I have installed a Certbot certificate on my Lighttpd Raspberry server. Everything is working perfectly.
However I have a doubt. To make it work, I have opened ports 80 and 443 of my firewall, mapping Internet ports 80 and 443 to the same ports of the web server.
My question is very simple.
Is it safe to keep them open? It is not clear to me.
When I was on http without certificate, for safety I had a random Internet port (for instance 53636) mapped to web server 80 port.
Please clarify, thanks, Dan.
