I will check further or transparent proxying.

Can we not have Tor listen on 0.0.0.0:9050 even when transparent
proxying is enabled?  IIUC, a machine needs to have gateway configured
as FB machine (perhaps by getting DHCP config done by FB) for
transparent proxying to work.  I can see cases where this may be happen
always (FB is another participant in the network and not in-charge
because it has only one NIC).
