Plex port forwarding on Google wifi
I just upgraded to Google Fiber and received a Google wifi device [A] as a router/wifi radio device.
Once I connected to the fiber jack with an ethernet cable, the wifi device comes online and is manageable on my phone with the Google Home app.
I connected my NAS device to the single ethernet port on the wifi device.
After a few seconds, the Google Home app displays the NAS and gives it a DHCP address.
Inside Google Home under the Wifi menu, I tapped on the Settings icon and selected “Advanced networking > Port Management”.
From there, I was able to add a manual forward for TCP traffic on port 32400.
I saved the setting and my Plex server was immediately able to connect with Remote Access.
