Access docker internal network

[jarias]

Also if I use a tap device using virtio-tap instead of virtio-net It works fine but I don't want to do the dance of opening the tap device assigning an IP to it, then assign an IP to the eth0 device in the VM etc, etc.

[ailispaw]

It looks like an issue or behavior of vmnet.framework which xhyve uses for virtio-net.
It happens not only on boot2docker, but also rancheros-lite with xhyve.
I think you had better to open an issue at https://github.com/mist64/xhyve.
Thanks.

Thanks, I wish we can move tickets easily between projects 😄

Here is the xhyve ticket in case you want to track its progress

machyve/xhyve#42

@jarias Thanks for your understanding and using boot2docker-xhtve BTW.

I found something. vmnet uses pf. I gues that pfctl may be a tool to solve this isuue.

I check to see if there where any special rules vmnet creates but couldn't found any, I'll keep researching. Thanks for the info
