macOS Firewall Configuration for Dermi Atlas Professional

On macOS, Dermi Atlas Manager makes no firewall change, and Dermi Atlas Professional needs no per-port rule. Devices on the practice network connect to Atlas through Docker Desktop, so the firewall settings that matter are Block all incoming connections and the entry for Docker.

Checking the Firewall

1. Open System Settings and go to Network => Firewall.
2. If the firewall is off, no change is needed.
3. If it is on, select Options and check two settings:
   • Block all incoming connections is turned off. While it is on, devices on the practice network cannot reach Atlas.
   • If Docker is in the list of applications, it is set to Allow incoming connections.
4. Select OK.

The Docker allowance can also be set from Terminal:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw --add /Applications/Docker.app
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --unblockapp /Applications/Docker.app

Checking Access

Atlas Manager itself accepts connections only from the host computer and never needs an allowance. To confirm the result, open the HTTP address shown on the Atlas Access card on another device on the practice network. The port list is in Firewall Configuration for Dermi Atlas Professional, and further checks are in Troubleshooting Network and Connectivity Issues.
