HelUfw Firewall Manager

HelUfw is an easy-to-use graphical interface for managing your Linux firewall using UFW (Uncomplicated Firewall). You can view status, add/remove rules, reset settings, and control logging.

1. Status Tab

1. The Status tab shows the current firewall status (Active/Inactive).
2. Click Refresh Status to update the status and rules.
3. Use Enable UFW to activate the firewall or Disable UFW to deactivate it.
4. The output area displays detailed UFW information and any command results.

2. Rules Tab

1. Add new rules using the "Add New Rule" section:
   • Select action: Allow or Deny.
   • Specify port or port range (e.g., 22, 80, 1024:65535).
   • Choose protocol: TCP, UDP, or leave empty for any.
   • Select direction: in or out, or leave empty for any.
   • Add an optional comment for reference.
   • Click Add Rule to apply it.
2. The "Existing Rules" section lists all current UFW rules.
3. Select a rule and click Delete Selected Rule to remove it.
4. Click Refresh Rules to update the list.

3. Settings Tab

1. Reset UFW: Resets all firewall rules to default. Use with caution, as this cannot be undone.
2. UFW Logging: Control the firewall logging level:
   • Enable Logging
   • Disable Logging
   • Low Logging Level

4. General Notes

• All actions that modify firewall rules require administrative privileges (you will be prompted for your password).
• Always refresh the status or rules list after making changes to see accurate information.
• Be careful when enabling, disabling, or resetting the firewall, as it can affect your system's network connections.

5. Troubleshooting

• If commands fail, ensure you enter the correct password and that pkexec is installed and configured.
• If rules are not applied correctly, refresh the rules list to check for updates.
• For unexpected errors, read the output area for detailed information.
