Not able to access port (11444 & 5072) externally. Only working on Local Host not remotely. We are using Ubuntu on Google Compute Engine. Firewall rules Added
回答1:
As the netstat output shows, your services listening on port 11444 and 5072 are bound to localhost (127.0.0.1) which means they only accept connections on the local loop interface. Change the binding IP address on your service configuration to 0.0.0.0.

Just checking - have you also configured the firewall? By default, the ports may be blocked by the firewall. You can configure it to enable ports via either the Developer Console, or with the gcloud command line tool.
Some extra information about firewall's on Google Compute Engine can be found at: https://cloud.google.com/compute/docs/networking?hl=en#firewalls
