Please could someone point me at the best VPN client to use on a Raspberry Pi (in a remote location) to create a permanent VPN back to my Mikrotik (where "best" in simplest and most secure to set up).
I have an IPSec/L2TP vpn already working between two offices, but want to put a RPi somewhere else. I can't find the "best" IPSec/L2TP client. I have just tried and failed with OpenVPN (out of the box OpenVPN3 does not use username, whilst Mikrotik requires it).
Thoughts welcome and thanks in advance.
