IPSec Site-to-Site VPN RB1000 to Customer Cisco ASA

I think, this is the solution:
http://forum.mikrotik.com/t/mikrotik-3-14-and-ipsec-problem-solved/23727/2

Second Problem:
As long as there is no data traffic through the tunnel, cisco disconnects phase 1, but Mikrotik does not flush installed SAs (phase 2).
So a connection through the tunnel is not possible and the tunnel is not rebuild until I flush installed SAs manually.

Any Idea?

thanks
