I am so perplexed. My OPNSense logs show a bunch of traffic originating from LAN to the Internet blocked by the firewall's 'Default deny rule'. But the vast majority of the traffic flows just fine. I spent hours on the firewall rules trying to make sense of it. No explanation.
The only reasonable explanation I have, which is what I want to validate here, is that when Sensei decides to block something, it invokes this firewall rule to do it. Is that the case?
