Simulate traffic flow for troubleshooting

[sbirdsill]

Is there a tool or package for opnsense that will allow me to simulate traffic flow from source to destination, and tell me what is allowing or blocking traffic? (i.e. misconfigured firewall rules, NAT, etc.) Cisco's ASA and Firepower firewalls have a useful utility called packet-tracer that does this nicely. I am troubleshooting an issue where I am unable to block traffic from my DMZ to my LAN, despite configuring a firewall rule to block traffic from the DMZ net to the LAN net. Thanks.
