Hi, Your question is missing some details 1. What tenant does the network belong to? 2. Is it shared? If you want to use it for floating IP it shouldn't be shared. And VMs shouldn't be connected directly to it.

The new external network shared already, my confusion is why only demo account of external network can access instance, but admin account cannot, even I create anther user account with same of demo project. Anyone have been try RDO caused this problem ?
