The bintec RS232b is a powerful and, thanks to its comprehensive
equipment, flexible router. The integrated ADSL 2+ modem on the
RS232b supports Annex B (ADSL over ISDN), which is predominantly
used in Germany, in accordance with ITU G992.1 and is compatible
with Deutsche Telekom's U-R2 connection.
The gateway in the fan-free metal housing guarantees long-term
reliability in critical corporate applications and is ideal for use
as an access router in SMEs, branch offices and home offices. In
addition to the integrated ADSL 2+ modem, the device has five
Gigabit Ethernet ports, which can be configured for LAN, WAN or
DMZ, and comes with a licence for five hardware-accelerated IPSec
tunnels. The built-in ISDN BRI interface and the UMTS USB modem
connected to the USB port can be used as a remote configuration
access and as an ISDN backup interface.
Using functions flexibly
Only a few functions are required to forward data packets between
two networks. The bintec RS232b has features that go far beyond
just routing and allow it to be integrated into complex IT
infrastructures. By using Extended Routing and NAT (ERN) the data
can be routed in IP routing according to criteria such as IP
protocols (Layer 4), source or destination IP address, source or
destination port, TOS/DSCP, source or destination interface and the
status of the destination interface. In addition, you can also use
network address translation to translate the data traffic for both
inbound and outbound connections and individually for each
interface based on a wide range of criteria.
The comprehensive multicast support makes the device ideal for use
in multimedia and streaming applications.
The Stateful Inspection Firewall (SIF) offers effective protection
against attacks from the Internet through dynamic packet filtering.
Firewall handling is made easier through numerous pre-configured
services. An optional content filter rounds off the security
functions of the devices*. In this case, all the outgoing Internet
enquiries are classified and allow contents not wanted to be
reliably filtered out.
The basic equipment of the RS Series also offers a SIP application
level gateway (ALG) for the direct connection of IP telephones in
the network or for registering with a VoIP provider, without
affecting the security of the WAN connection. The corresponding
releases in NAT and the internal Stateful Inspection Firewall are
controlled automatically by ALG for the length of the
Quality of Service is more than a watchword in FEC devices. Thanks
to the rising convergence between voice and data, the
classification of data streams is gaining in importance. Our
gateways provide corresponding QoS mechanisms for prioritising the
VoIP traffic ahead of normal internet traffic, for example, and to
guarantee it sufficient bandwidth. Alternatively you can give
normal data traffic priority over e-mail traffic. The bintec QoS
implementation allows voice data to be processed before e-mal data,
for example, within a VPN tunnel.
The DNS proxy function supports the LAN for address implementation
and the automated IP configuration of PCs is carried out over an
integrated DHCP server.
Remote CAPI is available for the joint use of various ISDN
Comprehensive IPSec implementation
The IPSec implementation integrated in bintec RS232b works not only
with preshared keys but also with certificates. This allows a
public key infrastructure to be created for maximum security. (The
German Federal Office for Information Security also recommends the
use of certificates.)
Furthermore, the bintec IPSec implementation offers support when
creating VPN connections with dynamic IP addresses: Even small
branch offices can be reached without having to be permanently
online. If both VPN nodes only have dynamic IP addresses,
confidential information can continue. The exchange of IP addresses
is carried out either over dynamic DNS providers or directly over
ISDN. The actual dynamic IP address is transferred either in the
ISDN D-channel (free of charge) or, if this is not possible, in the
ISDN B-channel (at cost).
The devices offer a unique level of flexibility thanks to the wide
variety of interfaces supported. The bintec RS232b supports the
ability to configure two interfaces as WAN interfaces. As a result,
there is not only more bandwidth available, but there is the
opportunity to spread data traffic across individual WAN
connections according to load or data type. Equally, you can use a
connection (e.g. SDSL) for the VPN connection to the head office
and use a second WAN port for a low-cost ADSL connection to
guarantee the company's other data traffic. If either connection
fails, the other can take over the entire data transfer. In the
event that both lines fail, data traffic can automatically be
routed over a UMTS modem connected to the USB port.
Simple configuration and maintenance
The router is configured over the Funkwerk Configuration Interface
(FCI), using the integrated configuration wizards for example. The
FCI is a web-based graphic user surface that you can use from any
PC with an up-to-date Web browser via an HTTP or encrypted HTTPS
connection. It also offers the opportunity to manage the devices
locally and remotely over other configuration accesses such as
Telnet, SSH, ISDN Login and GSM dialin (only possible if USB UMTS
modem is connected).
DIME Manager from Funkwerk Enterprise Communications (FEC) is a
free tool for managing FEC devices.
Dime Manager is aimed at administrators who manage networks with up
to 50 devices. The software simplifies the management and
configuration of gateways or access points either individually or
in logical groups.
When developing DIME Manager, simple and efficient operation was
the primary aim. It allows, for example, software updates or
configurations to be applied to individual devices or groups of
devices simply by drag and drop. DIME Manager recognises and
manages new devices in the network using SNMP multicasts, in other
words independent of their current IP address.
