Hello Herbert,

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

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

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