You could also try nd remove TCP/IP from the stack on a Windows 98 box and
just use NetBui.

Raymond,
Yes, I am saying that you will need non-ip traffic to trigger the acl. Of
course, if it is non-ip, you will not have ip precedence or dscp to mark.
You could use IPX or appletalk or DECNET traffic. Perhaps you could use
clns packets from ISIS.
