Not sure if this is the right place to post this. I have an ASUS AC86U and with AES-NI it kicks OpenVPN butt. However, I am unsure of how likely it is for ASUS to keep supporting it and upgrading the OpenVPN protocol on this thing. I've been looking into PiVPN and the Raspberry Pi 4 lately and I understand that the upcoming OpenVPN 3 protocol has support for multithreading. Here are my questions
- Some say that it is a better idea to run OpenVPN on your own open-source device (separate from the router) instead of running it on a consumer router. (more control, more security, more updates are the reasons I've seen). Others say it doesn't make a difference especially with a modern ASUS router. Do you find this to be true?
- If any of you are running PiVPN on a Raspberry Pi (any generation), what is the latest version of OpenVPN that it is capable of running? Is there any plan to support OpenVPN 3 in the future?

Latest firmwares from them are already running the latest 2.4.7 version (some models haven't received that firmware upgrade yet).

OpenVPN 3 is still in early development, and nowhere near production ready. There is no server support yet for instance, only client. It's also a bloated pig compared to OpenVPN 2.x, requiring a lot of external dependencies not typically found in routers (like d-bus).

I wouldn't expect OpenVPN 3 to appear in a hardware product for many years, and even then I doubt we'll see it appear in a router with limited flash space.
