@zehome thanks, I understood

That's mean if I want make star topology (server is a center and many spokes) I need to run multiple instance of mlvpn daemon on a server side, one per spoke. Every mlvpn daemon will use one personal UDP port. That is right?

If we implement a multi-link UPD tunnel(or port forwarder) without VPN support, then use this tunnel to connect the OpenVPN server on the same VPS machine, we will get a star topology VPN. OpenVPN has a client to client feature, it is useful for some situations. But OpenVPN has no multi-link support, so we have to combine the two.

A UPD port forwarder with multi-link support and without root privilege, and can run in almost any OS, and make one server config can service multiply clients, it will be easy to use and awesome. Then let OpenVPN client connect the server through this multi-link UPD port forwarder, we can build a stable client to client VPN.

without root, you can't have a tun/tap interface. MLVPN uses privilege separation for increased security.

The VPN aspect is not mandatory, you can just have host to host communication, just don't setup any routes.

You can use openvpn inside, but you'll have very poor performance.
