I want to revisit this topic because it seems that this feature should just work as the tablo device and the playing PC are on the same network. Also, the community has asked for a mean for remote discovery and access to their tablo device many years ago (2014 was the last post I saw) and it is still not supported yet today.
Tablo developers, please help us!
From my work, I started an openvpn session to my home and my work PC is on the same network as home (192.168.1.0). In fact I can ping the tablo device at 192.168.1.10 without issue.
I can also browse to the device at http://192.168.1.10 and it would display the message "Nuvyyo Tablo Server". However, when I try to discover and and sync it at http://my.tablotv.com, it always said that "No Tablo Was Found On Your Network". I have read other posts on the topic which suggested to change lower the route metric, etc. None has worked.
If it helps, I ran a port scan nmap on the tablo device and got the following:
$ nmap -Pn 192.168.1.10
Starting Nmap 7.12 ( https://nmap.org ) at 2017-01-17 13:14 Ame

If you have some idea on how to get my tablo device discovered and play, please share it with us.
I still think tablotv is a good core cutter service but I really hope that it could improve on some of the basic features like this one.
