Recently switched from PureVPN (that has a static port forward) to Proton VPN (which is dynamic one) in my docker compose configuration. (listed below for reference)

Theoretically should work fine.

1. GlueTun starts up, and connects to VPN, figures out what the port is
2. GlueTun runs an API command against qBT that sets the listening port
   • Also runs a different command when the VPN goes down

Here's the rub though: GlueTun comes up first cause qBitTorrent is dependant on it's network service.... but GlueTun can't set the port cause qBT isn't up yet. I basically have to start the stack, but then restart qBT when I see the GlueTun logs trying to connect to set the port.

Anybody have any idea's on how to get this to work together?
