# Firewall

View and edit firewall rules.

OpenPanel supports both ConfigServer Firewall (CSF) and Uncomplicated Firewall (UFW). By default, CSF is installed, but you can choose to install UFW instead by [using the `--ufw` option during installation](/install).

Based on the installed firewall, the **OpenAdmin > Firewall** page will display either the ConfigServer Firewall UI or the custom UFW interface.


## CSF

If ConfigServer Security & Firewall (CSF) is installed, it's integrated UI will be displayed on **OpenAdmin > Firewall**.

For instructions on how to use the CSF UI, please refer to [ConfigServer Security & Firewall official documentation](https://download.configserver.com/csf/readme.txt).

## UFW

If Uncomplicated Firewall (UFW) is installed, our custom interface will be displayed on **OpenAdmin > Firewall**.

The firewall settings page provides three tabs:

- IPv4 - that lists all IPv4 firewall rules
- IPv6 - that lists all IPv6 firewall rules
- Logs - displays the UFW service log

### View existing rules

The table shows firewall rules, showcasing information such as rule ID, action, ports, source/destination IP, and the username of the user utilizing the port.
For IPv6 rules, navigate to the IPv6 tab.

## External Firewall

Some cloud providers, like [Hetzner](https://docs.hetzner.com/robot/dedicated-server/firewall/), 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.

## Restart rules

To re-open all necessary ports for OpenPanel services and users, run the command: `opencli firewall-reset`
