It is still here, as I have tested it today with src r305790 (11.0-PRERELEASE). So please be warned. If you are using similar configuration as me with ipfw+natd+gateway, you can see unusual traffic on your outer network. In our case, three servers with outer interface on the same local network (broadcast domain) plus some workstations with netbios queries means seriously overloaded network.
