I have now sucessfully installed ISC:s DHCP server on my FreeBSD box to pass out IP:s etc. to the users on our local network, but I Have a little thing grinding on my mind, as I am going to use DUMMYNET and IPFW to regulate what users can and cannot do on other networks. Is there any way that I can check ( periodically or all the time ) that the IP the packet is coming from really is the one that is assigned by the DHCP daemon? What I mean is, for my ipfw rules/pipes to work, I need to be sure that the user has just that IP I have assigned to him. In other words, so he can't go in and change his Win95/NT/Mac and turn off DHCP and assign an IP on his own.. Is this possible to control at all? / Thomas Uhrfelt Datortekniker PlymoVent AB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
