When I set external IP to None in the network interface of GCE instance the configured startup script is detected but it doesn’t run. The startup script runs when I update the VM and set an external IP. I didn’t find any documentation regarding this.
All the VM instances are part of an instance group which is the backend of an internal load balancer, so I don’t need an external IP on them.
Hi @pragyandas ,
Can you please share with us your startup script and give more details about what do you want to achieve?
I am just trying to install a list of binaries from the internet
It seems that you don’t have a Cloud NAT provisioned, without this none of the servers from a private network will be able to connect to internet and pull the packages.
If you don’t have that just go ahead and create a Cloud Router + Cloud NAT, attach that your private network and you should be good to go.

This solved the issue – thank you very much!
I wish this was part of the VM metadata configuration 
Glad to hear that worked
