I've just spotted this in the Cisco ASA 8.3 release notes...
You can now configure access rules that are applied globally, as well as access rules that are applied to an interface. If the configuration specifies both a global access policy and interface-specific access policies, the interface-specific policies are evaluated before the global policy.
The following command was modified: access-group global
For users/companies which have migrated from Check Point to Cisco (usually to save on licensing fees), getting their head around a new interface level policy rather than a system (global) level is usually a bit of a challenge.
I'm looking forward to seeing if this really helps with policy migrations!
