> Key: CLOUDSTACK-9437

> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the

> Affects Versions: 4.6.2, 4.7.1, 4.8.0, 4.8.1

> 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.
