TL;DR use OpenVPN ECC with our software for best speed and security mix. If you're connecting from a firewall-restricted network, try OpenVPN XOR with port TCP-443. Avoid PPTP and even L2TP/IPsec. OpenVPN 256-bit AES is kind of overkill, rather use AES 128-bit. Jul 10, 2020 · OpenVPN is not the best protocol out there in terms of performance. It is considerably slower than its earlier counterparts i.e. L2TP and PPTP, but this difference wasn’t really important until multi-threaded processing became practical.However, computers today are capable of supporting multi-threaded processing and higher throughput. L2TP/IPsec is an excellent choice if OpenVPN is not available on your device, but you want more security than PPTP. OpenVPN is an open source VPN software developed by 'OpenVPN technologies' . OpenVPN is the recommended protocol for desktops, including Windows, Mac OS X, and Linux. Many are considered obsolete and not secure, which is why they are rarely used – like PPTP or L2TP, which we do not offer in any of our apps. VPN protocol vs. tunneling protocol A tunneling protocol is simply a way to transfer information from point A to point B. OpenVPN vs L2TP Layer 2 Tunnel Protocol (L2TP) is a VPN protocol that doesn’t offer any encryption. That’s why it’s usually implemented along with IPsec encryption. OpenVPN, which uses the OpenSSL library for encryption and authentication, is reasonably fast, very secure, open source, and can traverse NAT firewalls. It can support either the UDP or TCP protocol. IKEv2/IPSec presents a new challenger to OpenVPN, improving on L2TP and other IPSec-based protocols with faster connections, more stability, and
2. IKEv2 / L2TP / PPTP . In the event that OpenVPN or SSL faces difficulty in connecting or does not appear to work very well with your network, we recommend that you give IKEv2 a try, which connects fast and are known to be more stable on mobile networks compared to the other protocols.
Dec 16, 2015 · L2TP/IPsec is also primarily used on iOS by VPN providers as a worthy alternative to OpenVPN (iOS has API restrictions that prevent OpenVPN from being an option while Android doesn’t). L2TP provides strong 256-bit encryption sessions but has slower speeds than PPTP and OpenVPN. Pros. High-security rating. Works on iOS. Cons. Slower than
Jul 01, 2014 · OpenVPN has a more secure implementation (Userspace vs Kernel). It works better with Firewalls and NAT (no need to ensure NAT-T) and is difficult to filter. It is a lot less complicated then IPsec. The biggest disadvantage to OpenVPN is that it's not interoperable with the vast majority of products from "big name" network vendors out there.
Compare PPTP, IPSec IKEv2, OpenVPN and WireGuard to determine which VPN protocol offers the best combination of security, speed and ease of use for your needs.
