The fact that outbound forwarding sockets are bound to the loopback address, whereas inbound forwarding sockets are (by default) bound to the unspecified address leads to some unexpected differences between the paths setting up each of them. Happily there's an approach to tackling bug 100 which also reduces those differences, allowing more code to be shared between the two paths. Amongst other things, this will make the next steps of flexible forwarding configuration easier.
