setting up alert when public ip access to internal server via NAT

[koko_adams]

Does anyone know of a way to set up an alert such that when a IP is connect to some internal server via NAT , and can be sent notifing me of said event?

When anyone accesses the server externally?

Not directly in pfSense but you could make sure the firewall rule passing traffic to that NAT has a suitable description and has logging enabled. Then export those logs via syslog to something that can trigger on such a log event.

That is a good way to spam the shit out of yourself ;)

Yup, probably. Unless that rule has a restricted source.
