​To repeat Valdis' question:​

​And the router knows to send to the "front" address to reach the "back"
address, how, exactly? Seems like somebody should invent a way to
assign a
prefix to the front address that it can delegate to things behind it.

WG] I made reference to it in a previous message, but since the question
was repeated, I'll assume that was missed and repeat the answer. The
hypervisor folks seem to have figured this out so that it "just works"
without NAT, using virtual interfaces that have their own unique MAC
addresses so that they look like unique hosts to the network/DHCP server.
I'm using it on my FreeNAS (BSD) box at home with jails, and KVM supports
it, so chances are it wouldn't even be that hard to incorporate into
Android.

Thanks

​Hi Wes,

I saw your response, but creating a hypervisor-equivalent network stack
inside Android didn't seem particularly easy to me.  This may be, however,
because I've mostly dealt with OVS-style approaches in the past few years
and my calibration is off. If you have pointers to implementations that are
for mobile devices, I'd be happy to be educated.

regards,

Ted
