I am working on a website at the moment which will allow users to top up their electricity via the website a replication of what is in place but we are now changing the site to be hosted on azure. As part of this process we require a VPN connection to be made with a 3rd party who own the metering equipment so that we can retrieve the vend codes at time of purchase.
How can I create this VPN? I have tried setting up a VPN but I am unsure as to how this will affect my existing network configuration and I am unsure as to the address spaces and vpn ip addresses to be used. Where does my azure website come into the connection?
