The only problem with this is that on interface up/down it can take a few minutes for the network to be available. This may not be an issue with a server or idle desktop but may be confusing for non tech people or laptop users. If you can manage it, a pihole/pivpn instance may be better. Both of those can be installed on any debian distro easily.
