#61521 Yes I've followed the Modem procedure for the Port forwarding and I've assigned the port 80 to the ESP.
Also the Internet provider confirmed me remotely that the port 80 is assigned to the ESP. Their question was if the port 80 is the correct one to assign for the ESP. Is there any other port that I can test?
