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.

You have to configure the type of traffic passed between WAN and LAN, please refer to Packet Filter below. High, Medium and Low security level: By default, your system use High, Medium or Low firewall security level between WAN and LAN. For example, when you select High, the Port Filters of Packet Filter screen will be set automatically according to High security level settings.
The Firewall – Packet Filter is shown as below.
You may configure to filter inbound (incoming) and outbound (outgoing) packets based on PORT or IP address.
If it is based on PORT, click Port Filters for more options. You may filter the packets based on PORT and packet type (TCP or UDP or any). For example, the protocol number 1 means ICPM. You may enter 1 to protocol number of Raw IP Filtering web page. The port range is supported.
If it is based on the IP address, click Address Filters for more options. You may enter the IP address and again to select the inbound or outbound packets.

3.4.3.6 Virtual Server
When you click Virtual Server, you get the following figure.
Being a natural Internet firewall, this network router protects your network from being accessed by outside users. When it needs to allow outside users to access internal servers, e.g. Web server, FTP server, E-mail server or News server, this product can act as a virtual server. You can set up a local server with specific port number that stands for the service, e.g. Web (80), FTP (21), Telnet (23), SMTP (25), POP3 (110), When an incoming access request to the router for specified port is received, it will be forwarded to the corresponding internal server.
For example, if you set the Service Port number 80 (Web) to be mapped to the IP Address
192.168.0.2, then all the http requests from outside users will be forwarded to the local server with IP address of 192.168.0.2. If the port is not listed as a predefined application, you need to add it manually.
DMZ: Regarding the DMZ Host, it is a local computer exposed to the Internet. Therefore, an incoming packet will be checked by the Firewall and NAT algorithms, then passed to the DMZ host when a packet is not sent by a hacker and not limited by the virtual server list.
If you have disabled the NAT option in the WAN-ISP section, this 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 easy way is that the IP address assigned to each virtual server should not fall into the range of IP addresses that are to be issued by the DHCP server. You configure the virtual server IP address manually, but it is still in the same subnet with the router.
29
3.4.3.7 Advanced
There are two items under the Advanced section, Static Routing and Dynamic DNS. When you click Static Routing and then click Create IP V4Route to get the below figure to add a routing table.
Destination: Enter the destination subnet IP.
Chapter 3 Configuration
Gateway: Enter the gateway IP address which the packet is forwarded to. Netmask: Subnet mask of destination IP addresses based on above destination subnet IP. Cost: This is the same meaning as Hop. Usually, leave it as 1. Interface : Enter the interface which the packet is forwarded to.
Click Dynamic DNS to get the below figure then check the “Enable” button to access the Dynamic DNS service.
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.
Dynamic DNS: Select the registered DDNS server. Domain Name, Username and Password: Enter the registered domain name, username and
password.

None of the LEDs are on when you turn on the TW-EA1000.
Check the connection between the adapter and the TW­EA1000. If the error persists, you may have a hardware problem. In this case you should contact technical support.
Problems with the WAN Interface
Problem Corrective Action
Initialization of the PVC connection failed.
Ensure that the cable is connected properly from the ADSL port to the wall jack. The ADSL LED on the front panel of the TW-EA1000 should be on. Check that your VPI, VCI, type of encapsulation and type of multiplexing settings are the same as what you collected from your telephone company and ISP. Reboot the TW-EA1000. If you still have problems, you may need to verify these variables with the telephone company and/or ISP.
Problems with the LAN Interface
Problem Corrective Action
32
Can’t ping any station on the LAN.
Check the Ethernet LEDs on the front panel. The LED should be on for a port that has a station connected. If it is off, check the cables between your TW-EA1000 and the station. Make sure you have uninstalled any software firewall. Verify that the IP address and the subnet mask are consistent between the TW-EA1000 and the workstations.
