I am using Devstack which is created using Liberty version.

I can be able to reach the outside world from the Instance which is created for demo project.

Demo project is using the private network.

But, Unfortunately instance which is created in a admin project is not working correctly as needed.

It is not reaching the outside IP.

Admin project is using the Public network.

IP of created Instances:

172.24.4.3 - Admin (Public)

10.0.0.3 - Demo (Private)

Please some one let me know your comments or suggestions.

Result of route -n from host machine:
