Internet Key Exchange for IPsec VPNs Configuration Guide

The resulting tunnel is a virtual private network or VPN. IKE manages the authentication between two communicating end points. It also enables endpoints to negotiate on algorithms to use to setup an IPsec tunnel. In our previous guide, we covered how to install and configure IPSec VPN using StrongSwan on Ubuntu 18.04. See the link below; Create a Route Based Azure VPN with Custom IPsec Create a virtual network and a VPN gateway; Create a local network gateway for the cross-premises connection; Create a connection (IPsec) with the standard IPsec/IKE policy; Add an IPsec/IKE policy with selected algorithms and parameters; View/remove an IPsec/IKE policy … Set Up an IPSec Tunnel - docs.paloaltonetworks.com

In enabled previously, the 'Automatic Firewall/NAT' checkbox adds the following rules to the iptables firewall in the background:. UBNT_VPN_IPSEC_FW_HOOK Allow UDP port 500 (IKE), UDP port 4500 (NAT-T) and ESP in the local direction.; UBNT_VPN_IPSEC_FW_IN_HOOK Allow IPsec traffic from the remote subnet to the local subnet in the local and inbound direction.

IKE Phase II (Quick mode or IPSec Phase) IKE phase II is encrypted according to the keys and methods agreed upon in IKE phase I. The key material exchanged during IKE phase II is used for building the IPsec keys. The outcome of phase II is the IPsec Security Association. IPSec and VPNs IPSec is defined by the IPSec Working Group of the IETF. It provides authentication, integrity, and data privacy between any two IP entities. Management of cryptographic keys and security associations can be done manually or dynamically using an IETF-defined key management protocol called Internet Key Exchange (IKE). How to check Status, Clear, Restore, and Monitor an IPSEC

IPsec and IKE policy parameters for VPN gateways The IPsec and IKE protocol standard supports a wide range of cryptographic algorithms in various combinations. To see which parameters are supported in Azure Stack Hub so you can satisfy your compliance or security requirements, see IPsec/IKE parameters.
