As others have noted, it's *possible*, but there are pitfalls. Back in the early 2000s I did this a lot, and it worked fine. The scheme I used back then is described in, for example, <https://marc.info/?l=openbsd-misc&m=121155589425574&w=1> <https://marc.info/?l=openbsd-misc&m=125989140407974&w=1> But, this was an unsupported configuration, and I stopped using it a long time ago. I strongly suspect it would need changes to work on a modern OpenBSD.
