Connection via VPN IPsec

Requirements for the VPN end device

When creating a connection to oneclick™, please note that a connection to an external firewall vendor/manufacturer is established here. We do not use a specific vendor, but regulate VPN connections via an IPsec technology.

  • A site-to-site connection must be possible.
  • The connection must not be triggered by the terminal device (response/passive mode). The connection is initiated by oneclick™.
