Cisco ASA Series CLI Configuration Guide
Chapter 1 Getting Started
Factory Default Configurations
• Traffic flow—IPv4 and IPv6 traffic allowed from inside to outside (this behavior is implicit on the
ASA). Outside users are prevented from accessing the inside.
• DHCP server—Enabled for inside hosts, so a PC connecting to the inside interface receives an
address between 192.168.1.5 and 192.168.1.254. DNS, WINS, and domain information obtained
from the DHCP client on the outside interface is passed to the DHCP clients on the inside interface.
• Default route—Derived from DHCP.
• ASDM access—Inside hosts allowed.
