What is the difference between these ports sections in a egress in Network Police yaml?
I know is the dash, but what does exactly mean? :slightly_smiling_face:

 - ports:                  
    - port: 53                
      protocol: UDP
    - port: 53                
      protocol: TCP

and

  ports:                  
    - port: 53                
      protocol: UDP
    - port: 53                
      protocol: TCP

It’s the list @Edith Puclla so the first item in the list is indicated by - :wink: and so on for another new item in the list in this case you have a dictionnary(map) and the list into it

Edith Puclla:
@Sangeetha Radhakrishnan I know that it is a list, I mean if this restricts nod to ports or considers both.
