Hi.

I have issue on my subscribed Azure VM running CentOS 8, where the iptables configured rule did not apply after the OS reboot. iptables-service package is installed, and "service iptables save" has been executed before rebooting the VM.

Seeking for advise..

Thank you.

    Hi.

    Notice the iptables still remain in-active after the VM reboot. The issue been resolved by enable the iptables service via "systemctl enable iptables".

    Thanks for your support and follow up.

    Regards..

    @kwyap

    Did you try disabling the firewalld (default service instead of iptables available now).

    Since you have installed the iptables, try to disable and mask the fiewalld service and check once. 

    systemctl disable firewalld  

systemctl mask firewalld

    Restart iptables service iptables restart

    Save service iptables save and reboot.

    You can also try to save the rules to the relevant file using iptables-save > /etc/sysconfig/iptables
