Understanding IPSec VPN Internet Protocol Security (IPSec) VPN secures traffic flowing between two networks connected over a public network through IPSec gateways called endpoints. NSX Edge only supports a tunnel mode that uses IP tunneling with Encapsulating Security Payload (ESP). Hi, I know how to configure site-to-site VPN tunnel but I just want to know what really happens during Phase 1 and 2. This can really help during troubleshooting. I understand that IKE phase 1 is used to establish IKE SAs. But I'm a little confused with the purpose of the Encryption and Hash funct IPSec Configuration. Overview of IPSec; Understanding IPSec. Basic Concepts of IPSec; IPSec Fundamentals; IPSec Enhancements; Application Scenarios for IPSec. IPSec Application in OSPFv3; Secure LAN Interconnection Through Efficient VPN; Summary of IPSec Configuration Tasks; Licensing Requirements and Limitations for IPSec; Default Settings for Pro: IPSec is flexible, widely supported and can be used in plenty of scenarios. Con: Implementation can become tricky; be sure to know the technology and have a clear understanding of your needs. Pro: IPSec provides security by encrypting, authenticating and optionally preventing replay attacks.

Network-based encryption is implemented using the IPsec protocol to establish Virtual Private Networks (VPNs). This can be performed by a software client running on an End User Device (EUD), by a dedicated hardware appliance (a VPN gateway), or as additional functionality in other networking infrastructure equipment (such as a router).

If your ike and ipsec connections are up your problem is likely a policy or routing problem. For route-based VPNs you generally just bind a ipsec tunnel to a interface, such as st0.0, then bind that interface to a zone, then build simple security policies, then make routes that point over that tunnel. IKEv1 Phase 1 SA negotiation is for protecting IKE. IKEv1 Phase 2 SA negotiation is for protecting IPSec (real user traffic). IKEv1 Phase 1 negotiation can happen in two modes, either using Main Mode or using Aggressive Mode. IKEv1 Phase 1 Main mode has three pairs of messages (total six messages) between IPSec peers.
