The bintec R3502 is a powerful and, thanks to its comprehensive equipment, flexible VPN gateway. The integrated VDSL2 modem on the R3502 supports the asymmetric band plan 998, which is used in Germany and the majority of European countries, including the corresponding profiles 8b and 17a. The modem also supports automatic switching to ADSL2+. This increases your investment security, as you initially operate the device on an ADSL connection and can then subsequently switch to a VDSL connection depending on availability.
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 R3502 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 built-in ISDN BRI interface can be used as a remote configuration access and as an ISDN backup interface.

The IPSec implementation integrated in bintec R3502 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 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.

In addition to the integrated VDSL modem, bintec R3502 offers the option to use two or even three Ethernet interfaces as additional WAN interfaces with external DSL modems or cable modems. 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 an additional WAN connection (e.g. SDSL) for the VPN connection of branch offices and use the integrated VDSL2 modem to guarantee the company's other data traffic.
Our bintec router redundancy protocol (BRRP) allows two devices to be operated so that they act as a single device in the LAN. Both devices have their own IP and MAC addresses for each interface as well as a joint virtual IP and MAC address. This is registered as the standard gateway for all computers in the LAN. Both of the switched gateways communicate over the bintec protocol and if either device fails, the other device automatically takes over the entire data traffic.

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.

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 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.
