In our current setup we have an IP address assigned with the first available IP from a given allocation pool.
How can we change our config files and run deploy again, so it would change existing nodes to have cerrect settings and have it there after redeployment?
The reason is that we have our switches not managed by cloud and it can flush ARP only after 5 min (smallest value) so ALL VMs that are spawned earlier than 5 min cannot be reached from outside. Also, our instances lifetime is around 2-3 min and the next instances spawn in a minute after the previous one was deleted wouldn't be accessible due to that.
