IPSec tunnel fails in phase 2. Ask Question Asked 3 years, 3 months ago. Active 3 years, 3 months ago. Viewed 5k times 1. 0. We are trying to establish a tunnel between our EC2 Instance and remote Cisco 3000 series device where it is failing for Phase2. Below is the scenario:

FortiGate IPSec Phase 1 parameters – Fortinet GURU IPsec Phase 1 settings define: The remote and local ends of the IPsec tunnel; If Phase 1 parameters are exchanged in multiple rounds with encrypted authentication information (main mode) or in a single message with authentication information that is not encrypted (aggressive mode) MikroTik Site-to-Site IPsec Tunnel | Saputra Mar 24, 2020 Use Mobile VPN with IPSec with an Android Device

IKE main mode, aggressive mode, & phase 2. | CCIE or Null!

IKEv1 Phase 1 and Phase 2 - VMware Phase 2 Parameters. IKE Phase 2 negotiates an IPSec tunnel by creating keying material for the IPSec tunnel to use (either by using the IKE phase 1 keys as a base or by performing a new key exchange). The IKE Phase 2 parameters supported by NSX Edge are: Triple DES, AES-128, AES-256, and AES-GCM [Matches the Phase 1 setting]. SHA1, SHA_256. Networking Fundamentals: IPSec and IKE - Cisco Meraki

The IPsec SA is valid for an even shorter period, meaning many IKE phase II negotiations take place. The period between each renegotiation is known as the lifetime . Generally, the shorter the lifetime, the more secure the IPsec tunnel (at the cost of more processor intensive IKE negotiations).
