Creating a VNet, Servers and just a client VPN - how?

What I'm trying to do, setting up a Vnet in Azure and connecting a point to site vpn client , seems simple, but the Azure UI seems to disagree.

The org's local Network is 10.10.1.0/24. Their DG, fwiw, is 10.10.1.101, and the DNS server is 10.10.1.100. That all works fine. As part of VM provisioning, I will setup DNS records in the home DNS for the VMs created in Azure. I can manage that too!

What I want to do is to add a new subnet (10.10.2.0/24 in the cloud), and (for now) create a client (point to site) VPN for each machine needing access to the azure subnet being able.

I have a defined the Address space as 10.10.2.0/24, with two subnets:
skynet: 10.10.2.0/25 (where the hardware will go
Gateway: 10.10.2.128/28 for the gateway

SO far so good.

Now when I go to create the VPN connection, I am not sure how to configure it. What address space(s) is the connection looking for? I assumed this was the subnet to assign the client an IP address from (so chose 10.10.2.192/27 to bive me the needed client IPs. BUt that does not seem to work.

What do I configure for the VPN client?
