Comment 1 Thomas Woerner 2012-09-14 11:30:00 UTC
firewalld is the standard firewall solution with Fedora-18 and RHEL-7. Is the firewalld service active in your system? The firewall configuration is not complete. ssh is allowed in the default firewall zone, but the rules for this zone are not there and the network interface is not part of that zone.

Have you modified the firewalld configuration?

Comment 5 Thomas Woerner 2014-01-09 11:26:24 UTC
I can not verify this. It is working for me.

Closing as NOT A BUG.

Comment 6 Thomas Woerner 2014-01-09 11:50:28 UTC
Additionally firewalld is used as the default firewall solution in RHEL-7. The ip*tables services are not active, therefore you can not disable or stop them.

The firewalld bug mentioned above has already been fixed.
