I would like to ensure my IoT devices, which are on their own subnet/VLAN go directly out to the Internet and cannot see devices on any of my other VLANs. Is it as simple as modifying the below rules that are now in place? The only things I want it to see is my DHCP server and my Pi-Hole, which is acting as my DNS filter. I also have a hairpin rule in place to prevent IoT devices from bypassing Pi-Hole.
