Global ACL on Cisco ASA Version 8.3+

Postby admin » Tue May 01, 2012 3:12 pm

Cisco ASA running Version 8.3 introduces the concept of a Global ACL. At first I thought this was great, until I found out there is NOT an implicit deny at the end of the ACL. If a Deny is not added to the end of the Global ACL, it relies on an ACL on the interface to provide the implicit deny. If you do not have ACL's at the interface level, then the firewall passes everything.
