Cisco ASA NAT and Access list (ACL) order of operation

Postby admin » Fri Jul 13, 2012 7:32 am

Before version 8.2 and earlier

1. ACL applied
2. NAT was performed

*The ACL would use the NAT'd IP address, or maybe the public

After version 8.3 and later

1. NAT is performed
2. The ACL is applied

* The ACL would use the real IP, or maybe the private IP.
