Any help on this would be greatly appreciated!!

You have applied an nonexistent acl to your inside interface, which blocks all traffic.

Hi Kvistofta
Any configuration suggestion on resolving my issue in an efficient way?
I'm just wondering if better to modify through command line or ASDM?

Thanks in advance for your help.

You have to define which traffic to allow from inside to internet. For testing allow .pl traffic:

Access-list inside_access_in permit ip any any
