1. Set up Google Compute Engine One-time configuration to create a suitable network for AppScale. You will be able to re-use this network for all AppScale deployments.
Go to your Google Cloud Platform project in the Google Developers Console. Under Compute/Compute Engine/Networks create a new network named “appscale” with the default Address Range (you can leave Gateway empty). For that network, add one new firewall rule with the following parameters: Name: “all-open” Source filter: “IP ranges” Source IP ranges: “0.0.0.0/0” Allowed protocols or ports: “tcp:1-65535;udp:1-65535”
