Network security group improvements—ICMP support and override default Azure platform considerations

Published date: July 29, 2019

New improvements have been added to network security group (NSG), which filters network traffic to and from various Azure resources. 

New NSG features: 

  • Specify ICMP as the protocol in your NSG rules, in addition to TCP, UDP, or Any. 
  • Override the default Azure platform considerations by creating an NSG rule with the following service tags. Please exercise caution when using these tags.   
    • ​​AzurePlatformDNS for DNS 
    • AzurePlatformIMDS for IMDS 
    • AzurePlatformLKM for Windows licensing (Key Management Service)
