Shiva, iptables changes are made by neutron and a variety of other services and those should not be modified by hand. They will be re-created when certain actions are triggered in OpenStack. If you are trying to change the iptables rules for a launched instance that should be done with security groups and not by direct manipulation of the iptables rules. Maybe you could describe that it is you are trying to do and we can provide guidance? --- Joseph Breu Deployment Engineer Rackspace Private Cloud 210-312-3508 On Mar 28, 2014, at 3:10 PM, shiva m <anjaneya2 at gmail.com> wrote: > Hi Razique, > > Thank you for your reply.
