I’m looking to expand and further secure my home server, and I’ve been poking around at the FUTO self hosting guide, and as a result I’m looking to host OpenVPN then connect to my services through that.

However, is it safe to have the machine running OpenVPN connected to my router, with my router operating normally, but forwarding the port to the OpenVPN server?

Then once I’m into that, I’d connect to what I’d like. Unless I’m misunderstanding, this would offer me sufficient security, correct?

I do have a backup RPi that I might end up turning into a router as the FUTO guide suggests, but I’d rather not mess with my network where possible, plus I’d need to buy a switch.
