For running docker-ipv6nat on system starup, you can simply enable (and start) the systemd service: systemctl enable docker-ipv6nat.service systemctl start docker-ipv6nat.service. Also, MacVLAN needs to be used in projects where a common DHCP server is used, because the DHCP server would need a unique mac address which IPvlan does . docker network create -d macvlan --subnet=192.168.30./24 --gateway=192.168.30.254 -o parent=ens33 macvlan0 To use nftables to filter packets to the containers, you need to use table netdev and chain ingress.

For this reason, you will need to access Pi-hole using your Synology NAS's IP address and a defined port. So far, everything is working well. in ubuntu 20 you can manage firewall with ufw and you must add port 53 to firewall. # assign it an IP address; note the /32 subnet. Add a routing rule to route the Docker subset to the macvlan network so the host can see the containers: sudo ip link add macvlan link eth0 type macvlan mode bridge sudo ip addr add 192.168..101/24 dev macvlan sudo ip link set macvlan up sudo ip route add 192.168..200/29 dev macvlan.

The MACVLAN driver allows to create multiple virtual network devices on top of a single NIC, each of them identified by its own unique MAC address. Macvlan Bridge mode has a unique MAC address per container used to track MAC to port mappings by the Docker host. Select an IP in that range to allow host access. Here are the steps: Allocate an IP range for the network. You can use ipvlan instead, and get an L2 bridge.
