OpenVPN / OpenSWAN to Fortigate IPSec?

I'm a home lab user, and as such I don't have a full EMS configuration setup. However, I do have a couple of linux boxes out in the wild (my kid, and myself each have a couple). When we were running SSL VPN on my 60F, there was no issue. However, with it having been depricated and my possibly moving to a 90G in the near future, I'm looking for the next best option. After doing some research, it appears that the FortiClient VPN (Free) version no longer supports IPSec on Linux.

In the past, if I wanted to connect Linux to a SonicWall, WatchGuard, or pfSense box, I would use OpenVPN. So, I'm asking the community if they have used it to access their home lab remotely without having to rely on a secondary server sitting behind their gate.
