Chrome Version       : 
Version 56.0.2924.110 (64-bit)
Platform 9000.91.0 (Official Build) stable-channel cyan
ARC Version 3756504
Firmware Google_Cyan.7287.57.100

What steps will reproduce the problem?
(1) Download bubble upnp/dlna server from play store under chrome-os
(2) Run dlna client like vlc (go to network tab) and it will see the bubble server
(3) On another client on the same network as the chrome-os/book you will not see the bubble server

What is the expected result?
Clients on the same network will be able to see server resources running in ARC just like on a normal android devices provide.

What happens instead?
Network access is restricted/unavailable for server apps.


Theory:
The ARC/Android subsystem is running via a bridged network interface with a private (and NAT'd) subnet that cannot be reached from other machines on the chrome-os network.
