Configuring the Firewall

About UFW

UFW (Uncomplicated Firewall) is a user-friendly interface for iptables. It helps you:

• Block unwanted traffic
• Allow specific ports and services
• Whitelist IP addresses
• Log connection attempts

Default rules

When you set up the firewall:

• Default: Deny all incoming
• Allow: SSH (port 22)
• Allow: HTTP (port 80)
• Allow: HTTPS (port 443)

This keeps your server secure while allowing web traffic.

Adding rules

To add a firewall rule:

1. Go to Security > Firewall
2. Click "Add Rule"
3. Choose:
   • Action: Allow or Deny
   • Port: Port number or range
   • Protocol: TCP, UDP, or both
   • Source: Any or specific IP
4. Click "Add"

Managing rules

In the firewall interface:

• View all active rules
• Enable/disable individual rules
• Delete rules you no longer need
• Reorder rule priority
