Nginx on IPFire LetsEncyrpt an open Ports on Firewall

I have installed Nginx on IPFire. Now i want to make certificate with “ --issue -d …”. That do not work because Port 80,443 are closed (i think).

How can i open Port 80,443 on the Firewall, NOT Portforwarding!! Open ON the firewall!

Thanks for help!

Never had any experience with this issue, so this is a guess (probably wrong). I would try both source and destination firewall/all and accept on TCP port 80 and 443
