How to set up phyphox experiment remote protected by proxy

[Romaxx]

I think it is a full tunnel.

Is there any workaround? I have to be connected to the VPN, so is there a workaround to access the data from the phone app withthout registering the device in the vpn via client certicicate?

SSH or access the Phone via its global IP, when connected to the internet (I know, this would mean traffic costs..)

Thanks!
