I'm currently using this docker with Mullvad VPN. Everything seems to be working fine, but how can I check that all of the traffic is truly going through the VPN for this Docker? I have VPN_ENABLED set to yes, and I have my Mullvad ID in VPN_USER and VPN_PASS, and then I have VPN_PROV set to custom. I've had a few terabytes incoming and outgoing, and haven't been throttled or warned yet, so I'm guessing that it's working, but I just want to be absolutely sure that all of that traffic is going through Mullvad.
Any tips are appreciated, thanks!!
