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)
