Ali, I don't believe that there is. You do realize that MAC addresses can be changed and spoofed just like IP addresses so blocking by MAC won't really make your network more secure. Follow the link for a free MAC spoofing utility - supposedly it's a must have for every network administrator. Personally I think it's a must fire this administrator utility. http://www.klcconsulting.net/smac/ Amy -----Original Message----- From: Ali Meer [mailto:nadeem_elec@xxxxxxxxxxx] Sent: Saturday, September 18, 2004 2:43 PM To: [ISAserver.org Discussion List] Subject: [isalist] MAC address level blocking? http://www.ISAserver.org Hello guys, AOA is there have any 3rd party add-on to blocking client MAC address from preventation instead of ip blocking, any reply are really appreciated here.
