Crashing on start if VPN is enabled

[jschenke488]

I'm running the latest version as of June 24, 2023 at 15:13 UTC using Portainer, and get this error on startup if the VPN is enabled. All of the settings are from the PIA example (of course with my username and pass).

You are missing iptables kernel modules, without this the container cannot continue
