Hey guys, If access control problems are that severe, you should use some sort of smart card authentication. Or maybe 802.1x to authorize the link. But ISA Server won't allow MAC filtering. The reason is that ISA Server is an enterprise firewall, and the directly connected networks are typically stub networks, so there's not likely to be any hosts on them anyhow, except for maybe the DMZ segments, and you're not going to have users on those segments.
