I currently have my LAN to WAN rule with ports and services set to Any. I'd like to limit that but I don't want to interrupt legitimate traffic out. Can you direct me to a guide or tell me how I figure which ports and services we're currently using?

You need to monitor the used ports in the connections log, and start listing the used ports numbers and create an entry for these ports/services if they are not already exist in the ports/services default list.

What I suggest is to create a new policy and place it above this "Any/Any" policy so it will be processed traffic first, and start adding the collected list of ports/services into this policy, and keep monitoring the used ports "in the connection logs" for both policies, until you reach to a point in which the "Any/Any" policy doesn't have traffic logs (later you can delete this policy)

For identifying the ports that are being used by certain specific applications and are not the well-known ports, you can setup packet capture on sonicwall and add them to the list of the allowed services.

For the scenario of tracing the TCP / UDP ports used by local devices / computers in your network, packet monitor feature in the SonicWall can provide greater help. Please follow below instructions to set the packet monitor on the SonicWall.

I followed Mahmoud's instructions but I'm still getting some traffic hitting the Any/Any policy. Is there a way on the packet monitor to filter it down by the priority 10 access rule so I can see what I'm missing? I've only found that I can see there's usage based on the traffic statistics in the Firewall - Access Rules page.

I think I have this figured out. It took a couple of your comments. First I used the connection manager as MABDELJAWAD suggested. That was pretty easy to look through. Then I created the rule above the Any-Any rule with those ports and, as NEVYADITHA suggested, turned on packet monitor on the Any-Any to see what was getting through. It was a lot. So then I had to look through that every so often to see what else needed to be added. I'm still doing that now.
