Cisco ASA5500 Setup

Cisco ASA5500 Setup

In my test enviroment i have a ASA5510 with a Basic Configuration. You can use this as a starting point for configuring the ASA5500 Series Firewalls.

The ASA5510 is connected behind the Outside ASA5500 Firewall, this ASA will do the Packet filtering,
because i am a friend of KISS (“keep it simple and straightforward”), things get complicated by it self.
For the same reasons i like diving after the DIR (“Do it right”) Method.

In this post we will begin with a basic Setup of the ASA firewall. In the next posts i will describe other topics based on this setup.
