> 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.
