What exactly are you trying to accomplish? A VPN server, a VPN home router or just connecting a single machine to a commercial VPN provider ...? For the latter, https://ipredator.se/guide/openvpn/openbsd/native was very helpful for me. Anyway, it may be a good start to read the OpenBSD VPN FAQ https://www.openbsd.org/faq/faq17.html IKED seems to be a good choice for many use cases. And of course, Peter Hansteen's "Book of PF" is a must read, although unfortunately, it doesn't mention VPN. But since PF is an essential part of OpenBSD's networking, I found it very helpful to at least read the first couple of chapters in order to get an idea of how things work in general. I have to admit that - for the time being - I gave up my efforts to build a VPN home router based on OpenBSD, since I ran out of time to find enough information to build it in a reliably safe way. Basically I'd prefer to stick to some lines of PF magic instead of throwing the big IKED at my humble task. Good luck!
