Connecting Docker Container through VPN (PPTP)

Hello Community.

I have the following question:

I am trying to connect my docker container through VPN, but i didn’t make it to work.

When I configure the pptp , I use the command “pon [connection]” and I receive this:

Couldn’t open the /dev/ppp device: Operation not permitted
/usr/sbin/pppd: Sorry - this system lacks PPP kernel support

If any of you could help me with that , I would be really thankful.

Thank you
