Note You use access rules to control network access in both routed and transparent firewall modes. In
transparent mode, you can use both access rules (for Layer 3 traffic) and EtherType rules (for Layer 2
traffic).
To access the ASA interface for management access, you do not also need an access rule allowing the
host IP address. You only need to configure management access according to Chapter 1, “Configuring
Management Access.
Information About Access Rules
You create an access rule by applying an extended or EtherType access list to an interface or globally for
all interfaces.You can use access rules in routed and transparent firewall mode to control IP traffic. An
access rule permits or denies traffic based on the protocol, a source and destination IP address or
network, and optionally the source and destination ports.
For transparent mode only, an EtherType rule controls network access for non-IP traffic. An EtherType
rule permits or denies traffic based on the EtherType.
