Above all, this means that UDP proxying now works for protocols which require
multiple packets to be sent back and forth between client and server, as
opposed to simple request-response DNS-like protocols.  OpenVPN is likely one
of the protocols which are expected to work now.

And yes, even for simple request-response protocols the performance has
increased significantly because the same session and upstream connection are
reused for multiple client packets.
