I do not think my network is engineered at all, and it is certanly not over engineered I am not sure what gave you that impression.
I can list for you how my setup looks like:
I have a a simple Mode-S Beast receiver (ethernet) located in a mountainhut connected to a friends basic 4G router from our local internet company.
Conveniently a 4G antenna from the same internet company is located on the same mountaintop. So the 4G internet connection is solid.
We can access the router it remotly and open ports and change some basic settings if we need.
On my end I also have an basic home router connected to a 100MB/S Fiber connection. The server is an old PC running windows 7, VRS and nothing else.
There is nothing more to it, Just couple of routers and couple of lan cables, plug and play
But regarding my problem, This setup is almost indentical to all the other receivers I have access to (Mode-S Beast on a basic router)
Andrew's suggestion did not work and I an not requesting more for him, I am really thankfull to his contribution.
I have tested the feed with Planeplotter and I have no cutoffs there.
There is one workaround that I can think off, but that would deffinetly be considured over engeneering in both of our books

that would be using a PP setup to forward a stable feed to VRS
But for now I just reconnect the feed now and then, The connections drops once per day on average.
And to be honest, My network is pretty solid, even without this feed. so I am not too worried about this at the moment.
