I’m a months trying how to discovery it.
When a new incoming connection is getting established, router only sees destination IP address (and port). If many FQDNs resolve to the same (public) address, initially there’s no way for router to distinguish between different FQDNs. That part comes later, when initial TCP connection is established (and by that time router forwarded/NATed connection further on).
What you want to do is a task for some web service … could be that internet (through router) facing server only forwards (proxies) requests towards other servers.
