Allow firewalld for webmin access after post installation

FirewallD is an IPv6 compatible firewall mechanism used in recent Linux distributions (RedHat/Fedora/CentOS) replacing good old iptables.

  • dynamically managed firewall;
  • support for network/firewall zones (define trust level of network connections/interfaces;
  • support both IPv4 and IPv6;
  • support ethernet bridges and IP sets;
  • separated runtime/permanent configuration;
  • service/application can add firewall rules directly;
  • FirewallD with some basic rules
  • Firewalld should open port 10000 for webmin:

firewall-cmd –permanent –zone=public –add-port=10000/tcp

reload is needed to activate the permanent rule in current environment

firewall-cmd –reload

If you managed to stop firewalld restart with:

systemctl start firewalld
