cjdns features and specs

  • Security
    cjdns uses cryptographic security for node communication, ensuring that all data transmitted is encrypted and secure from unauthorized interception.
  • Decentralization
    The network is designed to be decentralized, reducing reliance on central authorities and single points of failure, which enhances resilience and censorship resistance.
  • Scalability
    cjdns aims to improve scalability with a routing algorithm that scales logarithmically, which helps in maintaining performance as the network grows.
  • IPv6 Support
    cjdns natively supports IPv6, which allows for a vast address space and facilitates better compatibility with modern network infrastructures.
  • Mesh Networking
    cjdns supports mesh networking, allowing nodes to connect directly to each other without needing a central point, which can improve redundancy and coverage.

Possible disadvantages of cjdns

  • Complexity
    Setting up and maintaining a cjdns network can be complex and challenging for users who are not experienced with networking and cryptography.
  • Limited Adoption
    As of now, cjdns has limited adoption compared to traditional Internet infrastructure, which might hinder connectivity and resource availability.
  • Performance Overhead
    The encryption and routing mechanisms may introduce performance overhead, potentially affecting speed and latency compared to direct, unencrypted connections.
  • Interoperability
    Integration with existing Internet services and infrastructure can be challenging, as cjdns operates differently from traditional IP-based networks.
  • Resource Requirements
    Running a cjdns node can require substantial system resources, especially in larger networks, which might not be feasible for devices with limited capacity.

OpenVPN features and specs

  • Security
    OpenVPN uses robust encryption standards like AES-256, providing a high level of security for data transmission.
  • Open Source
    Being open-source, OpenVPN allows users to verify its code for vulnerabilities, ensuring transparency and reliability.
  • Flexibility
    OpenVPN can run on various platforms, including Windows, Mac, Linux, iOS, and Android, offering extensive compatibility.
  • Customizability
    Users can configure OpenVPN according to their specific needs, allowing advanced network setups and policies.

    OpenVPN offers strong performance with efficient handling of large data transmissions and support for high and stable speeds.
  • Community Support
    A large and active community provides ample resources, including tutorials, forums, and user support.
  • Cost
    As a free and open-source solution, OpenVPN significantly reduces the cost compared to many commercial VPN offerings.

Possible disadvantages of OpenVPN

  • Complex Setup
    Setting up OpenVPN can be complex and may require technical expertise, particularly for advanced configurations.
  • Resource Intensive
    OpenVPN can be resource-intensive compared to some other VPN protocols, potentially impacting the performance of older or lower-spec hardware.
  • Client Software
    The official OpenVPN client software has a less user-friendly interface compared to some commercial VPNs, possibly deterring less tech-savvy users.
  • Mobile Experience
    Although OpenVPN supports mobile devices, the user experience on mobile can be less streamlined compared to desktop environments.
  • Initial Learning Curve
    New users may find the initial learning curve steep due to the multitude of configuration options and the need for understanding networking concepts.
  • Support
    While community support is strong, there may not be as much immediate or personalized support as found with some commercial VPN services.

6 Types of VPN Protocols, Compared: Which is the Best to Use?
In most cases, OpenVPN or WireGuard will be your best bet. PPTP is a protocol we don’t recommend using because of its relatively low-level encryption. However, you could try this protocol when privacy and security are not your highest priorities, such as for unblocking streams. If OpenVPN is not supported or does not work well for whatever reason, you could consider using...

    I too haven't used the client-nat directive in some years (I currently implement 1:1 NAT with pfsense to access my network because I'm too lazy to change the networks subnet from the default) so I decided to retest and it does appear that OpenVPN Connect clients do not properly support the client-nat directive but the traditional OpenVPN server/clients still do.
