Configuring a Cisco ASA firewall

In this section, you will deploy a Cisco Adaptive Security Appliance (ASA) firewall on an enterprise network. You will gain hands-on experience in terms of implementing security levels on each interface, routing, Network Address Translation (NAT), and various IP services.

Before building the lab environment, the following factors are of importance:

• In the lab topology, use a Cisco ASA 5505 firewall, Cisco 2911 routers, and Cisco 2960 switches.
• Use straight-through cables to interconnect each device, as shown in the network diagram in Figure 15.18.

Please build the following network topology within Cisco Packet Tracer 7.3.1 for this lab exercise:

Once you have connected each device as shown in the preceding screenshot, we'll be using the following IPv4 addressing scheme to configure the IP addresses on each device:
