Need help with iptables
Trying to create a whitelist to limit bandwidth. My sync speed is 1536/256 kbps.

Simple rules in order:

1. Do not limit (or set to 1536/256) MAC 00:00:00:00:00 (computer is in 192.168.1.0/24).
2. Do not limit (or set to 1536/256) MAC 00:00:00:00:01 (computer is in 192.168.1.0/24).
3. Do not limit (or set to 1536/256) MAC 00:00:00:00:02 (computer is in 192.168.1.0/24).
4. Do not limit (or set to 1536/256) MAC 00:00:00:00:03 (computer is in 192.168.1.0/24).
5. Limit IP range 192.168.1.2 -> 192.168.1.254 (or all MAC/IP's) to 500/60 kbps.

This is the code which i was given and it doesnt work

Code:

tc-fw

Firewall mark classifier in tc(8)				       Linux					 Firewall mark classifier in tc(8)

NAME

       fw - fwmark traffic control filter

SYNOPSIS

       tc filter ... fw [ classid CLASSID ] [ action ACTION_SPEC ]

DESCRIPTION

       the fw filter allows to classify packets based on a previously set fwmark by iptables.  If it is identical to the filter's handle, the fil-
       ter matches.  iptables allows to mark single packets with the MARK target, or whole connections using CONNMARK.	The benefit of using  this
       filter  instead of doing the heavy-lifting with tc itself is that on one hand it might be convenient to keep packet filtering and classifi-
       cation in one place, possibly having to match a packet just once, and on the other users familiar with iptables but not tc will have a less
       hard time adding QoS to their setups.

OPTIONS

       classid CLASSID
	      Push matching packets to the class identified by CLASSID.

       action ACTION_SPEC
	      Apply an action from the generic actions framework on matching packets.

EXAMPLES

       Take e.g. the following tc filter statement:

	      tc filter add ... handle 6 fw classid 1:1

       will match if the packet's fwmark value is 6.  This is a sample iptables statement marking packets coming in on eth0:

	      iptables -t mangle -A PREROUTING -i eth0 -j MARK --set-mark 6
