I believe that your issue is that you apply weight of 255 for your default route.
route outside 0.0.0.0 0.0.0.0 85.84.102.185 255
Try applying some lower weight and tell us if the behavior changes.

Thank You Richard for Your help. Yesterday afternoon we found where is problem. There was a MAC pairing on external router. When I changed Siemens Scalance to Cisco ASA, with the same configuration, I lost connection. Today I'll make additional test to confirm if configuration is OK.

Thank you for the additional information. The MAC pairing may well be part of the problem. I continue to believe that the weight applied to the default route is also part of the problem. Please do let us know the results of your additional testing.
