hi all:� � �The network node(s) is the only node(s) that expose to the internet,so it's security setting is more important,So I think it needs to be protect by iptables or firewall etc.� � �On the other hand,network nodes control all the vm instances' network traffic,I have no ideas how to setting it's iptables rules.Is there any advices or examples to set the network node's iptables?
