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 (172.28.230.33) 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 172.28.0.0/24. I'd appreciate any tips!

Configure 172.28.230.33 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 172.28.230.33 with the commands you suggested. But the problem persists. I can't connect to the Horizon with that IP.
