Does adding 127.0.0.1 make it so only that server can access it or what? I’ve seen that but not understand

127.0.0.0 is the localhost. This is the IP the container is listening on. Even if there was no firewall it wouldn’t allow any connection except from the host. If it’s set to 0.0.0.0 it means it’ll allow connections from any IP (which might not be an issue depending on your setup).

The reverse proxy runs on localhost anyway, so any other IPs have no reason to ever have access.

  Yes. 127.0.0.0 is the localhost. This is the IP the container is listening on. Even if there was no firewall it wouldn’t allow any connection except from the host. If it’s set to 0.0.0.0 it means it’ll allow connections from any IP (which might not be an issue depending on your setup).
  
  Thanks for explaining this!
