Access to Horizon drops after configuring br-ex port

Hello, I have been struggling understanding how the bridge works with OpenStack. I have installed Packstack but I have never succeeded to access outside the network. My Physical Network setup is rather challenging. I'm doing a Proof of Concept project for my school. I don't have access to school router nor I have permission to configure it. I have been given One IP ( to work with. While there are other IPs available on the network, I'm not allowed to use them because they are reserved for other projects. I have read a lot of documents but they all seem to be required that I give a range of IPs from my network.

I would like to know if is even possible to install PackStack in such condition. If yes, how?

The issue comes from the fact that every time I add my interface to ovs br-ex, I lose connection to my OpenStack Dashboard. (I do change the parameter of my enp0s interface and br-ex accordingly) My computer is running CentOS 7 and has one NIC which is connected to school network I'd appreciate any tips!

Configure as the Packstack host's IP address before installing Packstack. Also add --os-neutron-ovs-bridge-interfaces=br-ex:enp0s? to the packstack command. This connects the cloud to the school network and should enable your instances to get out to the internet.

Hello, Thank you for your reply. I did a fresh packstack installation with the IP with the commands you suggested. But the problem persists. I can't connect to the Horizon with that IP.
