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-Definable Application-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.
