It is obvious that China Telecom is specifically throttling OpenVPN traffic to that specific server. There is nothing unusual about that. What I find unusual is that it is normally the other way around, the IKEv2 traffic is throttled instead of OpenVPN. Next, I decided to compare some other servers using IKEv2 on the iPad vs OpenVPN on my computer.

IKEv2/IPsec (the latest addition in NordVPN protocols) is also protected by IPsec, just as L2TP is, however IKEv2/IPsec significantly increases security and privacy of the user by employing very strong cryptographic algorithms and keys. NordVPN uses NGE (Next Generation Encryption) in IKEv2/IPsec. The ciphers used to generate Phase1 keys are AES-256-GCM for encryption, coupled with SHA2-384 to OpenVPN to najnowszy, oparty w pełni o rozwiązania open-source protokół umożliwiający łączenie się z VPN. Jego podstawowa funkcjonalność opiera się o bibliotekę OpenSSL i protokoły SSLv3 oraz TLSv1. W odróżnieniu od IKEv2 i L2TP/IPSec, do szyfrowania nie jest wykorzystywany IPSec, tylko wspomniany wcześniej SSL i TLS. OpenVPN IKEv2 / IPsec . Wie bereits erwähnt, spielt die Authentifizierung eine wichtige Rolle bei der Funktionsweise aller VPNs. Jede Sitzung, die Sie im sicheren Tunnel öffnen, wird Ihren Geräte- und Benutzerinformationen zugewiesen, sodass Webanforderungen an Ihr lokales Netzwerk weitergeleitet werden können. L2TP war die erste Authentifizierungsmethode, die mit dem IPSec Overall, OpenVPN is the most secure protocol available and while it is not as easy to set up, it should be the first choice whenever possible. PPTP offers simple setup and L2TP/IPsec is compatible with a wide range of platforms and devices. However, they are not as secure as OpenVPN and are likely to have been compromised by the NSA. SSTP is a 27/12/2018 IKEv2 stands for Internet key exchange version two, and IPSec refers to the Internet protocol security suite. Together, they form a VPN protocol. A VPN protocol, or a “tunneling protocol,” is the set of instructions your device uses to negotiate the secure encrypted connection that forms the network between your […] For example, if you use NordVPN, WireGuard is only available on Linux, while macOS users can choose between IKEv2/IPSec and OpenVPN. So it’s worth it to know how the protocols differ so you’d choose the right one when you have that option. 1. OpenVPN . OpenVPN is the godfather of all VPNs. It’s a well-designed and reliable open-source software that forms the backbone of many VPN services

Sep 5, 2019 IPSec/IKEv2. IPSec/IKEv2. IKEv2 sets the foundation for a secure VPN connection by establishing an authenticated and encrypted connection. It 

OpenVPN vs IKEv2 vs PPTP vs L2TP/IPSec vs SSTP - Ultimate Guide to VPN Encryption Category: Guides Last Updated: June 30, 2020 Comments: 29. Written by Douglas Crawford. A Virtual Private Network (VPN) encrypts all data as it travels between your computer IPSec / IKEv2 are so customizable I have a hard time believing that OpenVPN can support any cipher suite that for example StrongSwan can't, I think the supported suit list is big enough x'D. I guess the more problematic issue here are the claims that NSA has been trying to weaken the standard from the beginning . IKEv2/IPsec VS OpenVPN IKEv2/IPSec is one in a long line of protocols , each building and expanding upon the strengths of predecessors. Where early options like Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP/IPsec) struggled to balance both speed and security, their successor, OpenVPN, excelled on both fronts.

Now, I have 3 different protocols option like l2tp, ikev2 and openvpn. You can use l2tp / ipsec which is quite secure and works on all platforms 

In a nutshell, IKEv2 is an IPsec-based tunneling VPN protocol that provides a IKEv1 vs. IKEv2. IKEv2 offers support for remote access by default, thanks to its  Learn the difference between PPTP, L2TP/IPsec, OpenVPN, and Chameleon to decide which VPN protocol is best for you. Are you confused by VPN protocols such as PPTP, OpenVPN, and L2TP? Like L2TP/IPsec, IKEv2/IPsec is a combination of distinct tunneling protocols  Mar 30, 2020 SSTP supports up to 128 concurrent connections only regardless of the gateway SKU. IKEv2 VPN, a standards-based IPsec VPN solution. IKEv2
