LAN traffic getting blocked by WAN "Block Private IPs" Rule
«

I recently got a Qotom box, and it's been nothing but headaches. I installed Opnsense 3 times this weekend. This last time, my internal LAN traffic outside the ISC DHCP range was blocked by a WAN traffic rule.
I used to have my pi-hole handle the DHCP, but this was causing some general weirdness.
This box has 4 10G SFP ports and 5 2.5G ethernet ports. I've bridged all but one of the ports together, leaving the last one for the WAN port.
My LAN is a wide subnet - 192.168.0.0/20.
Gateway (OPNSENSE) - 192.168.0.1
DHCP Range - 192.168.12.10 - 192.168.12.254
Various Proxmox servers in a cluster are on 192.168.10.xx/20, and I can't communicate with them.

I would strongly suggest purchasing a switch. Other than that, perhaps start your troubleshooting at Step Six:

THANK YOU!
I missed those steps during the last reinstallation.
I plan on getting a proper switch, but this has to do for now.
