I use a site to site openVPN and RDP works very well between home and work. I have not looked into Wireguard yet and probably won’t until it makes it into pfsense. It’s supposed to be faster, but I’m not seeing any issues with oVPN even if I’m editing video on the remote end. I only have a 70/5mbps connection at home to give some sort of scale, work is gig/gig or maybe more now.
