ADSL router with SIP proxy and IPSec

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. 

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 IPSec implementation and are already equipped with two active VPN tunnels straight from the factory.
