Firewall Bypass
The following nmap command is used to perform a fragmented packet scan on the specified target using Nmap in Kali Linux. When you run this command, Nmap will split its scanning packets into smaller fragments of 512 bytes or less and send them to the target system.

Command :
sudo nmap -f –mtu=512 <target>
