Description

In the course you will learn everything needed to install and configure a brand new Cisco ASA firewall with outbound internet access.

You will learn all commands needed to install the firewall.

  • Console access

  • Interface configurations

  • Access-list theory and how to apply them.

  • Restricting and providing management access.

  • Network Address Translation (NAT)

  • DHCP in the Cisco ASA
