title: Azure NSG not working as expected
body: <p>I have an Azure external loadbalancer with a backend pool that contains 1 kubernetes master server and has a load balancing rule on port 443.</p>
  
  <p>I added a rule with priority 500 to deny all traffic coming from the internet on port 443 to the kubernetes master server. Works fine</p>
  
  <p>I added a rule with priority 400 to accept traffic coming from a certain public ip because I only want to be able to connect from that ip. I expected that I  should be able to connect but I can't.</p>
  
  <p>If I change the rule that accepts traffic from the source ip to internet then it works fine. 
  What am I missing?</p>
  
  <p>Kind Regards</p>
