OpenVPN on DietPi (as DNS) and separate OMV Sever: can't connect to OMV :(

  • Hi there,

    I have some troubles setting up my Openvpn on a DietPie (running as DNS / PiHole) and a seperate OMV NAS.
    I'm trying to get the connection to the NAS (webGUI + SMB) via OpenVPN (except there's a better way?)
    What I still got working is acess to Internet via VPN and I can connect to Router (running on und DietPi (

    What I've done so far:

    1. Setting up Router with
    - as DNS-server
    - portfowarding of udp 1194 on
    - a route from to

    2. Running OpenVPN on Dietpi with this config (comes from PiVPN):

    Router is defined as DNS in server.conf, but forwards to DietPi / PiHole on

    3. Iptables on OMV machine:

    If you have any ideas how to solve my problem, please let me know....

    Viele Grüße
