Archlinux setting up VPN - couldn't open the /dev/ppp device: No such device or address

While configuring VPN on archlinux I followed the guide on:
https://wiki.archlinux.org/index.php/PPTP_VPN_client_setup_with_pptpclient


archlinux couldn't open the /dev/ppp device: No such device or address


SOLUTION:
add a new file:

nano /etc/modprobe.d/modules.conf

with the line:

alias char-major-108 ppp_generic
