Which is better OpenVPN or IKEv2?
Performance: In many cases IKEv2 is faster than OpenVPN since it is less CPU-intensive. There are, however, numerous variables that affect speed, so this may not apply in all use cases. From a performance standpoint with mobile users, IKEv2 may be the best option because it does well establishing a reconnection.
Which is better IKEv2 or IPsec?
IPSec is considered secure and reliable, while IKEv2 is extremely fast and stable – IKEV2 offers quick re-connections when switching networks or during sudden drops. Thus, a combination of IKEv2/IPsec forms one of the best VPN protocols that exhibits the advantages of the two.
What is IKEv2 Mobike?
IKEv2 Mobility and Multi-homing Protocol (MOBIKE) allows the IP addresses associated with IKEv2 and tunnel mode IPSec Security Associations (SA) to change. A mobile Virtual Private Network (VPN) client could use MOBIKE to keep the connection with the VPN gateway active while moving from one address to another.
Does OpenVPN use IPsec?
OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent implementation of IPSec.

What is the phase 1 of IKEv2?
With the IPsec IKEv2 protocol, the establishment of the connection is also divided into two phases, phase 1 will perform the authentication, and phase 2 will negotiate the encryption of the tunnel with symmetric cryptography for the exchange of information.
Which is more secure, IKEv1 or IKEv2?
In this case, we will use the IKEv2 protocol, which is a more secure protocol than IKEv1 for data encryption negotiation between the different clients and the server, in addition, we create a PSK-based authentication to authenticate the clients. Within the IPsec IKEv2 protocol, we have two authentication methods:
Is IKEv2 better than VPN?
Although IPsec IKEv2 performs better than other types of IPsec-based VPN in terms of compatibility, we must pay special attention to the encryption algorithms that we put in the VPN server, because it could cause some IPsec clients to be unable to connect. This is quite common with the IPsec protocol, because we depend on what IPsec client software ...
