Description of problem: when i try to apply the modifications an error window open with this message : 
org.freedesktop.DBus.Python.OSError: Traceback (most recent call last):

    os.utime(dst, (st.st_atime, st.st_mtime))
OSError: [Errno 13] Permission denied: '/etc/sysconfig/ip6tables-config.old'

At the same time i receive a selinux alert : 
SELinux is preventing /usr/bin/python from setattr access on the fichier /etc/sysconfig/ip6tables-config.old.

*****  Plugin restorecon (94.8 confiance) suggéré*****************************

Siyou want to fix the label. 
/etc/sysconfig/ip6tables-config.old default label should be system_conf_t.
Alorsyou can run restorecon.
Faire
# /sbin/restorecon -v /etc/sysconfig/ip6tables-config.old

*****  Plugin catchall_labels (5.21 confiance) suggéré************************

Sivous souhaitez autoriser python à accéder à setattr sur ip6tables-config.old file
Alorsyou need to change the label on /etc/sysconfig/ip6tables-config.old
Faire
# semanage fcontext -a -t FILE_TYPE '/etc/sysconfig/ip6tables-config.old'
where FILE_TYPE is one of the following: system_conf_t, firewallgui_tmp_t. 
Then execute: 
restorecon -v '/etc/sysconfig/ip6tables-config.old'


*****  Plugin catchall (1.44 confiance) suggéré*******************************

Siyou believe that python should be allowed setattr access on the ip6tables-config.old file by default.
Alorsyou should report this as a bug.
You can generate a local policy module to allow this access.
Faire
allow this access for now by executing:
# grep system-config-f /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

#============= firewallgui_t ==============
allow firewallgui_t etc_t:file setattr;

audit2allow -R

#============= firewallgui_t ==============
allow firewallgui_t etc_t:file setattr;

and the modifications are not applied when i try to verify by running 
iptables -L -n
