I’ll elaborate. I would make the Tablo IP address static in you router if you haven’t already done it for remote viewing. Then make the Tablo IP a static route on your windows device. Now see the post below.
My guess is that the app get’s it’s information from there. I could be wrong since I don’t know the discovery protocol. I would make a static route for the host api.tablotv.com that they mentioned above. I think that would convince the Tablo app to use the correct network.
