I would make sure that you are not mis-ascribing the problem* to "an immature VPN" and not what the default UDP behaviour of the kernel is, to pick a working interface to send packets from based on the routing table, in which any/all udp based tunnel would suffer the same problem. If you google it, you may find that other udp transports face the same "problem". *) https://en.wiktionary.org/wiki/Chesterton%27s_fence --=20 May the most significant bit of your life be positive.
