It is the default behavior of the kernel. But all networking software
dealing in security knows how to correctly behave. You are welcome to
inform me of something else suffering the same problem.

You should get into that debate. Proposing firewall workarounds is not a
correct solution so please don't do it. It needs to be fixed. It's an
immature VPN solution that always just proposed a workaround instead of
fixing the problem.
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".
