Would you share your knowledge of using TAP(4) as an alternative to the = generic vbox bridge mode? I cannot find much reference to that, especially when it comes to = running vbox on FreeBSD. If you have serveral vbox guests bridged to a physical "--bridgeadapter" = or to a tap device used as a bridge adapter - is there a way to lock = down / enforce an ip address for a vbox guest? I don't like the idea = that someone inside a vbox guests uses ip addresses for the guest, that = are already in use on the vbox server or uses non-allowed IPs. One possible solution I thought is to make the switch that the vbox = server hardware is plugged into, lock down the mac-adress of a vbox = tap-device to a fixed ip-adresses (if the switch is capable of that) Kai.=
