Firewall

OpenPanel supports ConfigServer Security and Firewall (CSF).

CSF

Firewall (CSF) UI is displayed on OpenAdmin > Firewall.

For instructions on how to use the CSF UI, please refer to ConfigServer Security & Firewall official documentation.

csf firewall

If you need to re-open all necessary ports for OpenPanel services and users, run the command: opencli firewall-reset.

External Firewall

Some cloud providers, like Hetzner, offer their own external firewalls. If you are using an external firewall, ensure the following ports are open for OpenPanel services to be accessible: 53 80 443 2083 2087 32768:60999

If you are using a custom port for OpenPanel instead of the default 2083, ensure that port is open as well.
