How to change Phase 1 policy for a Site to site VPN.
To my understanding you can't choose a certain Phase1 parameters for the VPN connection. (Atleast I'm under the impression. If it's possible I would be interested too)
What you can change though is the order of your ISAKMP policys. As you have mentioned
The smaller the sequence number, the higher on the list it should be. When your ASA starts negotiation with another peer it should offer the first policy or compare the peers "suggestion" to your first policy.
