http://www.openbsd.org/papers/slack2k11-on_compat_linux.pdf I've recently been using softether for my personal VPN's it's on Github I haven't tried to compile it for openBSD - but it's not going to help connect to random vendor Firewalls. I am unsure if Fortinet have a linux client, I imagine they must. OpenVPN works just fine under openbsd. -Joel On 10 October 2015 at 15:04, Jack J.
