6. Create /mnt/data/nextdns and copy [nextdns.conf](https://github.com/boostchicken/udm-utilities/blob/master/nextdns/udm-files/nextdns.conf) to it.
7. Run the NextDNS docker container. Mounting dbus and running in privileged is only required for mDNS. Also, please change the --dns arguments to whatever was provided by NextDNS.
```
podman run -d --privileged --network dns --restart always \
