Can't add IP address to storage account
I can no longer add an IP address to a storage account networking using the portal. This started within the last week. I get the message "Invalid argument: 'The prefix must be between 0 and 30.'."...
Please are you adding Internal IP or External IP range in firewall address?
Seshadrrmy own single external IP address. The IP address is a valid external IP address.
When adding it in the Networking > Firewall for the storage account I receive the following error message.
The IP address is a single, valid external IPV4 address.
- Try to use with CIDR notation with a small range, Usually, when you access the storage explorer on your own browser it will automatically pick up the client IP address where you can add with a single range, however for the definite manual range try to use CIDR notation. I have been tested with the same IP which i have received from ISP with CIDR which results in the success
- A small CIDR range is unacceptable as /30 results in 4 IP addresses having access.
Picking up my own client IP is fine, but this doesn't work when I need to add other single IP addresses for those without access to the Azure portal.- Yes, through Portal the argument error in which is accepting from o to 30 CIDR, whereas by CLI it accepts with your own IP
az storage account network-rule add --resource-group "myresourcegroup" --account-name "mystorageaccount" --ip-address "16.17.18.19"
- CIDR notation using /31 and /32 will not work.
- I tested with CIDR /30 which has a minimum host address which works for me.
It also did used to allowing single IP addresses, as I have many storage accounts, each with a couple of single external IPV4 IP addresses in the firewall.
- I need to add a single IP address. I've tried 71.59.0.15, 71.59.0.12/32 and get the same error. The field validation should allow individual IP addresses or CIDR prefixes between 0 and 32.
