I am running an Apache2 web server on a Debian 9 machine.
I have done a port-forwarding on port 80/TCP in my router, but regardless my website is not accessible from outside my LAN.
The response is simply "unable to connect". I did make sure that there's no firewall blocking it, netstat returns:
tcp6 0 0 :::80 :::* LISTEN 12899/apache2
Cheers for your time.
