XAMPP - my ip directs to router setup config instead of home server

I want to access my home server from the internet. I configured my router
to forward 192.168.8.3 my IPv4 address port 80 to 80. But when I attempt
to go to my IP address 43.xx.xxx.xx it redirect me to the router's setup
page, but when I type 192.168.8.3, it directs me right to my html.
The Apache config is allowing all.
Please comment me, so I can provide useful information.
