IPSec VPN Negotiations - Phase 1 and 2 ~ Peter Manton
Jul 24, 2017 · Phase 2. In this phase, the negotiation is protected between the two peers thanks to the ISAKMP SA that's already been established and the end goal of this phase is to have two unidirectional channels between the peers set up to pass traffic in a secure manner over an insecure network. This phase uses something called Quick Mode to establish IKEv2 corresponds to Main Mode or Phase 1. IPsec corresponds to Quick Mode or Phase 2. DH Group specifies the Diffie-Hellmen Group used in Main Mode or Phase 1. PFS Group specifies the Diffie-Hellmen Group used in Quick Mode or Phase 2. IKEv2 Main Mode SA lifetime is fixed at 28,800 seconds on the Azure Stack Hub VPN gateways. The following For a managed Branch Office VPN, you configure the Phase 1 and Phase 2 settings when you add a Security Template. For more information, see Add Security Templates. Mobile VPN with IPSec. For Mobile VPN with IPSec, Mobile VPN with L2TP, and Mobile VPN with IKEv2, many of the Phase 1 and Phase 2 settings are set automatically by the setup wizards.

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.

Dec 31, 2014 · Phase 2 is using the SHA-1 hashing algorithm. Phase 2 is using AES-128as the encryption algorithm (but see below). Perfect forward secrecy (PFS) is enabled and using Diffie-Hellman Group 2 for key generation. Enhanced AWS VPN endpoints support some additional advanced encryption and hashing algorithms, such as AES 256, SHA-2(256), and DH groups Nov 23, 2011 · Hi All, I have a question. Is that a big problem to have different Phase 2 lifetimes configured on L2L VPN tunnels on both ends? Like one end has P1 lifetime set to 86400 P2 lifetime set to 86400 and remote end has P1 set to 86400 and P2 set to 28800. Thanks!
