Forwarding port 80 of WAN

I've ran below so I can access my GUI from the switch and WAN.  

configure
delete service ssh listen-address
delete service gui listen-address
commit
save
exit

I ultimately want to set up the following items: 

GUI from WAN [Remote] - WAN_IP:1234

GUI from LAN [Local] - SWITCH_IP:80 which would just be 192.168.1.1 which redirects to :443

Right now, I have a port forwarding rule to my web server on WAN:80 but it instead shows me the GUI.
