Hi @Gregory Wood ,
as long as there are Connected devices
in a subnet in an Azure Virtual Network you can't modify the subnet. No chance.
If I understand your scenario right:
You Azure Virtual Network: address space: 10.0.0.0/24
The subnet of the Virtual Network address space: 10.0.0.0/24
You want to add an additional subnet (for deployment of an Azure VPN Gateway)?
If so, you need to extend the Virtual Network
, for instance to 10.0.0.0/16
. This is possible if there are connected devices with the existing subnet which will not be modified.
If you extended the Virtual Network's address space to 10.0.0.0/16 you should be able to add an additional subnet, for instance with address space 10.0.1.0/24
, to the Virtual Network without any problem.
