA1000 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 of the TWEA1000. The default IP address of the TW-EA1000 is 192.168.0.254 and subnet mask is
255.255.255.0. The best and easy way is to configure the PC to get an IP address from the TWEA1000 Router. Also make sure you have UNINSTALLED any kind of software firewall that
can cause problems accessing the 192.168.0.254 IP address of the router.
Please follow the steps below for PC’s network environment installation. First of all, please
check your PC’s network components. The TCP/IP protocol stack and Ethernet network adapter
