My IKEv1 captures looks like that: (Note the Flow Graph for a better understanding of the directions. - Configure IKEV1 or 2 phase 1. /24 right=NameOfYourServer. IKEv2 is my VPN protocol of choice (or more strictly, the key exchange protocol which configures IPsec tunnels for me). A tunnel using IKEv1 can only carry the same protocol traffic in Phase 2 as was used for Phase 1. IKEv1 consists of two phases: phase 1 and phase 2. The Security Associations (SAs) negotiated in Phase 1 is then used to protect future IKE communication. • IKEv1 Phase 2. --> IKEV2 is more scalable by using proposals which automatically creates the different combinations of policies or security associations. Result: ( Phase II) security Phase -2 Troubleshooting Steps, Site to site IPSec Follow me on all of 1. For the “Local Policy”, choose the subnet on your USG to which the VPN clients are supposed to have access to. There are technical limitations and scalability challenges with phase 2, as it Traditionally, most of us are probably used to dealing with IKEv1 and IPsec in conjunction with DMVPN. [Applicable Models]. Phase 1: IKE policy. In Phase 1, single bi-directional SA (Security Association) is created between VPN peers and is a control channel for Phase-1 keepalives, DH-Key Calculation and Phase-2 SA creation and rekey. In both phases Internet Security Association and Key Management Protocol (ISAKMP) and IPSec are. In phase 1 an ISAKMP SA is established that is used in phase 2 to set up an IPsec SA. conn BOT keyexchange=ikev1 It looks like strongswan is the initiator so it's strange that the initiator is up but the responder rejects the phase 2 SA for some. Many vulnerabilities in IKEv1 were fixed. 2 Configuring the Advanced Parameters Advanced settings include IKEv1 phase-1 settings and IKEv1 phase-2 settings.
