Applications

The SpeedStream 2614 by Siemens provides many advanced features and functionality:

•LAN Access – The SpeedStream 2614 provides connectivity to 10/100 Mbps devices, making it easy to create a network in small offices or homes.

•Internet Access – This device supports Internet access through an xDSL, cable, ISDN or PSTN connection. Since many DSL providers use PPPoE to establish communications with end users, the SpeedStream 2614 includes a built-in PPPoE client, eliminating the need to install this service on your computer.

•Shared IP Address – The SpeedStream 2614 provides Internet access for up to 253 users with a single shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time.

•Virtual Server – If you have a fixed IP address, you can set up the SpeedStream 2614 to act as a virtual host for network address translation. Remote users access various services at your site via a constant IP address. Then, depending on the requested service (or port number), the SpeedStream 2614 can route the request to the appropriate server at another internal IP address. This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network.

•User-DefinableApplication-Sensing Tunnel – You can define special applications that require multiple connections such as Internet gaming, video conferencing, and Internet telephony. The SpeedStream 2614 will then sense the application type and open a multi-port tunnel for it.

•DMZ Host Support – The SpeedStream 2614 allows a networked computer to be fully exposed to the Internet. This function is used when the special application-sensing tunnel feature is insufficient to allow an application to function correctly.

•Security – The SpeedStream 2614 supports security features that can deny Internet access to specified users, or filter all requests for specific services the administrator does not want to serve. The SpeedStream 2614’s firewall can also block common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

•Virtual Private Network – The SpeedStream 2614 supports three of the most commonly used VPN protocols: PPTP, L2TP and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, any of these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet. The VPN protocols supported by the SpeedStream 2614 are briefly described below:

-Point-to-Point Tunneling Protocol provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs.

-Layer Two Tunneling Protocol includes most of the features provided by PPTP, but has less overhead and is more suited for managed networks.

-IP Security provides IP network-layer encryption and can support large encryption networks, such as the Internet, by using digital certificates for device authentication.
