docker0 zone not applied in firewalld, relates to NetworkManager

asked 2017-01-20 18:10:25 -0500


I am starting to use docker on a fedora server which is running for several years (installed at ~18, now at 25). Some of the services are not yet available as docker container, they are still normal services on the host like a database, mail, etc.

I can't change the zone of docker0 to trusted. FirewallD just doesn't do it and all my containers are not able to connect to the host (for example to the database, managesieve).

Related to but those solutions just don't work. Need help desperately.
