The first thing you need to ask is: Why do you need IPv4?
I don't know much about your imaging servers: Do they accept incoming https connections, or is it some other kind of TCP or UDP protocol? Assuming it's https, why do you need to stick with IPv4?
> Hi, I’m helping a hospital in Buenos Aires that has lost their IPv4 due to their ISP moving to CGNAT, putting their on prem imaging servers offline for 7 days. (it’s ok for us though, we have a backup failover isp)
Two more things:
1: If you require IPv4, that needs to be part of the contract with your ISP. If they just arbitrarily turned you off, it means that you didn't contract for the services you thought you had.
2: IPv6 is supposed to solve a lot of these problems... So again, why can't you move to IPv6?
