WebJul 20, 2024 · During an Internet Key Exchange Version 2 (IKEv2) connection set up, the initiator is never aware of what proposals are acceptable by the peer, so the initiator must guess which Diffie-Hellman (DH) group to use when the first IKE message is sent. The DH group used for this guess is usually the first DH group in the list of DH groups configured.
