Restrict Pleroma to loopback interface
I recently noticed, that Pleroma is not restricted to localhost, but is listening on all network interfaces.
sudo ss -tln | grep :4000 LISTEN 0 128 0.0.0.0:4000 0.0.0.0:*
I guess there are currently many exposed port 4000 in the Fediverse.
If Pleroma is keeping the current behavior, then I would need to add a firewall configuration section to the installation guides.
