I’m new here and asking myself, how i can use a reverse proxy to filter http commands to the apache 2 server (open HTTP Port). Cause of security concerns lets encrypt whants not to give their ip subnet to allow on the firewall rule only that subnet to access the http port on my server. So, which command should i only allow for the reneval process? And, is it possible to know, if the servers are only in north america? So i can make geo ip.
Thanks for any help. It is realy appreciated.
