With "stock" I mean default Android VPN service.
It it possible to use TAP on Android but there is some (expert) work to do. It is not easy, at least I've tried several times on my SGSII with CM11 without success. The default on Android (and recommended for remote access) is TUN. With TAP routing is easier but it generates more traffic as it is a layer 2 protocol and all broadcast messages (such as ARP) will flow throug VPN.
Here in XDA you can find some info about configuring TAP. But there is not much threads because it is recommended to use TUN.
I'm using a NetGear WNR3500Lv2 router with TOMATO firmware, what is far better than NetGear firmware. You can try it. Search "Tomato by Shibby" on Google to see if you router is supported.

The open vpn on the nighthawk is TAP based, android only supports TUN. This is the whole purpose of my post. Perhaps i should have made that more clear. Any nighthawk owners want to chime in?
