• Modular software structure
  The modular software structure offers the option of integrating customised/custom-developed software.
• DHCP (Dynamic Host Configuration Protocol)
  A communication protocol that enables clients to retrieve and servers to assign the network configuration (client/relay/server)
• Protocols
  z. E.G. IP, TCP, UDP, PPP, ARP, RARP, ICMP
• DNS (Domain Name System)
  It manages the name space in networks, e.g. for converting 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 synchronisation via networks (client/server)
• Routing
  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 prioritising data packets to meet the quality standard, especially for time-critical transmissions/applications
• Real-time statistics and log function
• Syslog client

• TPM (Trusted Platform Module)
  The TPM chip is comparable to a permanently installed smart card. The TPM protects cryptographic keys; these can be generated, used and securely stored within the TPM. It offers 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 the basis for securely encrypted communication.
• Firewall
  Zone-based stateful inspection firewall (IPv4/IPv6) with packet filter and demilitarised zone (DMZ);
  Bridging firewall
• OpenVPN
  Free software based on OpenSSL for setting up a secure VPN via an encrypted connection. Both routed and bridged tunnels (client/server) are supported.
• IPSec
  Internet Protocol Security: for secure VPN communication via potentially insecure
• L2TP (Layer 2 Tunneling Protocol), passthrough
  Tunnelling protocol for transmitting the data link layer (Layer 2) of the OSI model between two networks
• WireGuard
  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 is executed on the server side as a Linux kernel module. WireGuard uses only public keys for identification and encryption and can therefore dispense with a certificate infrastructure.
• Hash algorithms
  MD5, SHA1, SHA2 256/512
• Diffie Hellman Groups
  Schlüsselaustausch zum Sichern: 1, 2, 5, 14, 15, 16, 17, 18
  Modulo Prime Groups with Prime Order Subgroup: 22, 23, 24
  NIST Elliptic Curve Groups: 25, 26, 19, 20, 21
  Brainpool Elliptic Curve Groups: 27, 28, 29, 30
• Encryption algorithms
  AES 128/192/256, Blowfish, Twofish 128/256, Serpent 128/256
• Number of VPN tunnels
  The number of configurable VPN tunnels is not limited by the software. Depending on the application, up to
  - 30 VPN tunnels (VR2020 series),
  - 400 VPN tunnels (G3000 & G4000 series) and
  - 5000 VPN tunnels (G5000 series) are possible.

• MultiWAN manager with complex backup options
  - Multihomed and multi-level backup target strategies
  - Optimisation of switchover times
  - Prevention of unnecessary switching
  - Optimisation of switchback
  - Prevention of switching instabilities (fluttering)
  - Mobile telephony: Provider switching with MultiSIM
  - Dynamic connection parameters (default route, policy-based routes, etc.)
  - Configurable connection check (ping, LCP echo, etc.)
• VRRP (Virtual Router Redundancy Protocol)
  - With support for Multi group VRRP

• Management/configuration
  Via the network using Command Line (SSH) and HTTPS as well as via Command Line (SSH) using the console port
• Remote configuration/maintenance
  If required, remote configuration/maintenance can be carried out using the TR-069 standard. Configuration via TDT C.O.R.E. is also possible.
• Firmware update
  Firmware updates can be realised via SSH, HTTPS and (TR-069).
• SNMP (Simple Network Management Protocol)
  SNMP is a network protocol that was developed to monitor and control network elements from a central station.
• Checkmk agent
  For connection to the Checkmk network management system

• Processor
  Powerful hexa-core processor
• Memory
  16GB DDR4 RAM
• Hard disc
  240GB SSD (SolidStateDisk)
