# AutoKey IKE P2 Proposal List

Setting up the VPN tunnel encryption and authentication is actually a two-phase process.

- Phase 1 essentially covers how the gateways will securely negotiate and handle the building of the tunnel. The P1 (Phase 1) Proposal sets the terms of the negotiation.

- Phase 2 sets up how the data passing through the tunnel will be encrypted at one end and decrypted at the other. The encryption method you choose needs to account for both phases. This process is carried out on both sides of the tunnel. The P2 (Phase 2) Proposal sets the terms of the negotiation.
