I'm trying to allow traffic between 2 VLAN's/sub interfaces on my ASA, the both have their security Level set at 25. At the moment I can't even ping devices between the 2 and my access lists are wide open. I raised one of the security groups to 35 and everything seem to work.
I'm left a little confused, if security levels are the same are the untrusted? What ever I did on the access list side (to open it up) seemed to be ignored.
