Implementing Cisco Network Security (IINS v3.0) (#20)

How does the transparent firewall process traffic through the ASA?

The firewall permits IPv6 and IPv4 traffic from higher security interfaces to lower security interfaces without an ACL.
The firewall permits Layer 3 traffic from lower security interfaces to higher security interfaces if a standard ACL is configured on the lower security interface.
The firewall permits broadcast and multicast traffic from higher security interfaces to lower security interfaces without an ACL.
The firewall requires ARPs to be inspected before they are allowed through the firewall.
