#plan9 updates! some nice progress today:

Hooked up my laptop to the closed network via wired connection (which has its stack in /net), then connected its wireless interface to the home network (placing the stack in /net.alt)

Then my dhcp server inside the closed network can remotely mount /net.alt from the laptop, bind it over its own /net in one window (thus making it the default network stack for that namespace), and use it to access the home network from inside the closed network, via the laptop

I also found out why my dns wasnt working properly, but didnt get around to fixing it yet
