I launched an instance attached to the public net. When I ping it works. I attached another interface to this instance from the same network. The network topology shows that the instance has two links to the public net. Ifconfig in the instance shows both interfaces, the problem is only the first IP is pingable from outside What is missing Thanks for any help.

it's not an openstack problem, but routing problem.

look there: https://blog.ls-al.com/linux-routing-...

or there: https://access.redhat.com/solutions/3...

or probably you can try with network namespaces
