Problem: You need access to a machine on private network. The IP address to the machine is NOT public

Solution: If you have ssh access to a machine on the target network, use sshuttle to create proxy, allowing access to the rest of the network

1. Establish the ssh tunnel sshuttle -r <USER>:<PASSWORD>@<Host IP Address> <Allowable-Connections> -D
   1. -r – flag to input the hostname and user/password on the command line
   2. USER – user of the host machine
   3. PASSWORD – password to the host machine
   4. Host IP Address – IP address of the host proxy server
   5. Allowable-Connections – You can establish a range of IP addresses that will route through your ssh tunnel. Define this range using CIDR notation. By default, all connections are allowed (0/0)
   6. -D – flag to run sshuttle in a background process
2. The tunnel created is an open connection to the private network via an ssh connection to a server on the private network
3. Access a machine on the private network!
