Hi thank you for replying,
When you say it will function do you mean the Google home services or the Phillip hue?
The Phillip hue will, but I don't know if the Google home needs internet to get to the hue bridge.
Unfortunately I cannot put the entire network behind a pfsense box because putting the isp gateway into bypass so the wan can be forwarded disable my IPTV from working. If I put a rpi with pfsense as a bridge between my home network and my offline network (a wifi router and the bridge) could I restrict access that way without forwarding wan since that's what we're trying to block to begin with?
I guess the other question is, did the Google home service do a handshake with the bridge or is it a passive command. Does the Google home need to hear back from the bridge?
