IKEv2/IPsec VPN

[Gerard Lally <gerard.lally%gmail.com@localhost>]

Some years ago I successfully set up netbsd-6 OpenVPN endpoints, with
20-30 remote Windows clients connecting.

I'd now like to set up a netbsd-8 VPN, based on IKEv2/IPsec. The
documentation doesn't make it clear -- to me -- if such a setup is
possible. Ideally it would be nice if strongSwan was supported on NetBSD
but it seems this is not the case. So where to begin? Does racoon
support IKEv2? At one stage there was a racoon2 fork but development
seems to have stalled on that.

If you run such a setup some ideas to kickstart my reading would be
welcome. Thank you.
