It must be a port alias or integer between 1 and 65535": The selections made under NAT/Port Forward/Edit; the rest left at pfsense default Interface: WAN Protocol: TCP Destination: WAN Destination port range: 443 Redirect target IP: 192.168.2.100 Strange, your are omitting the "Redirect target port" field. It should be Redirect target port : 443 en then pfSense will accept your NAT rules : [image: 1534259823312-dfbacfd7-24b6-425f-a5c5-dfa51fc730d1-image-resized.png] Gertjan Thanks so much.
