Assuming your Neutron and ML2 config is correct, it would be interesting to see how you created your external network. Start by sharing the details of external network and subnet.

Also tell us how you set up your cloud. Why a separate network node? Finally, what router type - DVR or centralized?

I am not clear about your setup. The tutorial you followed uses as external IP address range. Your instance has an internal address from that range.

Is your external physical network? Do you have a route to it? To what network is the instance connected?

By the way, the tutorial is for Icehouse, nine releases before the current Rocky. The config settings may not work with recent versions of OpenStack. At least it’s clear that your router is centralized, as this was the only option then.
