 When you create the gateway subnet, you specify the number of IP addresses that the subnet contains. The IP addresses in the gateway subnet are allocated to the gateway VMs and gateway services. Some configurations require more IP addresses than others. 
 
-When you're planning your gateway subnet size, refer to the documentation for the configuration that you're planning to create. For example, the ExpressRoute/VPN Gateway coexist configuration requires a larger gateway subnet than most other configurations. Additionally, you may want to make sure your gateway subnet contains enough IP addresses to accommodate possible future additional configurations. While you can create a gateway subnet as small as /29, we recommend that you create a gateway subnet of /27 or larger (/27, /26 etc.) if you have the available address space to do so. This will accommodate most configurations.

 The following Resource Manager PowerShell example shows a gateway subnet named GatewaySubnet. You can see the CIDR notation specifies a /27, which allows for enough IP addresses for most configurations that currently exist.
