Hello,
I am new to using firewalld. I have been through the documentation at
https://fedoraproject.org/wiki/FirewallD, but am having some trouble with configuration.
It would seem that, regardless of zone or services enabled, I cannot ssh into the machine
that has firewalld running without adding the client's subnet to the trusted zone. In
addition, adding "UseDNS no" to the end of /etc/ssh/sshd_config seems to ignore
firewall configuration.
I have been using firewall-cmd in order to set firewall options, if it makes a
difference.
It seems that there is no HOWTO for getting started with firewalld, and there doesn't
seem to be any one resource that's helpful for troubleshooting problems such as this.
Thank You,
David Fryer
