Are there any tools for automated building network diagram from ACL rules or any other firewall rules?

    Yes, there are. Redseal is one of them. Product recommendations are out of scope for this Stack. – gowenfawr Apr 21 '19 at 12:51

If you use Cisco it might be easier to build a network topology diagram using Cisco Discovery Protocol than firewall rules or ACLs even if manually done.
