How to share Internet from Android via Ethernet The Situation: I've got Android running on my Cubietruck. Now I want to share the existing Internet Connection (Wifi) with my Win8 Desktop PC over Ethernet, so the stream would be

Internet –wifi→ Cubie –ethernet→ PC

I just found a thousend tutorials about making this the other way round. Is there any way to make this possible?
I'd suggest using iptables. You can find more about theme here - definitely take a look into simple usage example. https://help.ubuntu.com/community/Internet/ConnectionSharing

The only one problem is that iptables binary isn't really built-in into Android.
But hey, they came up with solution already http://forum.xda-developers.com/showthread.php?t=444004

So you can even use the example from Ubuntu help now!
