Azure NSG : SourceAddressPrefix range Error

Question

Hi,

Iam experiencing some troubles adding ranges of ip addresses on source and destination fields.

As far as i know Azure said that they accept address range :

Am i using it wrong ? Or this is just impossible to do with NSG ?

Thanks

Hello @Badr HOUSSNI ,

You can add ranges of IP addresses in classless inter-domain routing (CIDR) block notation (192.168.1.20/28, for example which will contain the IP range of 192.168.1.16 - 192.168.1.31) but not like you have mentioned in the screenshot. You can also use a comma-separated list of IP addresses.

Kindly let us know if the above helps or you need further assistance on this issue.
