Firewall Configuration (UFW / iptables)
Firewall Configuration (UFW) in the Panel
Manage open ports and firewall rules visually from the admin settings section.
Step-by-Step UI Guide:
- Log in as an administrator.
- Navigate to Firewall under the admin tools panel.
- To open a new port, click Add Firewall Rule.
- Enter the port number, protocol (TCP/UDP), and set action to **Allow**.
- Click Apply Rule. The panel updates UFW configurations dynamically.
Default open ports list: 8099 (Panel), 8080 (WebSockets), 80/443 (Web), 22 (SSH/SFTP), and standard email ports.
