    iptables or selinux?
    iptables: "chkconfig ipchains off" and "chkconfig iptables off"
    for selinux "setenforce 0"
    first check "sestatus | grep -i mode" if Current mode: enforcing

    works for RHEL dunno for coreOS

    iptables
    already tried
    service stop iptables
    service disable iptables
    and
    systemctl stop iptables
    systemctl disable iptables

    which lead to
    Failed to stop iptables.service: Unit iptables.service not loaded.
    and no output which led to that it was still enabled after an reboot

    dont mind in a normal network it would be so to be better to not turn off a firewall but it always depends on the network you are working on

    Firewal was there for reason. Try other distros if you want firewall free

    And never try Core OS. Ubuntu and x86 Android Noob here

    Are you sure you have a firewall enabled in the first place?

    CoreOS is made to be used as a container, thus it is lacking a lot of tools that often come bundled with consumer versions of Linux. I know that past versions of CoreOS came with no firewall rules. I haven't played around with it for the last year or so, so that may have changed.

    This may be of use to you: https://www.jimmycuadra.com/posts/securing-coreos-with-iptables/

    It explains how to use cloud-config with iptables.

    I'm not using coreos, but to see if iptables service actually running or not, try
    systemctl status iptables.service

    to stop;
    systemctl stop iptables.service
    but this is not permanent and will restart after reboot

    systemctl disable iptables.service
    should work, but not tested. good luck googling.
