haugene/transmission-openvpn: Transmission not available after opening vpn connection

  • Hi all,


    I am new with OpenMediaVault and I am following the tutorials from Techno Dad Life.
    Now i was following the "How to Install Transmission with VPN on Openmediavault 2019" tutorial, but I have a issue and i can't find the solution.


    If I start the container and go directly to <ip omv>:9091, the Transmission GUI is showed.
    If i hit F5 the page reloads until the VPN connection is established, than i loose the connection with Transmission.
    I have tried many things with the network settings, but I cannot get it working.


    What do i wrong?


    Raspberry Pi 4
    Used OMV image: OMV_4_Raspberry_Pi_2_3_3Plus_4.img.xz (4.1.23-1 Arrakis)


    Docker Engine - Community
    Version: 19.03.2
    API version: 1.40


    First i create mynet network
    docker network create mynet


    After that i start the container, and when the VPN connection comes up the transmission webpage is not reachable anymore


    Even when I do it through the OMV GUI I have the same problems


    The container log file:


  • I found something out.
    If the container is running and the VPN connection is up i lose the connection.
    If i run a cmd in the docker container "ip r" i see all routes


    0.0.0.0/1 via 100.97.0.1 dev tun0 
    default via 172.17.0.1 dev eth0 
    37.252.248.92 via 172.17.0.1 dev eth0 
    100.97.0.0/16 dev tun0 proto kernel scope link src 100.97.0.32 
    128.0.0.0/1 via 100.97.0.1 dev tun0 
    172.17.0.0/16 dev eth0 proto kernel scope link src 172.17.0.3 
    192.168.1.0/24 via 172.17.0.1 dev eth0


    if i remove 128.0.0.0/1 via 100.97.0.1 dev tun0 by run ip route del 128.0.0.0/1 via 100.97.0.1 dev tun0 the web interface from Transmission comes back!


    If i check the traffic in the container it is still using the VPN connection.
    curl ifconfig.co returns the WAN IP of the VPN connection.
    If i run the same command on the Raspberry Pi I get my own WAN IP, everything looks good sofar.


    But how can i fix the issue without having remove the route manually?
