Description

This is the test case to check if runtime changes of firewall zones are usable.

Settings in the zone done with firewall-cmd (without --permanent switch) are only valid till reboot or firewalld service restart.

How to test

Get settings of work zone

 firewall-cmd --zone=work --list-all

Enable service samba-client in zone work

 firewall-cmd --zone=work --add-service=samba-client

To check (as root) if it has been enabled:

 iptables-save | grep work

These two lines should be in the output:

 -A IN_ZONE_work_allow -p udp -m udp --dport 137 -j ACCEPT
 -A IN_ZONE_work_allow -p udp -m udp --dport 138 -j ACCEPT

And

 firewall-cmd --zone=work --list-services

should contain samba-client.

Now undo the previous change. You can either manually remove the service

 firewall-cmd --zone=work --remove-service=samba-client

or just restart firewalld,

 service firewalld restart

because the change we did has not been permanent.

 firewall-cmd --zone=work --list-all

should now show the same output as for the first time, i.e. no samba-client.
