Port Forwarding

Simple port forwarding tricks

Main Concept: Accept traffic on a given IP and then redirect to another IP, PORT


A windows box wants to connect to an external device using RDP but due to the firewall restrictions it cannot.

We can set up a proxy on Linux box to bypass this:

vi /etc/rinetd.conf
(ADD) bindaddress                               bindport   connectaddress                   connectport
      local/public IP on kali (   80         External IP we want to connect   3389
/etc/init.d/rinetd restart
# Connect from windows to the external IP using RDP with

Investigate sockets running on the target

ss -tulpn

-t:	Display TCP sockets
-u:	Display UDP sockets
-l:	Displays only listening sockets
-p:	Shows the process using the socket
-n:	Doesn't resolve service names


### On Windows Target ###

### On Kali ###
./chisel_linux server --reverse --port 9002
