Hello,

I am trying to interoperate Strongswan, (open source IPSec client) with ASA.
However I am getting the following error for the CHILD_SA establishment.
I am using pre-shared key for authentication. I have tried all possible combination for encryption/hash/DH group
Any pointers appreciated.   


ASA console
