Remote access Gen 4 Tablo between two subnets

I have two Gen 4 Tablos at two different houses. I am trying to set this up for remote access from the remote house (192.168.8.x subnet) to the main house (192.168.50.x subnet). This is primarily just to have the ability to check and schedule recordings from the remote location from time to time. I understand the bandwidth requirements for streaming and don’t expect streaming to necessarily work, although I have fiber with 300 Mbps upload at one location so it might work in one direction. Anyway, between my GL.iNet routers, I have WireGuard VPN setup, main Tablo is at fixed IP address of 192.168.50.18. VPN is working, from the remote house I can ping 192.168.50.18. From my Tablo app on my phone, at the remote house connected to wifi, I can access both Tablos - they both appear when I try to switch, and I can select each one and even stream through the VPN, although there’s occasional pauses, as expected, If I turn off the VPN, the one Tablo appears offline. So anyway, with the VPN on, things seem to work well with phone app.

Anyway, my problem is, if I try to switch Tablos from any of the TV’s (Fire TV and Roku), it does not show the Tablo at 192.168.50.18, it only shows the local Tablo as being available (at 192.168.8.246). I tried clearing cache, re-installing app on TV and Roku, and it made no difference. Why is it working with the phone app and not the TV… probably something to do with the different subnet addresses but I would have thought that if it works with the app, it would work with the TV’s. Any advice on what to try?

I use a TCP OpenVPN connection both-ways between two GL.iNet routers, and mobile devices can access the Tablo v4 on the other end just like your setup. I’m thinking it’s because the mobile client setup uses the account login process so it might be getting the Tablo IP address from the cloud.

And, like you are experiencing, my Fire TV device didn’t connect. I’m thinking that because it doesn’t do the same account login process as the mobile app(s), it is probably using a network broadcast to get a response from the Tablo on the network to obtain its local IP address in order to connect. So, when I enabled IGMP Snooping on both GL.iNet routers, the Fire TV was then able to connect to the Tablo on the other side of the VPN.

My Internet connections use the same commercial service provider on both ends with 450mbps downstream and 20mbps upstream. So it’s effectively just 20mbps and I’m able to stream from the Tablo just fine between the networks.

I think you are over complicating it with 2 Tablos. Why not just use 1 Tablo at 1 site and view it both locations? If you need more tuners get the 4 turner version.

Like @DaWeav said, i think it matters on which account the streaming device tablo app is logged into. I dont think the Tablo Streaming APPs scan across different subnets and vlans.

I think the easiest way to configure this is to create a SD-WAN between both sites. So this creates 1 big flat subnet instead of 2. So you can see both Tablos at the same time.

Thanks, that helps to a point. I enabled IGMP snooping and I can connect to the remote Tablo, but then the local Tablo does not appear on the local TV’s, but both still appear on the phone. Doesn’t make sense yet, I’ll look into this further, maybe I’ll learn something!

Oh yes as far as two vs. one Tablo - I already bought the 2 tuner version early on before the 4 tuner was available, and added the second tuner a couple years later when we got the second house (vacation house for us, AirBnb and other family). At the time the second house had very limited internet access, other than Starlink, which to me wasn’t worth the cost since we’re not always there, so we opted for the Tablo since local TV access would require little internet data. Also that is a couple hundred miles away, so there was a desire to get the local TV channels - another reason to have a separate Tablo. Also, now if internet goes down, there is still offline access, which wouldn’t be available if the second house had to rely on internet to access the main Tablo. So things are OK. Recently ATT upgraded a local tower and I got notification that ATT Internet Air was available, and it’s working good for me. Since things are much better for internet, it got me to thinking about remote access, as something just nice to have if possible.
