> When we create a network with Egress rules set to default allow, the rules
> created in FW_OUTBOUND table should have a reference to FW_EGRESS_RULES chain
> which has a rule to accept NEW packets from the guest instances. Without that
> rule only RELATED , ESTABLISHED rule in FW_OUTBOUND chain will result in Drop
> of packets.
