Oct 13 01:57:39 davetest22 ovpn-acme-server[7435]: WARNING: --topology net30 support for server configs with IPv4 pools will be removed in a future release. Please migrate to --topology subnet as soon as possible.
Will need to understand how this impacts clients and how to migrate before we turn this on
