Linux Firewall Configuration for Dermi Atlas Professional

On Linux, Dermi Atlas Manager makes no firewall change. The five Atlas ports are published by Docker Engine, which adds its own firewall rules for them. Docker's documentation on packet filtering and firewalls describes how these rules take precedence over front ends such as UFW:

• No UFW or iptables rule is needed to open the Atlas ports.
• A UFW rule does not close them either. The ports are reachable on every network the host computer is connected to, so access is limited at the network level, for example by keeping the host computer on the practice network only.

Atlas Manager itself accepts connections only from the host computer and never needs a rule.

Checking Access

1. Note the HTTP address shown on the Atlas Access card of the Atlas Status page.
2. Open that address in a browser on another device on the practice network.
3. The Atlas sign-in page opens.

If the page does not open, check that Atlas Access reads Network Access and that both devices are on the same network, then follow Troubleshooting Network and Connectivity Issues. The port list is in Firewall Configuration for Dermi Atlas Professional.
