LAN and WIFI Bridged or not?

Yes, they are bridged. I can see my router, which is wired to the TM modem LAN port, from a TM connected wireless devices. Being on the same subnet, the wireless and LAN ports would be bridged. It's still possible to isolate bridged ports to prevent them from talking to each other. But for my TM device, that does not appear to be the case.

I''m still concerned about what, if any, firewall functions are turned on in TM's Home Internet device. As such, I won't be connecting directly to its wireless network until that information is published. Until then, it would be nice to just turn it off.
