Thanks for the response but I have to disagree with you - I have read the responses time and time again with great attention, but to no avail. From what you said I understand that in order to utilize MAC address filtering I would need a managed switch or another box aside from the one that will be performing the NATing - is that right? Are you sure that there's no way to combine MAC filtering with NAT in a single box?
Just to make things clear I'll give an example of what I want to do - I want a machine with say MAC-a to have internet connectivity regardless of its IP address - that is I can assign to it any of the 192.168.1.Xaddresses. But if a machine with say MAC-b comes into the network and tries any IP I want it to be excluded from the NATd rule but still have connectivity with the FreeBSD box - so that I can open up a terminal and add it to the rulelist if I want Inet connectivity on that machine. P.S. I have heard of another way of filtering which uses the ARP tables - any comments on that? The thing that I don't think I'll be able to accomplish with the ARP tables is to use any of the 192.168.1.X IP addresses. Once again thanks for all your help and I hope we can reach the final conclusion of this problem. -- mEsS wItH tHe bEsT dIE liKe tHe rESt _______________________________________________ freebsd-ipfw@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "[EMAIL PROTECTED]"
