I have two WAN connection. The first WAN connection connects via FTTH modem. The second connection connects via 4G LTE CPE modem. I have configured fallback and load balanced dual WAN connection on my pfSense box. However, once in while the Internet connection either one of the WAN goes down. How can I tell pfSense to send an email notification when fallback (or any) WAN connection goes down? How to configure pfSense email notification when an alert happens?
