from your code it always returns and not the correct origin if
your rule doesnt match. this is a different behaviour. before, the
origin was used as is and not modified.
if the origin is set to zero, the routing of the network doesnt work
anymore. this works for local multicast addresses, but not for neighbor
networks which are using the routing table
but correct me if i'm wrong
