Hi,
I guess in general the ASDM view is as close to you can get to visualizing the firewall rules and configurations.
I am not the best person to talk about ASDM as I build all rules through the CLI of the ASA.
The ASDM does have an option atleast to view a single rules in a Diagram which clarifies in what direction the rules is controlling traffic etc
Heres an very simple example from my home ASA
First when accessing the ASDM you go to Configuration -> Firewall -> Access Rules
Click on the pictures to view them full size
At the top bar you will notice a button called Diagram
This will enable the ASDM to show a small diagram related to the interfaces, direction, action, networks/IPs and services configured in the rule you have currently chosen by left clicking the rule with mouse.
For example I have an "permit ip any any" rule
After selecting the above rule I will notice that since I have selected Diagram in the above bar that the bottom portion of the ASDM shows a Diagram related to this rule.
As you can see it shows the following things
- The rule (and the ACL in which the rule is located) is controlling traffic "inbound" to the interface called "LAN"
- The service allowed is "ip"
- The action is "permit"
- The source and destination network in this case is "any"
I dont know if this is of any help but its the only thing I can think of related to the ASA itself as a way to visualize the ACL rules.
Hope this helps
