If you need to share your cloaked connection from your OSX laptop then you can use native OSX feature. 

If you want to share IDC VPN via Wi-FI then connect your Max OS to your router via Ethernet, but if you want to share you VPN connection via Ethernet (use twisted UTP cable) then you have to connect your Mac OS via Wi-FI .

So you need to create a VPN connection. More info here.

And you can share it at "System Preferences->Sharing"

Click on Internet Sharing option and select your L2TP VPN as "Share your connection from"  to WiFi or ethernet. Now you can enable the "Internet Sharing" checkbox and confirm the alert.

And then use UTP cable or Wifi to interconnect MAC and other devices.
