The high-end VPN router - with DSL and 4G modem - is manufactured to the highest quality standards and is ideal for setting up secure branch networks or connecting ATMs thanks to its high level of flexibility.

The NG2000-D 4G has an integrated DSL modem that supports the VDSL2, VDSL2 vectoring, ADSL/2/2+, SuperVectoring and G-fast standards so that the router can be operated on all modern DSL connections. The WAN port allows the realization of any gateway connections as well as the connection of external modems (e.g. SDSL, cable, FTTH).

The integrated 4G radio modem allows the NG2000-D 4G to stay connected via cellular networks, which is particularly useful in environments where DSL connections are unavailable or unstable. This allows the router to maintain a reliable Internet connection anytime, anywhere.

Via a permanently established VPN tunnel, an NG2000-D 4G router can be easily connected to a branch network or to a head office and is thus directly accessible via private IP addressing. DynDNS is not required for access in this case, but can be set up at any time.

The fully implemented VPN standards IPSec and OpenVPN ensure maximum security during data transmission. Authentication is carried out using either stored certificates or pre-shared keys. The VPN router supports all modern encryption algorithms such as AES with a key length of up to 256 bits.

With its modular software structure, the NG2000-D 4G enables the seamless integration of customer-specific software and supports a wide range of network protocols, including IP, TCP, UDP, PPP, ARP, RARP and ICMP. The integrated DHCP (Dynamic Host Configuration Protocol) ensures automatic and efficient network configuration, while the DNS and Dynamic DNS system optimizes domain name management. The router is equipped with the NTP (Network Time Protocol) for precise time synchronization in networks.

In terms of routing, the NG2000-D 4G offers static routing for IPv4 and IPv6 as well as policy-based routing. Network address translation is made possible by NAT (Network Address Translation), while the QoS (Quality of Service) function ensures effective prioritization of data packets. Real-time statistics and a log function are also available.

In terms of security, the NG2000-D 4G offers a zone-based stateful inspection firewall (IPv4/IPv6) with packet filtering and a demilitarized zone (DMZ). It supports a wide range of VPN protocols, including OpenVPN, IPSec, L2TP and WireGuard, enabling secure communication over insecure IP networks. Various hashing and encryption algorithms ensure maximum security.

In the area of high-availability, the NG2000-D 4G offers a MultiWAN manager with complex backup options, including multi-level backup target strategies and optimization of switchover times. VRRP (Virtual Router Redundancy Protocol) with support for Multi group VRRP ensures additional network stability.

Various options are available for efficient management and configuration of the router. Management can be carried out via the network using Command Line (SSH) and HTTPS or via Command Line (SSH) using the console port. Remote configuration and maintenance are possible via TR-069 standard, and firmware updates can be carried out via SSH, HTTPS and TR-069. The router also offers SNMP and a Checkmk agent for comprehensive network management.

Overall, the NG2000-D 4G with its integrated 4G radio modem offers an innovative solution for companies that require a flexible, secure and reliable network connection, regardless of the availability of DSL connections.

Produkt Highlights

DSL modem

Thanks to the built-in DSL modem, the device can be connected directly to any DSL connection to establish an Internet connection. All common DSL standards (ADSL2/2+, VDSL2 including SuperVectoring - Profile 35b) are supported. This broad compatibility ensures seamless integration into existing networks and enables fast commissioning without time-consuming configuration.

Multi-protocol VPN

In contrast to many conventional routers, which often only support one VPN protocol, multi-protocol VPN offers a choice of different protocols. This makes it possible to choose the protocol that best meets individual requirements, for example OpenVPN, IPsec, IPsec/L2TP or WireGuard.

MultiWAN Manager

With the MultiWAN Manager, you always have the right connection. Whether via xDSL, LTE, WLAN or WAN - the MultiWAN Manager automatically ensures that your preferred connection type is always selected.

4G mobile radio

The integrated radio modem covers all common European frequency bands in the 2G, 3G and 4G range. Additional radio modems with country-specific frequencies are optionally available. In the event of a network failure, the system automatically switches over - the connection remains online


WireGuard is a very practical and modern solution for VPN applications - with the aim of being simpler than IPsec and better performing than OpenVPN. Available on almost all platforms, it is easy to use and therefore uncomplicated. WireGuard uses state-of-the-art cryptography and therefore benefits from protected communication using the latest technology. It is designed as a universal VPN for operation on everything from embedded devices to supercomputers.

Industrial quality steel housing

The housing sets standards for quality and safety right from the choice of materials, which you can literally feel with your hands. The housing is made of robust Zincor sheet metal with a thickness of one millimeter; it ensures excellent thermal conductivity, strength and high stability.
