No, unfortunately.. divert is an IP level mechanism (wheras BPF is an interface and hardware level mechanism). BPF does let you write, but you can't stop incoming packets from being received (ie., you just get a copy, there's no way to actually "divert" them..) -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
