Functions and features
The VPN router - VR2020-LD with VDSL/ADSL and mobile radio - is manufactured according to the highest quality standards and is ideally suited for setting up secure branch networks or connecting mobile ATMs due to its high flexibility.
The VR2020-LD achieves high-speed Internet access with extremely high reliability through intelligent backup management and the use of two SIM cards (dual SIM support).
To enable the router to be operated on all modern DSL connections, including all-IP, the VR2020-LD has an integrated DSL modem that supports the ADSL/2/2+ and VDSL/VDSL2 standards as well as VDSL2 vectoring. The 2G, 3G and 4G radio connection is established via a multiband modem that supports the LTE (= Long Term Evolution), HSPA+, HSDPA/HSUPA, UMTS, EDGE and GPRS standards. The Ethernet WAN port allows both the realisation of any gateway connections and the connection of external modems (e.g. SDSL, cable, FTTH).
A VR2020-LD router can be easily integrated into a branch network or connected to a head office via a permanently established VPN tunnel and can thus be reached directly 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 either by means of stored certificates or pre-shared keys. The VPN router supports all modern encryption algorithms such as AES with up to 256-bit key length.
When it comes to security, the integrated Trusted Platform Module (TPM), which is used for the secure storage of secret keys, should also be highlighted. Cryptographic keys can be generated, used and securely stored within the TPM with the support of the integrated and secure random number generator (RNG). The Trusted Platform Module offers protection against software attacks as well as hardware manipulation.
A configurable high-security firewall is available to protect your network against attacks. This can be easily adapted to your individual requirements by rules and scripts.
The VPN router can be conveniently configured - both locally and remotely - via the intuitive web interface. Experts can also manage the VR2020-LD via command line (SSH).
For use in branch networks, automated remote configuration/maintenance via TDT C.O.R.E. is ideal, as is monitoring via a network management system such as Checkmk.
All features in detail
- Modular software structure
The modular software structure offers the possibility to integrate customer-specific/customer-developed software.
- DHCP (Dynamic Host Configuration Protocol)
A communication protocol that allows clients to retrieve and servers to assign the network configuration (client/relay/server)
z. B. IP, TCP, UDP, PPP, ARP, RARP, ICMP
- DNS (Domain Name System)
It manages the namespace in networks, e.g. for the conversion of domain names into IP addresses (client/relay/server).
- Dynamic DNS
Dynamic DNS: It is used to dynamically update the IP address of a computer so that it can always be reached under the same name.
- NTP (Network Time Protocol)
Standard for time synchronization over networks (client/server)
Static Routing (IPv4 Forwarding)
Static Routing (IPv6 Forwarding)
Policy-based routing (PBR)
- NAT (Network Address Translation)
Source and Destination NAT/NAPT and Masquerading
- QoS (Quality of Service)
For prioritizing data packets to meet quality standards, especially for time-critical transmissions/applications
- Real-time statistics and log function
- TPM (Trusted Platform Module)
The TPM chip is comparable to a fixed smart card. The TPM protects cryptographic keys; these can be generated, used and securely stored within the TPM. It provides protection against software and hardware attacks (physical manipulation results in the destruction of the stored keys). In addition, the integrated random number generator (RNG) provides secure number sequences as a basis for securely encrypted communication.
Zone based Stateful Inspection Firewall (IPv4/IPv6) with Packet Filter and Demilitarized Zone (DMZ);
Free software based on OpenSSL for building a secure VPN over an encrypted connection. Both routed and bridged tunnels (client/server) are supported.
Internet Protocol Security: for secure VPN communication over potentially insecure IP networks. IKEv1/IKEv2/MOBIKE (client/server and IPSec passthrough) are supported.
- L2TP (Layer 2 Tunneling Protocol), passthrough
Tunnel protocol for transferring the security layer (layer 2) of the OSI model between two networks
WireGuard uses the latest, particularly powerful cryptographic algorithms, e.g. the Noise Protocol Framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24 or HKDF. WireGuard gets a further performance boost from the fact that the software runs as a Linux kernel module on the server side. WireGuard uses only public keys for identification and encryption and can therefore do without a certificate infrastructure.
