My checkpoint NG is FP1 and the other site is FP2. I double checked the enc. alg., method, data integrity, etc... Everything is the same with the other node. 3DES, MD5, DH Group 2. We use pre-shared secret key. When I look at the logs, I get the message "IKE: Main Mode Sent Notification: no proposal chosen". What can be the reason? Any ideas???
