Do you have funding to cover the paying the bandwidth costs which will ultimately result from this? Or if you're running this from a home network, does anyone know if OP should be concerned of running into issues with their ISP?
The tunnel host appears to be a Hetzner server, they are pretty generous with bandwidth but the interesting thing I learned about doing some scalability improvements at a similar company [0] is that for these proxy systems, each direction’s traffic is egress bandwidth. Good luck OP, the tool looks cool. Kinda like pinggy.
I can cover hundreds of PB of bandwidth per month if needed without paying a fortune.
