ICMP protocol added in NSG rules

Sometimes it is the little things that makes you happy!

Somehow I missed the recent news on new NSG rule functionality. Nowadays it is possible to create NSG rules and select ICMP as separate protocol. This may seem a small thing, however it is actually great news.

When locking down your Azure Virtual Networks, it is recommended to start with a “Deny, any, any, any” rule and build up from there. However because previously you could not select ICMP as a seperate protocol, ICMP traffic such as ping was not working anymore after locking down.

With the option to select ICMP seperately as protocol, this problem has been solved now!

Azure Feedback started to work on ICMP support

A few days ago on azure.feedback.com the status was changed to started, however it is already available in the NSG rules. Documentation was updated 10 days ago.
