### Customization
* Feel free to change [20-dns.conflist](../cni-plugins/20-dns.conflist) to change the IP address of the container.
* Update [10-dns.sh](../dns-common/on_boot.d/10-dns.sh) with your own values
* If you want IPv6 support use [20-dnsipv6.conflist](../cni-plugins/20-dnsipv6.conflist) and [10-dnsipv6.sh](../dns-common/on_boot.d/10-dnsipv6.sh). Also, please provide IPv6 servers to podman using --dns arguments.

### Steps
1. On your controller, make a Corporate network with no DHCP server and give it a VLAN. For this example we are using VLAN 5.
2. Install the CNI plugins with by executing [install-cni-plugins.sh](../cni-plugins/install-cni-plugins.sh) on your UDM
3. Copy [20-dns.conflist](../cni-plugins/20-dns.conflist) to /mnt/data/podman/cni. This will create your podman macvlan network
4. Copy [10-dns.sh](../dns-common/on_boot.d/10-dns.sh) to /mnt/data/on_boot.d and update its values to reflect your environment
5. Execute /mnt/data/on_boot.d/10-dns.sh
6. Run the AdguardHome docker container, be sure to make the directories for your persistent AdguardHome configuration. They are mounted as volumes in the command below.

* The NextDNS docker image is not supported by NextDNS. It is built out of this repo. If you make any enhancements please contribute back via a Pull Request.
