ID/Pswd encryption, Phase 1 vs Phase 2

ronald_beaulieu · ‎11-26-2001

Hello,

We have a VPN-3015, can someone tell me where i can find the description of how the Phase 1 and Phase 2 authentications take place and if the id/pswd encryption are the same for both phases?

Thanks in advance.

Ronald.

Phase 1 setup the IKE and it uses your vpngroup password as the pre-shared key for encryption. Phase 2 setup the IPSec security association, and it is based on what ever is negotiated on phase 1. See
