Hi abcdefgh, Tried reproing your issue over here. Looks like the issue is with tun module not being present inside the container. I guess the following would possibly resolve the issue (not tried though): Install build-essential, openvpn and makedev in the container Compile tun.ko as detailed here inside the container Do a modprobe tun Try connecting after that Alternatively starting the container with --network host works over here. Below are the steps followed: host # docker run --network host -t -i ubuntu:18.04 /bin/bash
container # apt-get install kmod iproute2 net-tools lsb-release ca-certificates sudo uml-utilities
container # dpkg -i pulse-version.deb
container # Execute the dependencies installation script
container # /usr/local/pulse/PulseClient_x86_64.sh ... After running the above command, the tun adapter is created on host machine host # ip addr
