Controlling FB4 through cellular router
Hi
First of all not to warry it is not for shows with audience.
I have a laser with FB4 and a cellular router in an agriculture field, and a laptop with Beyond and a cellular router in the control room.
How can Beyond recognize the FB4 over the internet?
Will VPN do the trick?
Did anyone controlled the FB4 over the internet?
I did it before with laptop next to the laser and controlled it using TeamViewer.
It worked well with one laser.
Now I need to control multiply laser and FB4's that are far from each other, so each laser will have it's own cellular router.
Any advice?
Thank you

Hi,
It's not easy. You can, but with a VPN working on layer 2 OSI (not the typical layer 3), so that UDP broadcast is also propagated for FB4 discovery.
Typically, Openvpn in TAP mode is working, but you need compatible routers on both end.
Of course, you need also a public IP on each remote location.
Finally, it's really NOT advised to do direct laser data streaming over carrier, not stable at all. Your best bet is to use Autoplay mode and you can eventually upload new shows remotely.

Thank you Sebastien
I only use the laser for one beam which I control manually from the control room, moving it left to right in real time.
I will try the things you suggested.

Does anyone know if the FB4 has a latency time-out feature?
In another thread, Archia mentioned that the FB4 was working when connected to the PC via a standard router and ethernet cabling, but when he tried using a "cellular router" (sic) it did not work.
Assuming that they are using a cellular modem to tunnel through the Internet from the control PC to the FB4, then I imagine this connection might have considerable latency compared with a local network setup. Just wondering if the FB4 might have some sort of built-in protection against excessive latency.?. (I honestly don't know.)

There is sort of timeout management for sure.
Recently I did test laser streaming through the cellular network via VPN, where there was bad network coverage.
Clearly I could see that for more complex frames, which needed more bandwidth, the laser output stopped after a short pause time. FB4 didn't continue to play forever the last received frame, it continuously monitors the stream and can detect when connection is lost.
