Installing the NordVPN OpenVPN application on macOS This article is available in French, German, Italian, Swedish, and Dutch. The first step towards online security is setting up NordVPN correctly. OpenVPN is a full-featured SSL VPN solution which can accomodate a wide range of configurations, including remote access, site-to-site VPNs, WiFi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls (articles) (examples) (security overview) (non-english languages). Download the app. Firstly, go to the official Tunnelblick website. Click the green arrow to download the latest Tunnelblick version. Locate the installation package in the Downloads or Recents folder on your Mac. Install the app. To start the installation process, double-click on the Tunnelblick installation package that is in your Downloads.

OpenVPN is a robust and highly flexible VPN daemon. OpenVPN supports SSL/TLS security, ethernet bridging, TCP or UDP tunnel transport through proxies or NAT, support for dynamic IP addresses and DHCP, scalability to hundreds or thousands of users, and portability to most major OS platforms.

OpenVPN is tightly bound to the OpenSSL library, and derives much of its crypto capabilities from it.

OpenVPN supports conventional encryption using a pre-shared secret key (Static Key mode) or public key security (SSL/TLS mode) using client & server certificates. OpenVPN also supports non-encrypted TCP/UDP tunnels.

OpenVPN is designed to work with the TUN/TAP virtual networking interface that exists on most platforms.

Overall, OpenVPN aims to offer many of the key features of IPSec but with a relatively lightweight footprint.

With OpenVPN, you can:

  • tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port,
  • configure a scalable, load-balanced VPN server farm using one or more machines which can handle thousands of dynamic connections from incoming VPN clients,
  • use all of the encryption, authentication, and certification features of the OpenSSL library to protect your private network traffic as it transits the internet,
  • use any cipher, key size, or HMAC digest (for datagram integrity checking) supported by the OpenSSL library,
  • choose between static-key based conventional encryption or certificate-based public key encryption,
  • use static, pre-shared keys or TLS-based dynamic key exchange,
  • use real-time adaptive link compression and traffic-shaping to manage link bandwidth utilization,
  • tunnel networks whose public endpoints are dynamic such as DHCP or dial-in clients,
  • tunnel networks through connection-oriented stateful firewalls without having to use explicit firewall rules,
  • tunnel networks over NAT,
  • create secure ethernet bridges using virtual tap devices, and
  • control OpenVPN using a GUI on Windows or Mac OS X.

Important Notices

BF-CBC Cipher is no longer the default

Openvpn For Mac Os

  • Cipher handling for the data channel cipher has been significantly changed between OpenVPN 2.3/2.4 and v2.5, most notably there are no “default cipher BF-CBC” anymore because it is no longer considered a reasonable default. BF-CBC is still available, but it needs to be explicitly configured now.
  • For connections between OpenVPN 2.4 and v2.5 clients and servers, both ends will be able to negotiate a better cipher than BF-CBC. By default they will select one of the AES-GCM ciphers, but this can be influenced using the –data-ciphers setting.
  • Connections between OpenVPN 2.3 and v2.5 that have no –cipher setting in the config (= defaulting to BF-CBC and not being negotiation-capable) must be updated. Unless BF-CBC is included in –data-ciphers or there is a “–cipher BF-CBC” in the OpenVPN 2.5 config, a v2.5 client or server will refuse to talk to a v2.3 server or client, because it has no common data channel cipher and negotiating a cipher is not possible. Generally, we recommend upgrading such setups to OpenVPN 2.4 or v2.5. If upgrading is not possible we recommend adding value='https://www.techspot.com/downloads/5182-openvpn/similar/'>
