Understanding the Network Access Rule Hierarchy
The rule hierarchy has two basic concepts:
■
Specific rules override general rules.
■
Equally specific Deny rules override Allow rules.
When evaluating rules, the Internet Firewall uses the
following criteria:
■
A rule defining a specific service is more specific than
the default rule.
■
A defined Ethernet link, such as
LAN, WAN, or DMZ, is
more specific than
*
(all).
