go install github.com/n1nj4sec/pr0cks@latest

1. setup your iptable rules like in the example-iptables.sh with the range you want to redirect through the socks.
   You can for instance proxy throught a ssh server by using ssh -D 1080 user@pivotserver
2. start pr0cks :

pr0cks -socks5 127.0.0.1:1080

It will transparently redirect all TCP and DNS traffic matching your iptable rule to the socks server
