Original GitHub issue: https://github.com/hwdsl2/docker-ipsec-vpn-server/issues/27

Server info

OVH model name: MC-64-OC
CPU: i7-7700K overclock
RAM: 64GB
OS: Ubuntu Server 16.04 "Xenial Xerus" LTS

Log

birkhoff@bhs01:~$ sudo modprobe af_key
modprobe: ERROR: ../libkmod/libkmod.c:514 lookup_builtin_file() could not open builtin file '/lib/modules/4.9.13-mod-std-ipv6-64/modules.builtin.bin'
modprobe: FATAL: Module af_key not found in directory /lib/modules/4.9.13-mod-std-ipv6-64

Additional Info

I didn't check "Install original kernel" while installing the system. Will that be a problem?

Hello! Your server is using an OVH provided Linux kernel which may lack
support for IPsec. Please first ignore that error and see if the VPN works
fine. If it does not, you must switch to a standard Linux kernel provided
by your Linux distribution. See [1] for details.

Nope.

Write these down. You'll need them to connect!

Your server is running an OVH provided Linux kernel 4.9.13-mod-std-ipv6-64,
which does not support IPsec. You must switch to a distribution-provided
standard Linux kernel. Refer to the link in my previous reply for detailed
steps, or try Google.
