The bintec R4100 is a high-performance IP router designed for small and medium-sized enterprises and can be used as a WAN access router or as a central remote access server. The bintec R4100 already comes complete with two BRI interfaces, allowing the use of four ISDN B channels. The two PRI interfaces can also be activated optionally. In addition to the ISDN BRI and PRI interfaces, a DSP slot has also been integrated for up to 32/64 simultaneous VoIP channels, making it possible to use the router as a VoIP media gateway.
Because the bintec R4100 supports a maximum of 68 ISDN-B channels, this device is ideally equipped to serve as a central remote access server in corporate environments. In addition to the connection of local end systems, the integrated 4-port switch can also be used in combination with an external modem for WAN access. The separate DMZ port makes it possible to provide central server services.
The extensive IPSec implementation supports the building of secure VPN infrastructures. The device already comes complete with 10 active IPSec tunnels including hardware acceleration and encryption. 3DES or AES is used for encryption, while preshared keys or certificates can be used for authentication. It is also easy to integrate a Radius server into the system. A flexible licensing model allows the activation of up to 100 additional VPN tunnels.
This router also sports an extensive range of software features. The stateful inspection firewall provides protection against attacks from the outside. Content filtering* allows you to block out any Web contents before they reach the internal network. The integrated PPPoE client/server function makes it possible to define user-specific rules for network use, while QoS mechanisms ensure optimum use of the available bandwidth and provide all the services you require. The devices can be configured using either the HTTP Configuration Wizard (recommended for inexperienced users) or via an HTML user interface. The SSH-encrypted communication to the device provides for secure configuration.
