OK, I get what you mean now.
Yeah, probably it doesn't matter all that much which address is picked,
since it is NATted away anyway.
I was thinking that you'd need to have the same source address as the
kernel would pick when doing the connect(), but since the socket has
to be locally bound first before unleashing tproxy calls on it, this
is not an issue indeed.
