My notes on fiewall manager v2.
1) Good to see the rules and be able to edit them though the layout is basis and the capability is basic
2) We have a huge amount of errors against different Cisco ASAs where they have not been corrrectly setup with Firewall Manager or there are issues with the integration
3) It is very slow to add, update and edit rules
4) All in all, it's ok, but very limiting compared to having firewall access
