List the private IP address of a virtual network gateway
Show the private IP address of a virtual network gateway in the "Connected devices" blade.
Currently, the gateway private IP addresses are not required for configurations or operations, other than the GatewaySubnet range. They should have been hidden from users. The gateway resource model does not have a field for those either.
There may be use cases for new features down the road. We will update the gateway resource model accordingly and expose those properly.

The Private IP Address is needed for an on-premise RADIUS configuration. The VPN Gateway RADIUS side of the configuration requires the on-premise IP Address of the RADIUS server and the Shared Secret. The on-premise RADIUS Server requires the private IP Address of the Azure side (VPN Gateway) and the Shared Secret. There does not seem to be anywhere to obtain this address.

The private IP Address is actually needed and should be displayed. Imagine you're doing VNET Peering with Transit Connectivity between spokes and instead of using a virtual network appliance for your UDRs, you're using your Virtual Network Gateway. When creating your UDRs, you'll want to see the virtual network appliance IP Address.
Taking offline with Farouk to further clarify.
Agreed this is not about configurations or operations but just about avoiding some confusion.
Customer always ask about this "reachable" IP (.245) but we do not have any official statement about what it is related to.
