VPNarchitecturen

VPNarchitekturen, or VPN architectures, refer to the design and implementation strategies for setting up and managing Virtual Private Networks. These architectures dictate how VPNs are deployed, how users connect, and how data is secured and routed between different network locations. A fundamental aspect of VPN architecture is the choice of VPN protocol, such as OpenVPN, IPsec, or WireGuard, each offering different levels of security, performance, and compatibility.

Common VPN architectures include site-to-site VPNs, which connect entire networks, like two office branches, and remote access VPNs, which allow individual users to securely connect to a private network from external locations. The architecture also encompasses the placement of VPN gateways, which act as endpoints for the VPN tunnel, and the methods used for authentication and encryption. Considerations such as scalability, redundancy, and the management of IP addresses are integral to a well-designed VPN architecture. The overall goal is to create a secure, reliable, and efficient private network extension over public infrastructure.
