5.0.1". Rule with cluster interface in "Destination" should compile into matching ip addresses assigned to the cluster interface object and corresponding member firewall's interface object, but in v5.0.1 it only matched member interface address. This bug triggered when iptables version was set to 1.2.11 or greater. This was a regression from v5.0.0
