---------------------------------------

             Summary: Outbound traffic fails to work after VR is upgraded to post 4.6+ release
                 Key: CLOUDSTACK-9437
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9437
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.8.0, 4.7.1, 4.6.2, 4.8.1
            Reporter: Rohit Yadav
            Assignee: Rohit Yadav


When CloudStack is upgraded to 4.6+ version, due to changes in script. The default iptables
rules are saved at /etc/iptables/router_rules.{v4,v6} instead of the rules.{v4,v6} files.
The cloud-early-config file uses the rules.v4 and rules file, which are copied from iptables-{router,
etc.} templates.

When CloudStack was upgrade from 4.3 to 4.6+ version, and VR template upgraded to a 4.6 template
-- the rules.v4 file was copied from iptables-router template though the configure.py uses
router_rules.v4 file which does not have the FW_EGRESS_RULES chain declared. Because of this
the CsNetFilters fails to add the chain.

Workaround that works -- after upgrading the router, restarting the network (without cleanup
selected) fixes the issue.
