Site to Site VPN Connection

Hi, 

I am trying to create a Site to Site VPN connection between Azure and on premise network.

As part of VPN creation we would need information for the following couple of things :

1. Virtual Network details (Network address and Subnet)

2. Gateway Details (Network Address, Starting IP address , Subnet etc.)

I tried using the information in the following screenshot but it failed to create gateway.

Please suggests what should be the IP addresses ?

Thanks,

Prav
