Hello Herbert,

assuming VPN-Server side an router act as authoritative nameserver you may try this:

	name: "myvpn.org."
	stub-addr: <ip-address of your DNS on the VPN server side>
	name: "lan."
	stub-addr: <local router's ip address>
	name: "."
	forward-addr: <ip address of your ISP's resolver>

You may replace a stub-zones with a forward-zones
