The SpeedTouch 500Series at a Glance
Combining today's DSL technology with unique features as an integrated and programmable Firewall, advanced IP Router functionality and LAN services, yet easy configurable for all most common Internet connection services and featuring full UPnP support, the SpeedTouch 500Series Multi-User DSL Gateway is the ideal solution for demanding Internet users.
Introducing DSL
DSL is short for Digital Subscriber Line. This somewhat cryptic name is best explained in straightforward terms:
* Line
DSL uses the ordinary existing copper line, known as "local loop, running between your local premises and the telephone central office.
* Subscriber
That's you, the end-user. Because this is what Service Providers or operators call their customers.
* Digital
DSL is a digital transmission technology. To a certain extend, digital information is not affected by impairments on the telephone line, thus achieving a higher reliability.
Compared to traditional analog or ISDN modems, DSL transfers information up to 200 times faster and even more depending on the applied DSL service, local loop length and loop quality.
The popular term DSL refers to lot more than the raw "DSL Technology? alone. Indeed, on one hand DSL refers to advanced modulation and demodulation techniques, applied to the copper wire between a subscribers? home and the telephone service provider?s central office. The net result of this technology is a boost in bandwidth from a few tens of kilobits to a multiple of megabits.
On the other hand, as the distance DSL covers is limited to only a few kilometers, a wide area communication infrastructure is required to transport data to ISPs and Corporate data centers. For this purpose, Asynchronous Transfer Mode (ATM) has been selected.
ATM is a connection-oriented packet switching technology using fixed-size packets, called cells. These cells consist of a header and a payload and are switched through a private or public ATM network, depending on the contents of the header. End-to-end connections are formed by cross-connecting individual ATM segments in ATM switches.
Connection and Packet Services
As part of the DSL service provisioning the ISP configures a Connection Service at the remote end of each virtual channel.
Connectivity to the Internet or an Enterprises? Intranet is by far the most important service offered by an ISP. To provide this end-to-end service your ISP will require the SpeedTouch 500Series to use of a certain frame format on the virtual channel running between the SpeedTouch 500Series and its access server. As a consequence, the SpeedTouch 500Series must be configured to correctly adhere to the Central Office settings and requirements.
All these requirements can be collectively referred to as Connection Service and consist of a connection service name, the virtual channel identifier, the connection service type, and the ATM encapsulation type. Whether a connection is always-on or dial-up and the way IP configuration is accomplished in the remote end, is mostly implied in the connection service name. E.g. PPP is native dial-up and IP configuration happens via PPP-IPCP.
The SpeedTouch 500Series supports all common Connection Services to be configured:
* Ethernet over ATM (ETHoA) - RFC1483/Bridged
* PPP over ATM (PPPoA) - RFC2364
* IP over ATM (IPoA) - RFC1483/Routed
Another important aspect refers to the way it should forwards frames or packets between the DSL line and LAN ports and vice versa. To accomplish this, the Connection Service offered on the DSL line needs to be ?attached? to the appropriate Packet Service in the SpeedTouch 500Series.
A Packet Service be defined as: the actions that need to be performed on each data packet in order to filter or forward packets to the next device in the communication chain.
Otherwise stated, a Packet Service is a combination of processes transferring data packets from one side of the SpeedTouch 500Series to the other side and vice versa. E.g. it will forward data packets from your PCs to remote destinations and vice versa. Yet all packet services will prevent communication between devices on your local network from escaping via the DSL line.
Different Packet Services will be called upon depending on:
* The port on which packets arrive e.g. LAN port or DSL port;
* The type of data packets, i.e. whether it concerns IP packets, MAC frames or PPP frames;
* Their properties e.g. unicast, multicast;
* The actual configuration of your SpeedTouch 500Series.
Your SpeedTouch 500Series supports the following Packet Services:
* Bridged Ethernet
* Routed Ethernet
* Bridged PPPoE
* Routed PPPoE
* PPPoE Relay
* Relayed PPPoA
* Routed PPPoA
* Routed IPoA
* Classical IP.
One or more of these Packet Services can be automatically configured at time of installation via the (embedded) Setup wizard, or via uploading the appropriate configuration file or configuration template.
IP Router and LAN Services
The SpeedTouch 500Series offers a broad range of IP functionality, going from (labeled) IP routing, logical multi-homing, Classless InterDomain Routing (CIDR) and Variable Length Subnet Masking (VLSM) over the built-in DHCP Server, DHCP Relay, DHCP Client and DNS Server and Proxy, up to support for advanced Network Address and Port Translation (NAPT) techniques and UPnP NAPT Traversal functionality, and an integrated Packet Firewall.
Universal Plug and Play (UPnP)
The SpeedTouch 500Series provides full support for UPnP and the UPnP Internet Gateway Device (IGD) standard. UPnP allows to easily access and control your SpeedTouch 500Series via an icon on your PC. UPnP and its NAPT Traversal feature provides broadband users at home with a seamless way to participate in online games, videoconferencing and other peer-to-peer services.
UPnP is supported on Windows XP natively. For Windows 98/ME and Windows 2000 UPnP is not supported. However installing DirectX8.1, or DirectX9.0 and later will enable games to use the UPnP NAPT Traversal feature.
For more information on how you can use the SpeedTouch 500Series' UPnP functionality, you can check the SpeedTouch support pages at http://www.speedtouch.com/upnp.htm.

IP Addresses
The IP address table shows all IP addresses configured on any interface of the SpeedTouch 500Series. Some of the IP addresses are configured automatically at boot time, others are either manually configured or negotiated on the fly.
For each IP address, the following information is provided:
* The interface for which the IP address applies
* The IP address and (sub)net mask
* The IP address type
o auto
For IP addresses that are automatically assigned by the SpeedTouch 500Series
o extra
Manually added IP addresses
o user
The default main IP address of the SpeedTouch 500Series' IP host
o CIP
To identify the local IP address of a Classical IP interface
* Whether NAPT is applied on the IP address (pat) or not (none).
Via the IP address table you can also manually add, or delete IP addresses.
IP Routing
The IP Routing table presents the current content of the SpeedTouch 500Series Routing Information Base (FIB). It contains all routes to all possible destinations and is consulted by the SpeedTouch 500Series anytime prior to sending or forwarding any packets.
Similar to the IP address table, a number of IP Routes are pre-configured. Other routes are either added automatically by adding an IP address or via the address negotiation of a Packet Service connection session, or can be added manually.
The SpeedTouch 500Series IP Routing mechanism is based on the labeled routing feature; an extension of the preceding source-routing capability. With label-based routing, packets can be validated against a set of user-defined rules and, if matching, consequently classified by assigning a label, in order to apply specific routing rules to it. This way the SpeedTouch 500Series is capable of forwarding packets matching specific parameters according specific labeled routes. More information on Packet classification can be found in this Help's Packet Classification section (See Advanced Features for more information.
Interface routes are routes assigned to one of the SpeedTouch 500Series interfaces rather than route to a fixed IP address (i.e. the gateway's IP address). This allows configuration of routes for destinations, for which at time of configuration the gateway IP address is not yet known, or the local peer interface is not assigned with an IP address. Interface routes are indicated in the IP Routing table with an asterisk.
Only in special circumstances routes should be manually added/configured or deleted to/in or from the SpeedTouch 500Series' Forwarding Information Base.
Network Address and Port Translation
Network address (and Port) translation (NAPT) is a technique used to share one IP address amongst several computers. For most common applications, enabling NAPT on a specific interface is adequate. From then on, all clients behind the NAPT router automatically share the same IP address. To run a server behind a NAPT router, extra configuration is needed. On the NAPT page, you can specify these settings.
The NAPT web page contains four tabs:
* NAPT Entries
* Multi-NAT Entries
* Default Server
* UPnP
NAPT Entries
For outgoing connections, NAPT entries are created dynamically whenever information migrating through this connection tries to reach a foreign host. For incoming connections however this is not done, mainly for security reasons, so therefore the NAPT entries table allows you to specify static NAPT entries. A static NAPT entry will redirect all incoming connections on a specified address/port to an address/port in the local network.
The SpeedTouch 500Series can have multiple IP addresses, therefore you can specify the IP address in the Outside IP box on which to perform NAPT, and the Outside port. Using 0.0.0.0 as outside IP address causes a template to be created, which will be valid for every one of the SpeedTouch 500Series' NAPT enabled IP addresses established AFTER the creation of the template. In the input boxes 'Inside IP' and 'Inside PORT' you can specify the local machine and port to which traffic needs to be redirected.
The Protocol selection box is used to specify the protocol of the traffic expected to be received on the inside IP:PORT. Keep in mind that the Inside and Outside Ports only need to be specified for the TCP and UDP protocols. All other protocols don't need a port to be specified.
Notice that saving static NAPT entries could be a problem if you work with dynamic IP addresses (for example, if you use a PPP link to connect to the internet, then the SpeedTouch 500Series will get a different IP address every time you establish a connection). In this case the only way to be able to save your settings is to use a template, so that you don't have to specify which SpeedTouch 500Series IP address to use.
