 Notice that when a rule with a nodeSelector applies to a Node, it only restricts the traffic to/from certain IPs of the Node.
 The IPs include:  
-1.The Node IP(the IP addresses of nodeInterface);  
-2.The Antrea gateway IP(the IP addresses of Antrea gatewayInterface);  
-3.The transport IP(the IP addresses of transportInterface);

+1. The Node IP (the IP address in the Node API object)
+2. The Antrea gateway IP (the IP address of the interface antrea-agent will create and use for Node-to-Pod communication)
+3. The transport IP (the IP address of the interface used for tunneling or routing the traffic across Nodes) if it's different from Node IP
+
 Traffic to/from other interfaces of the Node will be ignored.
 
 For example, the following rule applies to Pods with label `app=antrea-test-app` and will `Drop` egress traffic to
