Comparing ASA configs

Unanswered Question
Jul 5th, 2012

Hi All,

I am in the process of re-writing the configuration for an ASA using service groups and a new naming convention. Before implementing the new ACL I would like to ensure that it matches all the rules in the current ACL. Is anyone aware of software which can take two config files and compare them to ensure that they both match up and show any differences in ports allowed and/or IP addresses allowed.

if you use windows as your OS my favorites are the TotalCommander with the "compare by content" function or better

the small graphical open source tool Winmerge (

I found some software which does the job perfectly and would highly recommend!

I performed a full rewrite on one of our complex firewalls using service object groups and a new naming convention to make the rules easier to read but I wanted the services passing through the firewall to remain the same. The following software allowed me to compare two configurations and highlight any problems.
