Funkwerk bintec R4402 gateways/controller

bintec R4402, 1U, VPN Gateway, ISDN 2 x BRI/2 x PRI, 10 IPSec, 5 x Gigabit Ethernet, 24W, 2600g, Red bintec R4402
The bintec R4402 is a powerful and, thanks to its comprehensive equipment, flexible VPN gateway. With its 19-inch metal housing and highly efficient internal switched-mode power supply the gateway guarantees long-term reliability in critical corporate applications. This makes the R4402 ideal for use as a VPN gateway in SMEs and company head offices. The device has five Gigabit Ethernet ports, which can be configured for LAN, WAN or DMZ, and comes with a licence for ten hardware-accelerated IPSec tunnels. Up to 100 additional IPSec tunnels can also be enabled if licensed.

The device comes with two ISDN BRI-S0 and two ISDN PRI-S2M interfaces. In total is provides 68 ISDN-B channels for different ISDN applications such as ISDN backup, ISDN remote access server or ISDN leased lines.

Using functions flexibly
Only a few functions are required to forward data between two networks. Bintec gateways have features that go far beyond just routing and allow it to be seamlessly integrated into complex IT infrastructures.

As routing protocols, you can use RIP, OSPF or the Multicast routing protocol PIM-SM for example, and the comprehensive multicast support makes the device ideal for use in multimedia and streaming applications.

Even the basic equipment of the bintec R4402 provides a SIP application level gateway (ALG) for the direct connection of IP telephones in the network or for registering with a VoIP provider. The ALG automatically controls the internal firewall making it easier to configure your VoIP solution.
Thanks to the integrated quality of service, you can prioritise VoIP traffic over normal internet traffic, for example, and thereby always ensure sufficient bandwidth for your IP voice connections. Alternatively you can give normal data traffic priority over e-mail traffic.

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 services.

Comprehensive IPSec implementation
The IPSec implementation integrated in bintec R4402 works not only with preshared keys but also with certificates. This allows a public key infrastructure to be created for maximum security. (The 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 an ISDN connection. The actual dynamic IP address is transferred either free of charge in the ISDN D-channel or, if this is not possible, in the B-channel (at cost).

By using IKE Config mode and the bintec IPSec multi user this offers the opportunity to create and manage IPSec dial-in solutions for multiple clients with minimal expense and IKE X-Auth (extended authentication) allows a connection to be secured with a one time password and thus with the highest level of security.

Simple configuration and maintenance
The gateway 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 and ISDN login.
