This is to create a MAC vlan on you synology to bridge interfaces

You will need to create the following folders from the main docker folder.

mkdir -p /volume1/docker/pihole mkdir -p /volume1/docker/pihole/pihole mkdir -p /volume1/docker/pihole/dnsmasq.d

My testing vlan uses 192.168.253.0/24

sudo docker network create -d macvlan -o parent=eth3 --subnet=192.168.253.0/24 --gateway=192.168.253.1 --ip-range=192.168.253.44/32 ph_network

If you are 7.1 DSM you will need to use this command

docker-compose -f /volume1/docker/pihole/compose.yaml up -d
