Think of sshuttle as a "poor man's VPN". You start
sudo sshuttle -r 22.214.171.124 0/0
and when you surf to
you're IP is 126.96.36.199, as if you were on a VPN.
But sshuttle takes a whole different approach via python. If it works, it is great to use with a rental VPS or sth. like that. It may not work on all Linux versions, but if it does, it is less hassle to run and set up than "softether VPN".
