Describe the issue: 
When RHGS upgraded to latest build which is having firewall fix (adding firewall services to n/w zone), it will flush previous temporary run time firewall rules.

Suggestions for improvement: 
This one should know to admin before doing upgrade.

Additional information: 

while upgrading, it will reload the firewall so it's flushing all temporary firewall rules.
