To be able to really use Metasploit in real world using laptops or own computer...one has to know "PORT FORWARDING" techniques... You need to look up for PORT FOWARDING from External IP : Port to LocalIP : Port.
here you are...Metasploit over different network and firewall (using dedicated hardware simulation)
Just that i dont destroy ESET NOD32....this time Windows Defender again! hehehehehe
