+- **`alert=on`**
+ 
+   - ICMP Alert: It blocks outgoing ICMP and UDP packets with specific destination ports (33434 and 33534) for a minute and then restores the original firewall rules.
+   - Port Alert: It drops incoming TCP packets with the SYN flag set for a minute and then restores the original firewall rules.
+
+- **`alert=off`**
+
+   - If alert is set to off, the script does nothing ( : represents a null command in bash ). No alerts are set up.
+
+To summarize, ICMP and Port alerts when alert=on by using the icmp_alert() and port_alert() functions, respectively. It saves the current firewall rules to a backup file and runs the alert functions in the background, storing their respective PIDs in temporary files. If alert=off, the script does nothing related to alerts.
