Hello ,

I am new to Azure. I am trying to create NAT gateway under free subscription. region - East US2 . Under outbound IP, when
selected new public IP, I am unable to set CIDR /30 for public IP prefix ( for 4 addresses) , we are allowed to use 0-3 public addresess.

Do we have any solution for this? I need range of 0-4 . in any region if it is allowed?

    Thank-you, this confirms the quota has been reached. It looks like you are limited to 3 public IP addresses in this region and you have already used them all. The free subscriptions have a lot of limitations to them so you cannot create an IP prefix with 4 addresses.

    At what point do you get this error? Is it immediately when you select the prefix or upon deployment?

    Can you check your subscription quota - https://learn.microsoft.com/en-us/azure/networking/check-usage-against-limits

    I think on those trial subscriptions you get 10 public IP addresses so you may not have enough left in your quota for this prefix.

    Otherwise, can you share the exact error message with a screen shot?

    Thank you @Alan Kinane . I have shared screenshot. This is at time of creation NAT gateway. You can see error reflecting when selected IP prefix for (/30).
