bintec R230a | R230aw
ADSL router with SIP proxy and IPSec
Approval and homologation in Switzerland
The bintec R230a / R230aw are the successor products of X2301 /
X2301w and in addition both models offer the same feature set
available in their predecessors. The bintec R230aw also includes
WLAN function. A memory extension and new features in the
software release for these devices transform them into flexible IP
access routers with an integrated ADSL modem (Annex A) and with
a 4-port switch.
ADSL2+ enables a high-performance WAN connection and allows
download rates of up to 24 Mbps. The WLAN function provides for
exceptional flexibility when using the routers in wireless
environments. An SIP proxy regulates transparent communication to
SIP providers and makes it possible to use the routers in VoIP
scenarios, such as for Internet telephony.
The Application Level Gateway makes it possible for IP telephones to establish a connection to SIP
providers in the LAN, without compromising the security of the WAN connection. Thus, the SIP proxy
monitors the signalization process between the IP phone and the SIP provider and performs all the
necessary NAT and firewall procedures dynamically for the duration of communications. It is also possible
to easily configure and use several different SIP providers on the router.
The R230aw’s wireless interface transmits the data at a maximum rate of 54 Mbps (802.11g) and is
compatible with the 802.11b 11 Mbps version in the same frequency range. Encryption via the WLAN
interface can use WPA and WPA2. Multi-SSID can be used to define virtual WLAN interfaces, making it
possible to establish different access rules for the WLAN, e.g. to log on internal employees and external
visitors. The HTTP Wizard can be of valuable assistance in configuring the WLAN component. 
Both routers come complete with powerful VPN implementation and are already equipped with two VPN
tunnels straight from the factory (with Release 7.6.1 or higher: 5 IPSec tunnels, optional up to 5 PPTP
tunnels). In addition to encryption with AES or 3DES, both routers offer authentication via certificates or
pre-shared keys. To optimize the encrypted data stream, IPComp can be used to compress it. The
dead-peer detection function makes it possible to check the availability of the tunnel end point and
reconnects the tunnel if it is inactive. Along with NAT Traversal, the integration of Radius or Tacacs+ for
authentication purposes is also supported.
In order to be able to find partners despite dynamic IP addresses, the routers support the DynDNS function.
The implementation is compatible with leading European DynDNS suppliers and seven providers are
already pre-installed. The Stateful Inspection Firewall (SIF) offers effective protection against attacks from
the Internet through dynamic packet filtering. Using the firewall is made considerably easier by the wide
range of pre-configured services. The router security functions are rounded out by optional content
filtering*, which classifies all outgoing Internet queries and makes it possible to reliably filter out any
undesirable contents.
Both models can work not only as PPPoE clients but as PPPoE servers as well, which makes it possible to
allocate different privileges to individual users in the network. In combination with the router scheduling
function, specific periods of times can be defined during which users are allocated individual privileges,
