Of course, packets with zero address cannot be sent out.
If udp source is zero, it means only that kernel should select
some valid address itself.

Apparently, the interface is selected to eth1 because of another bug.
I think, pump crapped routing tables as well. It is rather "unlucky reason". 8)

Probably, this client looks like working on single interface machine
but only for (un)lucky reason. 8)
