There wasn’t an attachment, but no matter. If it is working, great. I know a lot of older writeups recommend TAP because the assumption is that the OpenVPN server is on a machine behind the router. But for OpenWRT and other devices where the server is on the router itself TUN works fine and is a lot easier. At my primary home, my OpenVPN servers run on Asus routers. I have a plex server at my primary home, and it works fine to stream to a secondary home, an Airbnb, a hotel, etc, as well as to devices that can’t run TAP without rooting.
