There have been reports of OpenVPN traffic being discovered as VPN traffic even after using obfuscation with obfs-proxy. I believe SSL VPNs are coming out for the self-hoster, and I’m personally very interested in SoftEther

I plan to use podman at home since I just have one node and I don’t care about HA as much (what will I even do HA with? VMs?).

If you have multiple nodes for an HA setup, sure, go right ahead. It will be a massive learning curve though. But so are most things in life. I think everyone can learn a lot by running kubernetes (godly complex networking in my opinion).
