I try to understand how to combinate implicit global ACL witch security level.
1) In documentation there are: Traffic from Higher Security Level to Lower Security Level: Allow ALL traffic originating from the higher Security Level unless specifically restricted by an Access Control List (ACL).
2) But in Cisco ASA, there is implicit default global access rule. Deny any any on all interface for incoming traffic.
Point 1) and 2) are in contradiction.
Can anybody explain it? Thank you.
