Does strongSwan support IKEv1?
If you use IKEv1, you need to be a roadwarrior and use the UNITY extension. strongSwan implements it with the unity plugin.
Is IKEv1 deprecated?
Deprecating IKEv1 IKEv1 is deprecated and MUST NOT be deployed. Systems running IKEv1 should be upgraded and reconfigured to run IKEv2. Systems that support IKEv1 but not IKEv2 are most likely also unsuitable candidates for continued operation.
Does IKEv1 support DH Group 14?
The AWS GOV cloud requires the use of IKEv1 with DH-Group 14. However this is not possible to do on the ASA with IKEv1. You can use IKEv2 with DH group 14 but AWS GOV CLOUD config file shows IKEv1 must be used.

What is Mobike in strongSwan?
The MOBIKE IKEv2 extension (RFC 4555) allows an initiator to change its network attachement point (e.g. roam to an other interface/address). strongSwan implements MOBIKE by watching interfaces, addresses and routes.
Which is better L2TP or IKEv2?
IKEv2 is not as common as L2TP/IPSec as it is supported on many fewer platforms (although this situation is changing fast). It is, however, considered at least as good as, if not superior to, L2TP/IPsec in terms of security, performance (speed), stability and the ability to establish (and re-establish) a connection.
Which is better IKEv1 or IKEv2?
IKEv2 is better than IKEv1. IKEv2 supports more features and is faster and more secure than IKEv1. IKEv2 uses leading encryption algorithms and high-end ciphers such as AES and ChaCha20, making it more secure than IKEv1. Its support for NAT-T and MOBIKE also makes it faster and more reliable than its predecessor.
Why is IKEv1 not secure?
The researchers found that IKEv1 is vulnerable to Bleichenbacher oracle attacks, a cryptographic attack technique that has been known for almost two decades. A Bleichenbacher attack involves sending modified ciphertext to a device and obtaining information about its unencrypted value based on the device’s response.
What is Mobike in IKEv2?
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.
What is Mobile Ike?
IPsec uses the Internet Key Exchange (IKE) protocol for these functions. IKE is a protocol for providing mutual authentication and security association establishment for IPsec VPNs.
What is the difference between IKEv2 IPSec and L2TP?
strongSwan is an IKE daemon with full support for IKEv1 and IKEv2. It is natively supported by most modern clients, including Linux, Windows 7, Apple iOS, Mac OSX, FreeBSD and BlackBerry OS.
What is DPD strongSwan?
strongswan – DPD timeout defines the timeout interval, after which all connections to a peer are deleted in case of inactivity. This only applies to IKEv1, in IKEv2 the default retransmission timeout applies, as every exchange is used to detect dead peers.
What port does strongSwan use?
VM or Server that runs strongSwan is healthy and has no known issues. There is root access to the strongSwan instance. Your on-premises firewall allows UDP port 500, UDP port 4500, and ESP packets. You should be able to configure your on-premises router to route traffic through strongSwan VPN gateway.
