2 Creating an IP Network
To make your guest Compute Classic instances accessible over VPN, you should attach them and the Corente Services Gateway instance in the cloud to an IP network that you define in Compute Classic.
You can use an existing IP network or create a new one. For information about creating an IP network, see Creating an IP Network in Using Oracle Cloud Infrastructure Compute Classic. Note down the name of the IP network as you’ll need to provide this name later while creating the Corente Services Gateway on the Cloud.
