The eight network interfaces of the ASA work only as Layer 2 ports, which is the difference of the from the other ASA models.

This means that you cannot configure a Layer 3 IP address directly on each interface. You can divide the eight physical ports into groups, called VLANs, that function as separate networks. This enables you to improve the security of your business because devices in different VLANs can only communicate with each other by passing the traffic through the firewall appliance where relevant security policies can be enforced.

All other switch ports are allocated by default to VLAN1. The default configuration of the Cisco ASA will be explained in the next section.

However there is a communication restriction between VLANs zones. Also, you cannot configure firewall failover redundancy with the Base License. These limitations are removed with the Security Plus license. To configure a DMZ VLAN on a Base License use the following commands: asa config interface Vlan 3 asa config-if no forward interface vlan 1 asa config-if nameif DMZ asa config-if security-level 50 asa config-if ip address Also there are no communication restrictions between VLANs.
