The major functional benefit of IKEv2, over L2TP/IPsec VPNs, is that L2TP only allows one source IP per client, while IKEv2 has no limit. If you have say, three Windows laptops all on the same internet connection (hotel WiFi or hotspot) trying to connect into the company VPN, only the most recent connection will remain live — just one laptop
Jun 22, 2020 · In IKEv2 VPN implementations, IPSec provides encryption for the network traffic. IKEv2 is natively supported on some platforms (OS X 10.11+, iOS 9.1+, and Windows 10) with no additional applications necessary, and it handles client hiccups quite smoothly. In this tutorial, you’ll set up an IKEv2 VPN server using StrongSwan on an Ubuntu 20.04 asa1(config)#crypto map ikev2-map 1 match address ikev2-list. 17. Configure the peer IP address. asa1(config)#crypto map ikev2-map 1 set peer 10.10.10.2. 18. Assign the previously created proposal. asa1(config)#crypto map ikev2-map 1 set ikev2 ipsec-proposal ikev2-proposal. 19. Apply the crypto map to an interface. Internet Key Exchange version 2 (IKEv2) is an IPsec based tunneling protocol that provides a secure VPN communication channel between peer VPN devices and defines negotiation and authentication for IPsec security associations (SAs) in a protected manner. Understanding Internet Key Exchange Version 2
IKEv1 vs IKEv2 “IKE,” which stands for “Internet Key Exchange,” is a protocol that belongs to the IPsec protocols suite. Its responsibility is in setting up security associations that allow two parties to send data securely.

This conclude this article on IPsec/IKEv2 configuration between a Cisco CSR 1000v and a gateway running OpenBSD's OpenIKED.
Jun 26, 2020 · IPsec remote access VPN using IKEv2 requires an AnyConnect Plus or Apex license, available separately. IPsec remote access VPN using IKEv1 and IPsec site-to-site VPN using IKEv1 or IKEv2 uses the Other VPN license that comes with the base license. See Cisco ASA Series Feature Licenses for maximum values per model. Restrictions for IPsec VPN
IKEv2/IPSec PSK for authentication of both client and server with a pre-shared key (PSK), which is not an ideal choice for remote access connections as anybody who knows the PSK can impersonate the server (an active attacker can retrieve the PSK hash and attack it via brute-force/dictionary attack). DHGroup2048 & PFS2048 are the same as Diffie-Hellman Group 14 in IKE and IPsec PFS. See Diffie-Hellman Groups for the complete mappings. For GCMAES algorithms, you must specify the same GCMAES algorithm and key length for both IPsec Encryption and Integrity. IKEv2 Main Mode SA lifetime is fixed at 28,800 seconds on the Azure VPN gateways.
