Recently I’ve had to configure a couple of firewalls for different clients, so I thought I’d write up some notes on putting a basic configuration in place.Cisco

The model I have been using is the ASA 5510, with Security Plus license. The Security Plus license converts ports 0 and 1 on the firewall to be gigabit ethernet – worth noting when you’re assigning roles to interfaces. It’s unlikely that your WAN connection will be anything close to gigabit speed, therefore configuring the WAN on ports 0 or 1 effectively ‘wastes’ this additional speed. The Security Plus license provides additonal benefits, but I won’t go into them here – you can find all the details on the Cisco website.

I’ve had to start with both a new unit, and a second hand one, so I’ll go through the process of resetting a used unit back to factory settings. For all of the following, I will assume that you have physical access to the unit, and are using the console for configuration via the command line. I’ve split the instructions up into a number of discreet posts based on different parts of the configuration process – links below:

As always, these instructions are written from my experience, and worked for me. You should test them in a lab environment to ensure that they work for you before trying them out on production equipment.
