# Restart the '''iptables''' service
# Re-issue '''iptables -L''' commands making certain to redirect output to a second file ('''after.txt'''). This should provide a listing of the new state of your firewall settings.
# You now should have two text files representing the <u>before</u> and <u>after</u> states of your firewall.<br>Compare differences between these two files using the '''diff ''' command <br>(You should have used this tool in '''ULI101''').
#Run '''diff -u before.txt after.txt''' and figure out how to read the output.<br><br>'''TIP:''' You can also install a graphical tool that makes it much easier to see differences: '''kompare before.txt after.txt'''<br><br>
# You can use these tools to compare any two text files, they often come in handy. Note in your lab logbook the iptables rules that were added automatically by the '''libvirtd''' service.
